[Global Math] Recording of my presentation on Teacher and Student questions

I just noticed that I can embed recordings of presentations from Big Marker, so I decided to embed my presentation for the Global Math department here. The presentation topic was "Teacher and Student Questions." You can view the slides here.

 

My son, the math teacher

My son went to a full day session to meet up with some other children around his age who are being homeschooled. During this time he had a class on engineering with Lego, and a lot of free time with which to play and socialize with the other children.

Interestingly enough, the kids decide to play the Game of School. They found a chalkboard and took turns pretending to be the teacher and explaining things to the other students. My son decided to be the math teacher, and according to him, this is what he tried to explain.

Workshop on Social Media for Students

I recently facilitated a workshop on social media for a school. I created two short videos to act as discussion starters, and then I created a workshop structure around the video clips that the school could use to facilitate the discussion with their students.

Learning about shape

As I watched my son over the past few days learn about shape, I am struck by not only how much we need to learn to make sense of the world, but also by how even simple things cannot be taken granted as known by children.

This is an excerpt from a conversation I had with my son while we were walking from the subway to the theatre.

Teaching proof

I'm currently working on creating a sample sequence of lessons for teachers to use for a geometry unit. At this stage, students will have been exposed to (but will not necessarily have learned all of) geometric transformations, constructions, and some review on geometric vocabulary.

My objective is to create a sequence of lessons which include:

Why teach math?

Why do we teach math?

How do you define variable?

I recently read the Common Core standards for Math for grade 6, which is where the concept of variable appears to be introduced. The standard in question reads:

Write, read, and evaluate expressions in which letters stand for numbers.

I tweeted this out, and one person responded with this observation:

Getting started with programming JavaScript

JavaScript is one of the primary web programming languages. It is the language used in Google Apps Scripting, and in HTML5 interactive documents. Chances are pretty good that most of the interactive features that you see in websites were coded in JavaScript.

So you want to learn to program...

When I was 8, my father gave me my first computer. There were two things I could do on this computer; program or write. I found programming to be much more interesting! So with a little bit of support from my father, and a copy of the Wang BASIC reference manual, I began the long process of teaching myself how to program.

Here is basically what you need to learn how to program:
