Decomposing numbers in Kindergarten builds a foundation for understanding number grouping. This carries over into understanding numbers as well as understanding our place value system. So many students see a number for simply the name it holds, like seven. But it is so much more! Truly understanding the number seven, or any number, and flexibly thinking about how to decompose it, will build a foundation for students to know how to decompose numbers in our place value system and bring meaning to the operations we require them to learn.
This is the homework assignment for Thursday night (8/4/16). I just wanted to put it up here in case you had questions about the different parts. Examples are always helpful! :)
