Math in the Real World presentation

I am presenting in Hope, British Columbia today, on the topic of Math in the Real World. Here are my presentation slides. You will probably notice that sections 6 and 7 of my presentation are not completely focused on the topic of “math in the real world” but I feel like they are such important […]

A factoring success story

I covered a couple of my colleague’s classes yesterday so he could attend a math conference. The afternoon class was a somewhat boisterous grade 10 group. I was asked to teach students how to find the greatest common factor, and if I had time, introduce them to more general factoring techniques. I decided that the […]

Investigation into scoring systems

I played ultimate tonight, and we usually keep score with shoes. Our normal scoring system is to count in base 5. Tonight, I tried to use binary, but at half-time I switched back to base 5 when most of our team struggled to read our score quickly. I took some pictures of the arrangement of […]

Inquiry into positive and negative integer rules

Our department had a meeting recently where we discussed the need for more investigative approaches in our teaching. We all use investigative approaches at least part of the time, but some of us disagreed about whether it was possible to approach every topic with an investigation.  One of the specific topics that came up was […]

Bean counting and place value

One area of mathematics which I strongly suspect many students have problem understanding is place value. It is an important abstraction for students to understand, and without understanding it, it is unlikely that students will progress very far in arithmetic (and then will likely struggle in algebra later). Here is an activity my friend David […]

Find the area of a leaf through calculus

(Image credit: Kumaravel) After reading Bruce’s post this morning about finding the area of a leaf, it occurred to me that this could be solved using calculus. The basic project would be for students to collect some leaves, trace them onto graph paper, determine through modeling the equations that correspond to the edges of the […]

A math question

I’m working on a system where students will be able to post their non-digital work directly from a scanning station to their eportfolio blog. I want to make the system simple enough that young kids can potentially use it themselves (and ask our teachers to review the portfolios of our students periodically). To this end, […]

Different multiplication strategies

I’m investigation possible models for learning multiplication. Below there are 6 possible models. I’d like to know if you know of more models. I’ve found 12 different models for understanding/doing multiplication over at Natural Math, but have not found explanations of all of these that I can easily share. Interestingly enough, many of these videos […]

Math activities for a measurement unit

Our 3rd grade students will be doing a unit on measurement soon. These are the specific standards for the measurement unit that we hope to address. I’ve been asked to brainstorm some activities for students in this unit which can be extended or modified to meet the needs of a wide range of learners.   […]

Resources for mathematics enrichment

I’m currently putting together a list of resources for our elementary school teachers to use to enrich their mathematics classrooms. Our basic philosophy is to provide opportunities for all students to engage in rich mathematical tasks, and to add breadth & depth to their program of mathematical study, rather than accelerating through the British Columbia […]
