Today I can name the whole and the parts that make it up.

This circle is cut into equal parts. How many equal parts make the whole circle?
2.

3.
48 84. Write < or >.

B Watch me, then you4 min

A box holds 12 cubes. Some are blue and some are red. All 12 cubes together are the whole.

Watch me

The whole is all 12 cubes in the box.

8 blue and 4 red make the 12.

So blue and red are the parts of the whole.

Answers, and what a wrong one tells you

A

1. 4

2. 5

3. <

B

1. 6

C

1. 4 If your child writes 16, they added 10 and 6. The part is taken away from the whole, so the answer is smaller than 10.

2. 6

3. 5 If your child writes 19, they added 12 and 7. Ask whether the not-red part can be bigger than the whole.

4. 13 If your child writes 27, they added 20 and 7. The not-red crayons are the rest of the 20 after the red ones are removed.

D

1. yes If your child circles no, they think size decides what is a part. England lies inside the UK, so it is a part, however big it is.

E

1. Look for: Names a whole and a part inside it, and says why the part belongs inside, not just that it is smaller.

Words to use

Say“Which thing is the whole? Now name the parts that make it up.”

Instead of“Just tell them the answer.”

After the sheet

Tip a pile of buttons or dried pasta onto a plate. Call the pile the whole, then split it into two groups and say each group is a part.

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.
