Here are four videos that represent the perspectives of students with various learner characteristics. Imagine you have these four students in your class. How might you support them?

These four students have different needs but some discussions of students with special needs treat all of these students as being identical. For example, I recently got asked how to best support the students in a school with special needs. My first response, which I kept to myself, was to figure out what their special needs are and meet them.

My next response was to share these three resources:

Use instructional routines as part of core instruction. These routines embed supports that aim to improve the odds that all students understand the mathematical ideas being shared. Further, the use of routines reduces the cognitive demands students (and coincidentally their teacher’s cognitive demands as well) often have around making sense of frequently changing instructions and structures for working with other students. When these demands are reduced, students have more cognitive space available to make sense of mathematics.

Many of the strategies embedded within the routines can be used outside of the instructional routines. These strategies are also described in detail by Grace Kelemanik and Amy Lucenta in their book, Routines for Reasoning.

Instead of making assumptions about what students with special needs can or cannot do, determine what the specific needs are of the students you have, and then make your best effort to meet those needs.

There is a problem with the third set of resources as they essentially follow a diagnostic model — figure out the problem and then assign a cure, but many advocates for students for special needs want us to stop considering the students broken, and instead think of them as whole human beings who have needs, just like everyone else. I’m actually not sure how to provide helpful advice and resolve this issue comfortably.

I recently had someone ask me this question on Twitter and I think it’s an important question!

How do you plan a succession of lessons for a maths topic, say multiplication or division?

As it turns out, I’ve spent the last 4 years planning sequences of lessons as part of the curriculum work I do with a team of math specialists, so I have some significant experience with this task.

Decide what success looks like

The first step in our process was to decide on a logical sequence for the units of study for the year. Given the amount of time we had to devote to curriculum development six years ago, we basically decided to outsource this part of the process to the Mathematics Design Collaborative, but there are a lot of ways to decide on an order to units and to some degree, the choices are arbitrary. It’s what comes after that is critical but this allowed us to decide on an initial apportioning of the content standards to specific units.

We started with assigning a formative assessment lesson from the Mathematics Assessment Project to each unit, essentially deciding on “what does it look like to be successful in the mathematics of this unit?” first before outlining the mathematics of the unit. This decision, to work backwards from the end goal, is described in more detail in Grant Wiggins and Jay McTighe’s book, Understanding by Design.

Decide what a unit looks like

My colleague, Russell West, created this Unit Design Schematic to outline the general structure we intended to build for each unit.

Align mathematical tasks to the unit

6 years ago, we had a partnership with the Silicon Valley Mathematics Initiative, and they have literally hundreds of rich math assessment tasks aligned to high school mathematics. I printed out all of them for middle school and high school and we put them on a giant table in our office board room. My colleagues and I then sorted all of the tasks into the units where we felt like they fit best (or in some cases to no unit at all). Our experience suggested that tasks are a better way to define the mathematics to be learned than descriptions of mathematics.

Once we had descriptions of the units, formative assessment lessons, and tasks for each unit, we decided an initial task and a final task for each unit. The goals of the initial tasks were to preview the mathematics for the unit for students and teachers and to give students and teachers a sense of what prerequisite mathematics students already knew. The goals of the end of unit assessments were to assess students understanding of the current unit and to give students and teachers a sense of the end of year assessments, which in our case are the New York State Regents examinations.

Be really specific about the mathematics to be learned

With all of this framework in place and a structure for each unit defined, we then did all of the tasks we had grouped into each unit ourselves, ideally a couple of different ways, and made lists of the mathematical ideas we needed to access in order to be successful. Essentially we atomized each task to identify the smallest mathematical ideas used when solving the task, but we were careful to include both verbs and nouns and created statements such as “describe how independent and dependent quantities/variables change in relation to each other.”

The next part of the process took a long time. We wrote descriptions of the Big Ideas and the evidence of understanding that would tell us if students understood the big idea for the week. This evidence of understanding was essentially the result of the atomizations that we had previously created, grouped together into week-long chunks. The process took a while because we wrote and rewrote the evidence of understanding statements so that our entire team and a sample of the teachers we worked with felt like we understood what the evidence of understanding meant.

For example, the first Big Idea of our Algebra I course is “Rate of change describes how one quantity changes with respect to another” and our evidence of understanding, at this stage in the course, include statements like “determine and apply the rate of change from a graph, table, or sequence” and “compare linear, quadratic, and exponential functions using the rate of change”. The last Big Idea of our Algebra II course is “Statistical data from random processes can be predicted using probability calculations” and the evidence of understanding for this Big Idea includes statements like “predict the theoretical probability of an event occurring based on a sample” and “compare two data sets resulting from variation in the same set of parameters to determine if change in those parameters is statistically significant”.

Once we had this evidence of understanding mapped out, we also checked to see whether important ideas would come back throughout the course in different forms and looked to make sure that deliberate connections between different mathematical representations were being made. This way students would get the opportunity to revisit ideas, make connections between topics, and have opportunities to retrieve information, frequently, from their long-term memory.

We also revisited the alignment of the New York State Learning Standards to our units, and ended up adding standards to some units, moving standards around in some cases, and writing some clarifications about what part of a standard was addressed when during the course.

Design tasks for each chunk of mathematics

Now, finally, we were ready to make tasks. Well, actually, in practice we started making tasks as soon as we had a sense of the Big Ideas and then occasionally moved those tasks around when we had greater clarity on the mathematics to be taught. But once we had nailed down the evidence of understanding, we were able to map the evidence of understanding for a week to specific activities, essentially creating blueprints for us to design our tasks from, since each of the evidence of understanding statements were linked to observable actions of students.

We ended up with a final product we called a Core Resource. It’s larger than a single lesson but it’s not just a random collection of lessons either. It’s a deliberately sequenced set of activities meant to build toward a coherent larger idea, while attending to two practical problems teachers encounter frequently – that of students forgetting ideas over time and needing a lot of time to build fluency with mathematical representations. Here is a sample Core Resource for Algebra II.

Summary:

In hindsight, the most important parts of this process are:

to work backwards from the goals at the end of a year and the end of a unit,

use tasks as examples of what success looks like,

be really specific about what the mathematics to be learned is,

chunk the mathematics into meaningful pieces,

and then finally design tasks that match the mathematics.

For multiplication and division specifically, I would be tempted, as much as is possible, to frequently interleave the two ideas together, after identifying the many constituent mathematical ideas that together represent these large mathematical ideas. For example, if students learn to skip count by twos, five times, to find how many individual shoes are in five pairs of shoes, I would want to work backwards fairly soon from there to I have 10 pairs of shoes, how many pairs do I have, so that students can more directly see these two operations as opposites of each other.

In 4 months, the grant that funds the consulting on curriculum and professional development I do with New Visions for Public Schools ends and unfortunately, it does not look like a new grant is on the horizon. Consequently, with blessings and support from my colleagues at New Visions, I am looking for either another consulting contract or full-time employment.

The work I do is extremely varied. This past month I:

Designed and ran two workshops for teachers on using mathematics curriculum aligned to Geometry and Algebra II curriculum,

Created interactive dashboards using Data Studio to display historical data from the NY Regents exam,

Wrote a script to automate responses to the thousands of Google Doc share-requests my colleagues were receiving,

Wrote a script to automate conversion of Google Docs into PDFs,

Created two videos examples of classroom teaching in action (example),

Double-checked that typesetting we had done is correct for thousands of math and science questions for this Google Sheets add-on,

Supported a new assistant principal to make plans for her math team,

Other smaller tasks related to supporting 80 or so secondary schools with their mathematics instruction.

Here is an overview of my professional skills.

I live on a small island off the coast of British Columbia, Canada where I grew up. It is beautiful and we are settled. If it is absolutely necessary, I will live apart from my family for at least part of the year, but ideal work for me would allow me and my family to remain where we are. I don’t mind traveling if it is necessary for work.

I’m looking for work that makes use of my skills and allows me to grow and continue to be challenged to learn new things.

You can help by:

Giving me encouragement and cheering from the sidelines,

Suggesting opportunities and organizations that will meet my needs,

Sharing my resume with people and organizations that you think may be interested in someone with my skills.

As some of you probably know, I’m one of the lead designers on an open source math curriculum. Today I had an interaction that reminded me of a key benefit of open source curriculum.

In a traditional curriculum model distributed either on paper or via PDF, Hannah would have to either print and then painstakingly correct the errors above by pasting over them or use some likely-painful-to-use PDF editing software to fix these errors.

We distribute our open source curriculum via Google Docs and as a result Hannah can just make a copy of the document, make the edits she wants, and then print the resources for her students. Hannah is also legally able to do this because our curriculum is licensed specifically for adaptations.

Since each resource we create has its own page on our website (the resource Hannah describes is here), Hannah was able to comment on a specific document and I was able to respond to her transparently.

There are drawbacks of using Google Docs. For example, it is not currently possible with our curriculum to print out the entire set of student handouts. This is a fairly frequent request we get from teachers but we don’t know yet if the loss of editability is worth the increased ease of printing resources.

It would be helpful for me to know what other pain-points exist for teachers when adapting and modifying curriculum for their own classroom use, especially given that a high percentage of teachers make adaptations to curriculum they are given. If you were in charge of how someone shared curriculum, what would make it as easy as possible for you to make thoughtful changes to that curriculum?

I have been to perhaps a dozen national conferences and to two dozen or so regional conferences across the United States and Canada. With the exception of one or two of these conferences, I regret having ever attended.

My regret stems not from finding the conferences uninteresting or not enjoying meeting people face to face that I had only ever met previously online, my regret stems from the fact that I think these conferences are fundamentally immoral when our world is in crisis.

Conferences that draw people from all over a country or all over the world require participants to fly to a single destination. This results in thousands of people flying to destinations whom otherwise would not be flying. Unfortunately, flying in an airplane carries with it a huge carbon footprint. One flight across a continent or across the Atlantic has roughly the same carbon footprint as using a car for an entire year.

Here is an aggregated list of conferences across the United States. I counted 1374 conferences occurring next year, each of which may have many hundreds to thousands of participants. That’s potentially millions of flights each year for people to attend these conferences.

Maybe these conferences would be worth their carbon footprint if people learned something significant from them that changed their practice. But my experience is that this is not true. In most cases, I suspect that if a few people took two days off from work and read the same good book about teaching and then planned together based on that book, they’d get as much (or more!) out of those two days than they learn from attending 10 different scatter-shot presentations. Sessions are just not typically long enough to result in tangible learning and presenters often just don’t know the actual audience of teachers they end up with well enough to plan a session that meets those teachers’ varied needs.

It’s true that once in a while I’ve attended sessions that really made me think. A few years ago, I attended the NCSM and NCTM conferences back to back, focusing only on sessions on instructional routines, only attending sessions by a group of people who worked closely with Magdalene Lampert on these routines. That was a hugely valuable conference for me! But 1 hugely valuable conference out of the 18 or so I have attended does not justify the environmental cost of these conferences.

I think that we might be able to replace national conferences with the following and to some degree, this may produce similar learning for participants:

Virtual conferences: Sessions are run via web conferencing software. These are ideal replacements for non-interactive (or minimally interactive) presentations that dominate most conferences.

Book study groups: Grab 2+ friends and take two days off from work. Everyone reads the same book on day 1, on day 2, everyone convenes to first describe what things they learned and then make plans to implement some of the suggestions.

Run smaller regional conferences: I know everyone wants to see Fawn Nguyen, Jo Boaler, or Dan Meyer speak at conferences, but I believe there is lots of local expertise in most parts of the world that could be drawn upon instead.

This year I cancelled my presentations at the NCTM annual conference, the NCTM regional conference in Seattle, and CMC South in Palm Springs. I went to one conference that I could drive to up at Whistler, the Northwest Math conference (it was really good). I do not intend to submit proposals to conferences in the future that require me to fly to the conference.

Geometric constructions are amongst my favourite things to teach in Geometry. Why? I see each geometric construction as a puzzle to be solved and I love watching children solve puzzles and share their solutions to those puzzles.

Puzzle #1: Given a line segment, draw a circle with its radius as the line segment.

Many constructions build on earlier constructions so that as students figure out how to do earlier constructions, they build the pieces they need to figure out more complex constructions. Further, more complex constructions embed all sorts of opportunities for practicing earlier constructions.

Puzzle #2: Draw another line segment with the same length as the given line segment with an endpoint on either A or B.

The invention of dynamic geometry software, like Geogebra, means that students can learn these earlier constructions without their early challenges using a compass and straightedge interfering with their ability to learn the mathematical ideas behind the constructions.

Puzzle #5: Draw a line segment that is exactly three times the length of the given line segment.

It is super helpful for students to have their prior work with constructions visible for themselves as examples to work from, and so once students have figured out how to do a construction with the digital tool, I have them transfer their construction to paper (ideally in their notebooks for reference) so they can access it later.

Puzzle #10: Draw three overlapping circles on the same line such that two of the circles have their centers on the middle circle.

Another advantage of the digital geometry tools is that you can provide partial constructions for students. This way students can work on the part of the construction that is new. This doesn’t give students practice with the earlier part of the construction but it is a subtle way to give hints to students for particularly complex constructions.

Puzzle #11: Use the circle below to help you draw a regular six-sided shape (regular hexagon).

When a student shares their constructions with the class, I usually call up a volunteer that is not that student to come up to the front of the room and perform the construction, following the verbal instructions from the first student. This means that the pace of the construction is likely to better match the pace other students can follow or copy the construction which leads to more students understanding the construction. After the construction is complete, I can ask another student to restate the instructions while I annotate important features of the construction.

Puzzle #17: Construct an octagon (regular 8 sided shape).

The last few constructions, I provide the least amount of support for students since a goal of mine is to see if students can do these constructions independently. However, note that in the instructions for the constructions, I try to make sure that the language of the constructions isn’t a barrier for my students.

Great teaching is more than putting good tasks in front of students because a good task enacted with terrible pedagogy is still terrible teaching. While I think hardly any teachers are terrible, every teacher can be better than they are.

I see a lot of sharing of tasks, games, and activities via Twitter and blogs, but I see much less sharing of pedagogical strategies teachers would use with those tasks, games, and activities, which means a lot of people are losing potential opportunities to learn about pedagogy.

Often people share routines like Which One Doesn’t Belong or Connecting Representations which on the surface look like pedagogical strategies, but while the names themselves are somewhat descriptive, they aren’t sufficient to understand the routines they describe.

A new project we are working on is to share the instructional components that make up the routines. Here is a video showing different talk moves that can be used by teachers, either within the routines or whenever they are needed.

Here is another video showing Kit that focuses on the annotation he did while another student restated the strategy of another student, showing that these different instructional strategies can be used together and towards specific instructional goals.

It is important that explanations in the math classroom are clear and complete so that all students can follow the mathematical arguments presented. Here is one of our teachers describing how she supported students in creating clear mathematical arguments for each other to follow.

Are videos like these helpful? Would more videos sharing some of these strategies be helpful (if so, which)? And can we share more math pedagogy with each other?

A friend of mine has been fostering a child that has been diagnosed with both autism and cerebral palsy. They have seen him grow from a child who could not talk and who had a great deal of difficulty using his body to a child who asks for help when he needs it, communicates his needs and interests with others, and who can climb up a climbing wall without difficulty.

My friend shared that they were quite shocked during recent parent-teacher interviews when they were shown her foster child’s “work” from the term. They were blissfully unaware during the first couple of months of school, during which their foster child enjoyed going to school and they believed he was also getting an education, that the he was in fact not being educated. Their biggest concern was that the work he did do, circling a few answers on 2 or 3 review worksheets each day, was not helping him progress. They wondered, what does he do all day?

Their position is that while it is true that this kid is behind, not giving him any productive work to do is not going to help him catch up. They are very worried that his needs are not being met, and I agree with them. I worry that his teacher is “meeting him where he is at” and that this means that he has little to no opportunities to grow. When this child has been supported and pushed to grow, he has responded by learning and growing immensely. The extremely low expectations that this child’s school has for him risk his future.

So what would you do if you were this foster parent?

There are two common activities teachers do that have either little to no impact on student learning but which do take teachers a tremendous amount of time, time that could be better spent on other activities.

Grading Student Work

There’s limited evidence that putting marks on students’ papers leads to students either being more motivated to work harder or that these marks leads to increased student learning. In fact, some of the literature on feedback suggests exactly the opposite is true:

When teachers pair grades with comments, common sense would tell us that this is a richer form of feedback. But our work in schools has shown us that most students focus entirely on the grade and fail to read or process teacher comments. Anyone who has been a teacher knows how many hours of work it takes to provide meaningful comments. That most students virtually ignore that painstaking correction, advice, and praise is one of public education’s best-kept secrets.

But grading student work is extremely time-consuming and so if this effort doesn’t lead to student learning, why do we do it?

To communicate progress to children and their parents,

To evaluate students,

We are expected to grade student work.

In a recent parent-student-teacher interview, the teacher had samples of my son’s work in front of him. He shared directly what he liked about his work and where he thought my son could improve and we never talked about the numbers at the top of the paper at all. It is easier to communicate progress using artifacts of student learning.

Schools, in the interest of focusing on activities which have clear connections to student learning, should stop grading students and focus on time-efficient ways to solve the problems grading is intended to solve. Should teachers still look at student work? Definitely, but this should be as part of their process of planning future lessons and thinking about opportunities for feedback for students.

"When you grade, you help one child at a time. When you plan, you help all kids. Spend your time accordingly." ~ @hpicciotto#NCTMregionals

I spent years writing tasks for each of my classes, borrowing from other teachers when I could, but mostly making my own resources from scratch. These resources were not of much higher quality than what I could get from a textbook but I understood how they were designed and how I intended to use the resources. Writing curriculum took me SO much time.

Now I write curriculum about 50% of the time for my day-job and can see that the curriculum I currently create is far superior to the curriculum I used to create and far more complete and coherent. But it probably suffers to some degree from the same problem that led me to create my own curriculum as a teacher — it is extremely difficult to make sense of someone else’s lesson or task.

One feature of the curriculum I write that I think helps mitigate this problem of understanding curriculum is that it contains instructional routines. Once one knows a particular instructional routine, the task of understanding tasks to go along with that routine is far easier. Teachers who know the Connecting Representations instructional routine can look at tasks and are better able to make decisions about which tasks to use and why.

Evidence on use of curriculum suggests that all teachers benefit from access to high quality curriculum resources. In this experimental study some teachers were given access to Mathalicious and others were not, and the teachers who had access saw better performance from their students.

What I think teachers should have more time to do is modifying and adapting curriculum for their particular context and their particular students. This is why our curriculum is licensed with an open license and why we share the curriculum in Google Document format — it makes it much easier for teachers to adapt and modify the curriculum rather than having to recreate a document from scratch just because the original is locked in PDF format.

We also wrote our curriculum to be largely sequenced but with lots of opportunities for teachers to make choices within the curriculum or to design their own tasks. Our tasks are aligned to the evidence of understanding we expect to see in students, which means the blueprints for constructing their own tasks are available to teachers as a support – leading to the best of both worlds for teachers: the autonomy to construct their own curriculum while not needing to reinvent the wheel each day.

Teaching Better

If teachers stopped grading all student work and writing all their own curriculum from scratch, then they would have more time for other tasks that contribute more to student learning such as:

Designing responses to evidence of student achievement (eg. formative assessment),

Collaborating with colleagues to investigate instructional strategies (eg. micro-teaching)

Work with individual or groups of students to support their learning.

What else could teachers do with their time to support student learning if all of a sudden they had more time available?

A number of times over the past few years, I have been confronted by a phenomena I do not understand: children being handed workbooks and, with very little to no instruction, expected to complete the workbooks and develop an understanding of the material contained within.

For some children this works out fine. The workbooks, mostly being designed for independence anyway, are sufficient for children who have some background in the material and see the patterns developed within the workbooks. For many children however, the experience is potentially one of frustration and humiliation: they have been given a task that their teacher clearly expects them to be able to do, and they cannot.

I have seen workbooks handed out with minimal to no instruction in two very different kinds of circumstances. In one case, the teacher sees a class with a diverse needs and although all of the students had the same overall goals for the class, students clearly have different levels of preparation and interest in the course. The other case is when teachers have a multi-age classroom (which also contains students with different levels of preparation and interest) and no time to actually teach anything at all. Both of these are compounded by the preparation of the teacher leading the classroom to deal with varied needs.

I have been in the first case, leading a group of students with varied needs but with the same goal, many times during my career. The best solution I have learned is the use of instructional routines with designs for interaction to support a varied set of needs, while working together towards the same mathematical goal.

As for the second case, when teachers have a multi-age classroom, I don’t know for sure what I would do. If I found myself teaching in such a classroom, I think I would do two things; teach mini-lessons (using a variety of formats depending on the mathematical goals, but again instructional routines seem like a good fit) and assign problems from a somewhat independent workbook, and then while some students are working in the workbook, engage the other students in a mini-lesson on a different topic. I would have to organize the space so that students who were working on similar material sat together and I would need to develop classroom culture so that students knew to talk to each other after first trying the math themselves and to wait until I was available to assist. I would also look for places in the mathematical goals for the year where potential alignment between different grade levels occurs and use these opportunities to engage the entire classroom. For some students the activity might be review and for other students the activity might be somewhat new material, but both of these seem like helpful ways to use classroom time.

Imagine you are teaching a classroom with 20 students roughly evenly distributed from grade 2 through 7 (age 7 through 13). What would you do to meet the needs of these learners?
