Common Core Mathematics Standards Focus – Commutative Property of Addition
Making sense of and understanding mathematics is the foundation of the new Common Core State Standards in Mathematics. It is not enough that kids can compute with numbers – they must understand why those computations work. Enter Number Theory, the part of math that explores numbers and how they relate to each other. At the heart of Number Theory are the properties of number. One of the first ones students will encounter is the Commutative Property of Addition. It states…
