Math Challenge Activity

I built this activity for a group of 120 students from grades 7-10 at a provincial math contest. The problems themselves are a mixture of created, adapted, and stolen. I chose them because they fit fairly nicely into a multiple choice format while still eliciting deep thinking.The puzzle moves forward as follows:There are 10 stations, and 10 problems. Each problem is responsible for giving a unique letter for the final word scramble. Some of the letters are repeated more than once in the final answer (i.e. have a frequency more than one), but no problem leads to the same letter. Each …

Large Whiteboard Project

Group whiteboarding has changed how I teach mathematics. It has also changed how students operate as a community of mathematicians.  Since ordering my first set of large whiteboards, our department has ordered four times again, and given workshops to the division’s mathematics teachers. (For a tour through my whiteboarding history, start here: mini whiteboards) My running motto has become,  “Whiteboards give me more than eight-and-a-half by eleven ideas” This, coupled with the assertion that you can’t expect limitless ideas with limited innovation space, caused me to think bigger. This is the result.  Whiteboard paint from the HomeDepot coupled with ebay’d …
