Taking Away within 10

Ages 5–7

You will learn

Take away a number from a number up to 10 and find how many are left.

Before you start

Counting objects to 10, and counting back from 10.

Quick answer

Taking away (subtraction) means finding how many are left when some go away. For example, 5 − 2 = 3, because if you have 5 things and 2 go away, 3 are left.

Let’s learn

Taking away means some things go away, and we find how many are left.

The − sign means take away (we also say “minus”).

Example

🐸🐸🐸🐸🐸 → 2 frogs hop away → 🐸🐸🐸

5 − 2 = 3

A quick trick: count back

  1. Start at the first number. Hold it in your head.
  2. Count back the number you take away.

For 7 − 3: start at 7, then count back 6, 5, 4. So 7 − 3 = 4.

Taking away zero

Taking away 0 means nothing goes away. The number stays the same: 6 − 0 = 6.
