K.N.2.1 Compose and decompose numbers up to 10 with objects and pictures.

In a Nutshell

By the end of kindergarten, students should be able to combine groups or pictures of objects to make a number, up to 10. Students should also be able to separate a number of objects into smaller groups.

Student Actions	Teacher Actions
Develop problem solving strategies by using manipulatives to show different ways to make numbers up to 10. Develop a mathematical disposition by exploring different ways to make the same number.	Supporting productive struggle by providing students with tasks and manipulatives to construct representations of numbers. Facilitate meaningful math discourse by allowing students to share the different ways they composed or decomposed a given number.
Key Understandings	Misconceptions
There is more than one way to compose and decompose a number. The number gets bigger when objects are combined. The number gets smaller when objects are separated or removed.	Memorizing math facts.
