Gregory and Oleksandr have built on the arc midpoint resource and the proof of the arc midpoint formula by constructing an algorithm for finding the coordinates of the midpoint. It is hoped that teachers of high school Mathematics and Computer Science will use these resources to enrich the teaching and learning in both subject areas.

The atlatl and dart, the predecessor to the bow and arrow, was very important in the lives of Aboriginals in Saskatchewan and all over the world up until about 2000 years ago. Experiment based lessons allow students to learn about the science behind the weapon system that put humans on top of the food chain. Subject integrated lessons for grades 4-12 in the areas of math, science and social studies based on Saskatchewan curriculum objectives.
