Subtraction to 20 asks children to take away across ten, such as taking 7 from a teen number, which is harder than staying inside the tens. Useful strategies are counting up to find the difference, or splitting the 7 into 5 and 2 and taking them away in steps. Recall of addition facts underpins all of it. Grade 1 subtraction within 10 comes before, and 2-digit subtraction follows.

Choose 12 problems when a child is tired or anxious, and 30 only to test fluency. Switching on Missing number mode turns each question into an addition puzzle, which many children find easier to reason about. Keep Compact layout for review days. Alternate this page with the addition one to keep both facts families fresh.

What is a good way to subtract across ten?

Break the number you are taking away. To take 7 from 12, take 2 to reach 10, then take 5 more. It relies on knowing the pairs that make 10, so practice those first.

How can counting up help with subtraction?

To solve 12 minus 9, count up from 9 to 12 and note the gap of 3. This works well when the numbers are close together and avoids counting backwards, which many children find error-prone.

Is 20 problems too many for a seven year old?

For most it is fine, around ten minutes. If the child rushes or tires, switch to 12 problems. A shorter page done well is better than a long one done carelessly.
