Fractions

fractions for one quarter, one half, three quarters; a pizza showing thirds; a pie showing sixths

In What Your Year 2 Child Needs to Know, we learnt the fractions for ¼ (one quarter), ½ (one half) and ¾ (three quarters).

A fraction has a top number and a bottom number. The bottom number tells how many equal parts there are. The top number tells how many equal parts you are talking about. For example, in the first circle in the top left, one part is orange. How many equal parts are there? 4. How many parts are orange? 1. So this fraction shows ¼ (one quarter).

If something is divided into three equal parts, each part is one third, which in numbers is written as 1/3. This pizza is divided into three equal slices. Each slice is one third. If you were very hungry and ate two large slices, what fraction of a whole pizza did you eat? You ate two thirds.

I have baked an apple pie, and Josie has already eaten a slice of it! How many equal slices are there in this pie? 6. What fraction of the pie has Josie eaten one sixth.

You can also use fractions to talk about parts of a group. For example, there are ten girls in the class. Seven of them are in the football team. What fraction of the girls in the class are in the football team? Seven tenths of the girls in the class are in the football team.

In What Your Year 3 Child Needs to Know, we learn more fractions so you will know one half, one third, one quarter, one fifth, one sixth and one tenth. In Year 3 learn about remainders in division, too, and in Year 4 we learn even more.
