Mastering Make-a-Ten

🎯 What Will We Learn Today?

Making a ten is the secret superpower behind fast mental math! Today we'll learn number pairs that add up to 10 and use them to make addition and subtraction way faster.

📚 What Are Number Bonds to 10?

Number bonds to 10 are pairs of numbers that add up to 10:

1 + 9 = 10

2 + 8 = 10

3 + 7 = 10

4 + 6 = 10

5 + 5 = 10

Memorize these and math gets so much easier!

🎮 How Making a Ten Speeds Up Addition

Solve 7 + 5

7 needs 3 more to make 10 → borrow 3 from 5

5 − 3 leaves 2

10 + 2 = 12

So: 7 + 5 = 7 + 3 + 2 = 10 + 2 = 12

Solve 8 + 6

8 + 2 = 10, 6 gives away 2, 4 left over → 10 + 4 = 14

💡 Making a Ten with Subtraction

Solve 16 − 7

Split 16 into 10 and 6

Can't take 7 from 6 → take 7 from 10 = 3

3 + 6 = 9

Or: 16 − 6 = 10, then 10 − 1 = 9
