We're continuing with finding a fraction of a set of objects or an amount today, so we're building on yesterday's work of finding 1/2, 1/3, 1/4, 1/5, 1/6 etc. but now changing the numerator.

When this happens, for example, 'find 2/3 of 18'. You have to look at both the numerator and denominator.

Look at the denominator  to find how many equal groups, and the numerator  to find how many of those groups you need to count.

For example;

Find 2/3 of 18.

Divide 18 into 3 groups (denominator is 3)

Then choose 2 groups (numerator is 2) to find your answer.

So 1/3 of 18= 9, 2/3 of 18= 12 and 3/3=18.


Again, you can watch the white rose teaching video and complete the attached work on the right hand side of the video, or do it practically at home and record in your home learning book.
