Grade 2 · Unit 2: Fractions

Fractions of shapes

Equal parts have special names.

A watermelon cut into equal slices.

Cutting fairly

When we cut food to share, the pieces should be equal. Each equal part is a fraction of the whole. Fractions have names: halves, thirds, quarters.

Halves and quarters

2 equal parts: each is a half (½). 4 equal parts: each is a quarter (¼). Two quarters make a half.

Thirds

3 equal parts: each is a third (⅓). The bottom number tells how many equal parts. The top number tells how many we are talking about.

Equal or not?

Parts must be equal in size to be fractions. Two quarters (2/4) cover the same space as one half. More parts means each part is smaller.
