SIDES CHECK STRATEGY

What is it?

SIDES Check is the embodiment of all problem-solving strategies, broken down in a way that reminds kids the process of how to solve problems.  It’s NOT a checklist.  It guides thinking.  To solve any problem, you need to name the problem, identify what you need to try to solve it, make a plan using that information, and then attempt to solve it.
