Prime Climb Puzzles

Let it be known that I am not a huge fan of math board games. That being established, I have tried on multiple occasions to create one that I like because the undeniable engagement factor is there. One of two things always seems to happen to my attempts: The game does nothing to change how students interact with the mathematics. Rather, it divulges into an attempt to get students to complete drills in order to win points of some type. Here, the math and the game exist as ostensibly separate entities.  The game mechanism does not support flexible mathematics without …

What High School is (Often) Missing: A Conversation with a Kindergartener

Sometime after pyjama time and before bedtime, a math conversation broke out. My wife and I were visiting some good friends, when the topic of a recently purchased board game came up. It was bought at a teaching specialty store and designed to teach addition and subtraction of twos. After examination, I didn’t like the overly symbolic structure, and asked their 5-year old if she wanted to play a math game. She ran and got a piece of paper. When she finally got called up to bed (much later than expected) I took the page and folded it into my …

Algorithms and Flexibility

I was given a section of enriched grade nine students this semester. I decided very early on that the proper way to enrich a group of gifted students is not through speed and fractions. They came to me almost done the entire course in half the allotted time. This essentially alleviated all issues of time pressure.The beautiful thing about this is we are able to “while” on curiosities that come up during the class (Jardine, 2008). I am not afraid to stop and smell the mathematical roses–so to speak. In a recent tweet I explained it as the ability to stop and …

Dice Sums Task

Dice are familiar tools in most mathematics classrooms. Their use in primary school games allows students to build preliminary notions of number and autonomy. (see Kamii) As the grades progress, dice sums become too simple and the tool is pushed into the realm of probability and chance. There, alongside decks of cards and coloured spinners, it enjoys almost godly status; it seems that there is no better way to calculate odds than to role dice and spin spinners (in outrageous cases—simultaneously). The greatest thing dice have going for them is familiarity. Teachers can use this to upset the thinking of …

Vedic Maths: Lipstick on a Pig

I was alerted to this video by a pre-service teacher that helps in my room every week. Before this post makes any sense, you should watch the video below. Try to watch the whole thing–I found that task very difficult. As I watched, I found myself becoming increasingly annoyed with the topic. The presenter claims that the problem with current  mathematics is the algorithms that we teach. Ironically, he couples this solution with a boring lecture complete with lack luster audience polling, inadequate wait times, and dry humour. I imagine that a lot of what is wrong with math education …
