Today I can solve addition stories by finding the total at the end.

A Look back3 min

1.
Count on from 6: 7, 8,
2.
5 + = 10
3.
Write the sign: 14 9

B Watch me, then you4 min

Ella has 3 stickers. She gets 4 more. How many does she have now?

Watch me

First, Ella has 3 stickers.

Then, 4 more stickers come.

Now, 3 + 4 = 7 stickers in total.

Now you

1.
Kit has 2 stickers. He gets 6 more. Now he has stickers.

C Your turn5 min

Fill in each story. Say the first, then and now numbers out loud.

1.
First there are 2 ducks. Then 3 more come. Now there are ducks.
2.
First there are 2 ducks. Then 4 more come. Now there are ducks.
3.
First there are 6 ducks. Then 4 more come. Now there are ducks.
4.
First there are 6 ducks. Then 0 more come. Now there are ducks.

Say it out loud: In each story, which number did you start with, and why?

D Spot the mistake3 min

Ali says: “First there were 4 bees, then 2 more came. So the sum is 4 + 2 = 4.”

1.
How many bees are there now?

Answers, and what a wrong one tells you

A

1. 9

2. 5

3. >

B

1. 8

C

1. 5

2. 6 If your child writes 5, they used the 3 from the last story. Read the then part again: 4 more come.

3. 10

4. 6 If your child thinks the number must change, ask: did any more come? Zero more means the 6 ducks stay.

D

1. 6 If your child writes 4, they have worked out 4 + 0 and missed the then part. Count on from 4: 5, 6.

E

1. Look for: Both are right: 0 + 4 starts at zero and 4 more are added, so the total is 4.

Words to use

Say“Which number was there at the start? Put that one first.”

Instead of“Just add the two numbers you can see.”

After the sheet

Put 6 buttons in a line. Add 2 more. Say: first 6, then 2 more, now 8.

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.
