Grade 1

What is a part?

part

One piece of a bigger whole.

For example

Break the bun in two and each part is the same size.

In Grade 1

Children break a whole into parts and put it back together, so part and whole are always met as a pair.

Watch out for

Children often think any piece counts as a fair part. Parts only earn a name like half when every piece matches.

Say it at home

When you break something in two, ask whether the parts are the same size or not.
