The whole is 1,000.

500 and 500 make 1,000.

500 is 5 hundreds, so 5 + 5 makes 10 hundreds.

Now you

1.
600 and make 1000.

Count along the number line. Each row changes one thing.

1.
How many hundreds make 1,000?
2.
How many hundreds make 500?
3.

Answers, and what a wrong one tells you

A

1. 70

2. 1

3. 460

B

1. 400 If your child writes 1600, they have added 600 to 1,000. Ask what is left of 1,000 after the 600 is taken away.

C

1. 10

2. 5

3. 10 If your child writes 1, they have counted the hundreds again. Count along in steps of 10 to find the tens.

4. 20 If your child writes 2, they have divided 200 by 100 and stopped. Each ten is 10 ones, so count tens in steps of 10.

D

1. 100 If your child writes 10, they have counted the hundreds, not the tens. Each hundred holds 10 tens, so 10 hundreds hold 100 tens.

E

1. 10 If your child writes 100, they may have filled the gap to the next hundred. 900 + 90 is 990, so count on from 990 to 1000.

Words to use

Say“How many hundreds fit in 1,000? Let's count them out loud.”

Instead of“Just learn that 1,000 is a big number and move on.”

After the sheet

Lay out ten buttons and call each one a hundred. Then ask how many tens and ones you could break the pile into.

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.
