Real-Life Math fun Practicing Substitution, interesting Prime Number Discovery!
By Daniel
Algebraic substitution is not very exciting at best. Finding a formula that always generates prime numbers will make you world famous. This task card combines the two math skills into an exciting discovery exercise. Students get to explore the effectiveness of certain formulas in generating primes (while they are doing lots of substitution). Eventually they will see that this exercise is futile, but will hopefully have fun on the journey.

Real-Life Math Fun practice/resource! Slope - A Student activity on Gradient.
By Daniel
It is always a good strategy to review essential skills with your students, and this is right up there with the most essential!
Slope (Gradient) is a very practical real-life experience for all of us - we climb stairs daily and walk up and down very steep and less steep inclines. In this practical, outside activity, students encounter slope first hand and then make sense of the mathematics behind it. Students are then encouraged to think about the real-life applications and implications that slope has in the life of people like the elderly and the handicapped.
