step 1 of 6
Last week at the allotment, Leo and Mia shared the strawberries onto plates. Every plate got the same. Today there is one apple left in the basket, and two friends.
One apple cannot go on two plates. What can you do?
What Is a Half?
Recognise, find, and name a half as one of two equal parts of an object, shape, or quantity
What a learner can do afterwards
- Fold a shape into two equal parts and identify each as 'a half'
- Find half of 8 objects by sharing into 2 equal groups
- Identify whether a shape has been divided into halves or not (equal vs unequal parts)
1 · Read
Halves are two equal parts. Split something into two same-size pieces. Each piece is called a half.
Tap to shade 1 of the 2 parts.
Both parts must be the same size. If one piece is bigger, it is not a half. Halves always match exactly.
Tap each apple and count out loud.
Good to know
To check for a half, look at both parts closely. Do they match in size? Then it is a half.
A half is one of two equal parts, always the same size.
