Answers are on the grown-up page

Today I can use one addition fact to find the subtraction facts that go with it.

A Look back3 min

1.
6 and make 10.
2.
Ana has 9 pencils. 4 are red. How many are not red?
3.
8 + 2 =

B Watch me, then you4 min

Ella has 4 red beads and 3 blue beads. She knows 4 + 3 = 7. What taking-away facts go with it?

Watch me

4 red and 3 blue make 7 beads, so 4 + 3 = 7.

Take away the 3 blue beads. 4 are left, so 7 − 3 = 4.

Take away the 4 red beads. 3 are left, so 7 − 4 = 3.

Now you

1.
Jo knows 2 + 5 = 7. What is 7 − 5?

C Your turn6 min

Fill in each box. Look for what changes from one row to the next.

5 − 2 =
4.
5 − 3 =

Say it out loud: What stayed the same when the numbers swapped? What changed when you took away instead?

D Spot the mistake3 min

Kit says: “3 + 2 = 5, so 3 − 2 = 5.”

1.
Kit should start with the whole. What is 5 − 2?

E Think deeper3 min

Answers, and what a wrong one tells you

A

1. 4 If your child writes 12, they doubled 6 instead of making 10. Ask how many empty spaces are left on the frame.

2. 5 If your child writes 13, they added 9 and 4. Ask whether the not-red pencils should be more or fewer than 9.

3. 10 If your child writes 9, they only added one. Ask how many counters are needed to fill the frame.

B

1. 2

C

1. 3 + 2 = 5

2. 2 + 3 = 5

3. 5 − 2 = 3

4. 5 − 3 = 2

D

1. 3 If your child writes 1, they took 2 away from 3. Start with the whole, 5, and take away 2.

E

1. Look for: A subtraction fact using 9, 4 and 5, such as 9 minus 4 equals 5 or 9 minus 5 equals 4, with a reason. If your child writes an adding fact, point to the whole, 9. Take one part away from 9 and see what is left.

Words to use

Say“You knew the adding fact already. Can you turn it round to find the taking-away fact?”

Instead of“Just do the same sums again until you get them right.”

After the sheet

Put 10 buttons in two cups. Say the adding fact, then the taking-away fact, and swap the cups.

Tick what your child got right in StudyDen. Anything missed comes back in a later Look back box, so there's no need to redo the sheet.
