CCSS.MATH.CONTENT.2.NBT.B.9
Explain why addition and subtraction strategies work, using place value and the properties of operations.

The 2.NBT.9 activities that are included in my short answer, centers, printables, and interactive notebooks are similar, but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the ‘Apply new skills’ part of MATH groups.
