Fractions
Halves, quarters, eighths, tenths I am learning to identify halves, quarters, eighths and tenths. Fractions are made when something (e.g. a number, set or a shape) is divided into equal parts. This rectangle is divided into eight equal parts. Three parts are coloured red. 3 _ are coloured red. 8 We can write fractions using words and digits. one half =
1 _ 2
one quarter =
Each part of the fraction has a name: The number above the line is the numerator. This tells us the number of parts.
1 _ 4
one eighth =
3 _ 8
An enumerator is a person who counts things e.g. answers in a census or votes in an election.
1 _ 8
one tenth =
1 __ 10
The number below the line is the denominator. This tells us the name of the parts, e.g. halves, quarters, eighths, tenths. It also tells the number of equal parts into which the whole has been divided.
Nom is the French for ‘name’. If you nominate someone, you name them for a certain job or task. Ready to go activity 3.8
