Math in the real world: Marshmallow constructions

This is another post in my series of posts on math in the real world. My wife, son, and I  went to a kids science event at SFU today, and at one table they had some marshmallow diagrams set up to demonstrate molecules. They let the kids play with the marshmallows and toothpicks, so my […]

Workplace mathematics

Here are some videos on mathematics in the workplace I’d like to watch later, when I get a chance. Thanks to Gary Davies and Lorri Carroll for sharing them with me.

Learning Origami

I started learning origami again this past weekend. So far I’ve built a swan, and a couple of paper airplanes that are more advanced than what I usually make but none of it has been particularly complicated to make. I’ve often thought that origami would be a fun hobby, but that I wouldn’t find much […]

Math in the real world: Balloons

This is part of a series of posts I’m doing on math in the real world.   The first question I thought of when I saw these balloons in my colleagues office was, how many of those would I need to be able to float? Clearly, this is a math problem, and one students can […]

Numeracy for preschoolers

Bon Crowder has started an initiative to embed numeracy in the early lives of children via their parents, which she calls Count 10, Read 10. The basic idea is to split up the 20 minute of reading for parents into 10 minutes of numeracy and 10 minutes of literacy every day.  Most parents aren’t reading to their […]

Math in the real world: Sound

This is another post in my series on math in the real world. Vi Hart explains much of the mathematics behind noise in great detail, so watch her awesome video below. Thanks to @delta_dc for sharing it with me.   Notice her use of Audacity? I think we could quite easily turn this into a […]

Math in the real world: Roller coasters

This is another post in a series I’m doing on math in the real world.   When my son and I were on the roller coaster, I was again in awe about how quickly even a small roller coaster like this travels, and how it doesn’t drive right off the tracks. Roller coasters have to […]

Math in the real world: Leaning Plants

This is another post in my series on math in the real world.   View all pictures   When plants lean over due to being pulled by gravity, they often form a similar shape. With some exploration, we can determine what shape this is (at least approximately). First, I opened up one of these pictures […]

Math in the real world: Relationships

This is another post in a series I’m doing on math in the real world. Image credit: mvplante There is a lot of different types of mathematics in family relationships. For example, each generation you go back, the number of ancestors you have increases exponentially. This works, of course, since we all have a lot […]

RSCON3 presentation online

I’m happy to report that the recording from my Reform Symposium presentation on Interactivity and Multimedia in Math is available to be downloaded here. Almost all of the recordings for the other presentations are up as well, which you can access here. I’ve also uploaded my presentation slides here, so that you can download it and […]
