Just as you choose an appetizing entree from a restaurant menu, here are three menus with six activties for CCSS cluster 2.OA.1-4. Use these menus as a tool for differentiating instruction. Allow students at Complete Understanding to choose 1-3 activities during a 1-2 day math period so that you can pull a more intensive group of students at Developing Understanding and reteach or remediate. I am working on all second grade math menus for the CCSS now and should finish by mid September. This is to get you started with your first strand and give you a tool for pausing students ready to move on when you still have students not at mastery.
