### MY PRIORITIES?

This encompasses simplification and paves the way for being able to see how common denominators support working with fractions. Without the understanding of

equivalence, the ability to simplify fractions is unlikely to be applied appropriately: 11 22 = 22 44 22 44 − 11 22 = 11 22 (Seen in Y5 work)

• What does each interval on the number line increase by?

• What number do you estimate the arrow is pointing to? What information helped your estimate?

• Which multiples of one is the arrow in between? Which multiple is it closest to? Is it before or after the unlabelled half-way point between the two known values? What about the quarter and three-quarter points? Repeat for all the arrows.

### 1 litre

• What do you estimate the volume of the liquid in the jug to be? Give your answer in

litres and millilitres.

• Would 0.3 litres be a reasonable estimate? • How do you know it is more that 0.5 litres? • Where would 0.5 litres be on the scale?

Where would 0.75 litres be on the scale? • How can these benchmarks help to make a

• Are all of the scales the same? What is the value of each interval?

• Click to reveal the final location of each arrow. What value is it pointing at? How do you know?

The first arrow has moved one interval, it is pointing at 0.25kg.

Each kilogram has been split into four equal parts. Each interval is worth 0.25kg.
