We love this idea to focus on the MVPs in Math--the Most Valuable Practices in the Common Core-the mathematical practices!! We have 9 cubes for before/during problem solving and 9 cubes for after! One for each mathematical practice and one that mixes them up! 18 cubes x 6 prompts per cube= 108 prompts that get kids thinking and keeps the mathematical practices right in front of us!
We also love our GOAL sheets to Gather Observations and Assess Learning of the practices!
