Number Bonds to 10
Number bonds are pairs of numbers that add up to 10. Let's learn them all!
What Are Number Bonds?
A number bond shows two numbers that go together to make another number. Today we are learning pairs that make 10!
Think of it like this: if you have some red sweets and some blue sweets, and there are 10 in total, how many of each could you have?
Part-Whole Model
7 + 3 = 10
Ten Frames
A ten frame has 10 spaces. We fill some with red and some with blue to see number bonds.
6 + 4 = 10
6 red + 4 blue = 10 altogether
8 + 2 = 10
8 purple + 2 yellow = 10 altogether
5 + 5 = 10
5 green + 5 orange = 10 altogether

Key Vocabulary
Number Bond
Two numbers that add together to make a total. Like 3 + 7 = 10.
Part
One of the smaller numbers that makes up the whole. In 3 + 7 = 10, both 3 and 7 are parts.
Whole
The total when you put the parts together. In 3 + 7 = 10, the whole is 10.
Ten Frame
A grid with 10 spaces (2 rows of 5) that helps us see numbers up to 10.
Worked Examples
What goes with 6 to make 10?
Step 1: We have 6 pink squares filled in.
Step 2: Count the empty spaces: 1, 2, 3, 4.
Answer: 4 goes with 6 to make 10. So 6 + 4 = 10!
I have 3 bananas. How many more do I need to have 10?
Step 1: I have 3 bananas. I need 10 in total.
Step 2: Count on from 3: 4, 5, 6, 7, 8, 9, 10. That is 7 more.
Answer: I need 7 more bananas! 3 + 7 = 10.
Use the part-whole model: The whole is 10, one part is 9.
Step 1: The whole is 10. One part is 9.
Step 2: What do we add to 9 to get 10? Just 1 more!
Answer: The other part is 1. 9 + 1 = 10.
