Today we will be learning: how to compare and order fractions how to use, read and write words to do with fractions.
Mental Activity We are going to practise doubling. Work out the answer before it appears. Double 11 22
Double Double Double 17 34
Now we are going to practise multiplying by 4 quickly. We do this by doubling then doubling again. Work out the answer before it appears. 11 x 4 44
9 x x x 4 80
15 x x x 4 56
Main Activity Today we are going to learn to order fractions.
Here is a piece of paper. 2 If it were folded once in the middle, how many equal parts would there be?
What would each part be called? One half or 1212
If it were folded in half again, how many equal parts would there be?
What would each part be called? One quarter or
If the paper were folded in half again, how many pieces would there be? 8
What would each piece be called? One eighth or 1818
Here are two fractions Which one do you think is bigger? Why?
One half is greater than two eighths
This symbol means “is greater than”. The big end faces the biggest number.
Group Work Fold a strip of paper in half, then in half again and so on. Complete a chart to show the fractions that you have made. Make up some equivalent fractions. Order fractions using ‘greater than’ and ‘less than’ symbols.
