What is Number Decomposition and Why Should I Teach It?

Number decomposition is the ability to break apart numbers. For example, I know that 5 can be broken into 3 and 2. This skill is incredibly important for addition and subtraction. If students know how to break apart numbers, then they will be able to think flexibly with numbers. For example, a child that knows that 5 can be broken up into 3 and 2 will be able to quickly solve 7+5 by adding 7+3 (taken from the 5) to make 10 and then add in the remaining 2 to get 12. This key foundational skill will be built on every year in math.

➕➖✖️➗ What Math Standards Do These Measurement Kindergarten Activities Address? ➕➖✖️➗
K.OA.A.3
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

K.OA.A.4
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.

K.OA.A.5
Fluently add and subtract within 5.
