Mind Jerky - Problems you can CHEW on for a while
Solving problems is fun! We love a good challenge that causes us to really think. Being able to apply mathematical understanding to real-world contexts (and sometimes to playfully ridiculous ones) brings everything alive. Don't worry future, we'll be ready to solve your problems!
Below you can enjoy problems composed by students as part of the regular morning routine. One student per day writes a problem, then someone else solves it, sharing their strategy with the rest of the class. This leads to some very stimulating discussions as students develop and deepen their understanding together.
