Grade 1 Addition: Making 10

Learn special number pairs that add up to 10

What You'll Learn

Memorize all number pairs that make 10
Quickly recall 10-bonds (1+9, 2+8, 3+7, 4+6, 5+5)
Use making 10 as a strategy for harder problems

📖Friends of 10

Some number pairs are special because they make 10. Learn these "friends of 10": 1+9, 2+8, 3+7, 4+6, 5+5, and their reverses!

📖The 10-Bonds

0 + 10 = 10, 1 + 9 = 10, 2 + 8 = 10, 3 + 7 = 10, 4 + 6 = 10, 5 + 5 = 10. These are very important to memorize!

💡

Use a ten-frame to visualize making 10. When the frame is full, you have 10!

📖Why Making 10 Matters

Knowing your 10-bonds will help you add bigger numbers later. It is a powerful math tool!

Worked examples

Real problems from the practice worksheets, solved one step at a time.

Example 1
2 + ? = 10
1. A number bond joins two parts to make a whole. The whole is 10 and one part is 2.
2. To find the missing part, take the known part away from the whole: 10 − 2.
3. So the missing part is 8.
Answer: 8
Example 2
? + 6 = 10
1. A number bond joins two parts to make a whole. The whole is 10 and one part is 6.
2. To find the missing part, take the known part away from the whole: 10 − 6.
3. So the missing part is 4.
Answer: 4
Example 3
8 + ? = 10
1. A number bond joins two parts to make a whole. The whole is 10 and one part is 8.
2. To find the missing part, take the known part away from the whole: 10 − 8.
3. So the missing part is 2.
Answer: 2
