Decompose Numbers (Kindergarten)
Videos, examples, solutions and songs to help
Kindergarten kids learn to 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).
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.
Common Core Standards: K.OA.3 and K.OA.4

Once children have a grasp of the number bonds to ten, they can use their gained knowledge as a strategy for addition and subtraction. Partners to 10
A song to help young children learn the combinations of numbers that add up to 10.
For example,
1 + 9 = 10,
2 + 8 = 10,
3 + 7 = 10,
4 + 6 = 10,
5 + 5 = 10 Number bonds are pairs of friends - number bonds to 10 song

Suggested Learning Target
- I can decompose (break apart) numbers to 10 using objects or drawings.
- I can record the answer using a drawing or equation.
- I know how to separate a number into two parts and understand that there is a relationship between the sum of the parts and the whole
- I know that there are a variety of combinations that represent a given number
- I can begin with the whole when decomposing numbers into pairs. I know that when writing an equation to represent the decomposition of a number, the values on each side of the equal sign are the same (e.g., 7 = 2 + 5)
- I can determine the number to add a given number 1-9 to make 10, and show the answer with a drawing or equation
- I can apply decomposition knowledge and relationship between addition and subtraction to determine the sum or differences of various problems
