NC.K.OA.4
For any number from 0 to 10, find the number that makes 10 when added to the given number using objects or drawings, and record the answer with a drawing or expression.

Step 1: Lesson Standards & Learning Goals
This standard calls for students to make a group of 10 when given a number between 0 and 10. All of students’ work should be done with objects or drawings, and each decomposition should be shown with either drawings or a verbal expression or when students are ready, an equation.
While NC.K.OA.3 provided students with knowledge of the total and both addends, NC.K.OA.4 is often thought of as a “missing part” or “missing addend” situation since students are given the total (10) and one of the parts.
Students should have multiple experiences exploring how a number can be broken into two smaller numbers using objects such as 2-color counters or snap cubes. Similar to NC.K.OA.3 this standard should be contextualized in word problems.

"Putting together," "adding to," and "join" mean to combine objects or numbers to find a total or sum.
"Taking apart" and "taking from" mean to separate some number of objects from a whole to find a difference.
There are multiple ways to make 10 using addition and subtraction strategies.
