Pay Down Debt First, or Keep Savings Intact?

April 26, 2013

My mother has offered to give us a small amount of money, which we can either use to pay down most of our debt, or we can put into a savings account, and then pay down the debt over time.

My wife and I have been debating which is the better course of action. After playing around in Excel, I decided to write a script to help us resolve this issue. See http://davidwees.com/javascript/debtsavings/. 



Learning Math Through Programming

April 22, 2013

My previous article focused on using programming as an example of applying math one already knows to a different context. The purpose of this article is to describe how one could, through programming, learn a new mathematical concept.



Applying Math in Programming

April 18, 2013

The purpose of this post is to show an example of using math in the context of programming. I've written the post as I created the project, to try and outline my thinking during this process as much as I can. This is an example of me applying math that I know to a different context, creating a spiral of numbers. In a future post I plan on exploring what learning new mathematics through programming could look like.



Math in the Real World - Video

April 16, 2013

I've created a video summary of the workshop that I facilitated recently on math in the real world. You can watch it below.

My presentation slides for the original workshop are here.



Math in music

February 27, 2013

I'm always on the look-out for ways of finding connections between mathematics and other areas of knowledge. Music is one of the areas of knowledge that I know has some similarities with mathematics, and so I've been brainstorming ways one could incorporate music into a mathematics classroom. Here are a few examples.



Colouring problems

February 22, 2013

I'm currently working on math enrichment activities with some 3rd and 4th grade students. Aside from using some standard resources for enrichment, I'm finding that I can find challenging problems from different areas of mathematics and find ways to introduce the main concept to students in a context they understand.



Paper folding activities

February 20, 2013

I've been playing with paper folding recently, and exploring the mathematics involved. I'm simply amazed by the number of mathematical ideas that can be represented by paper folding, so I thought I would share a few of my discoveries here.

Math in the Real World presentation

February 15, 2013

I am presenting in Hope, British Columbia today, on the topic of Math in the Real World. Here are my presentation slides.



A factoring success story

January 22, 2013

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.
