The moment students realize they can't just memorize their way through math class is a special moment. The moment students know that they need to "understand' not just remember is one of my favorite moments as a teacher. Today that moment occurred!
My IB Math kids just saw IB questions for the first time... They were almost annoyed that they needed to go look through past notes. Seeing problems that didn't scaffold the 3 steps to get to the answer. Seeing that they will need to THINK!
