Identifying the number of equal or unequal parts in a whole

Maths

Secure identifying a whole and the parts that make it up

Secure identifying equal parts when they do not look the same

Review explaining the size of the part in relation to the whole

Review constructing a whole when given a part and the number of parts

In this unit pupils will identify equal parts when they do not look the same related to equivalence. They will construct a whole when given a part and the number of parts. In the future unit pupils will compose and decompose quantities made of whole numbers and fractional parts.

In the prior unit pupils used repeated addition of a unit fraction to form a non-unit fraction. They compared non-unit fractions with the same denominator. They added and subtracted fractions with the same denominator. In this unit pupils will identify equal parts when they do not look the same related to equivalence. They will construct a whole when given a part and the number of parts.
