1 Measuring to the nearest ½ cm or mm.

2 Measure the length and width of this shape to the nearest ½ cm The length is the longest side The width is the shortest side

3 Measure the length and width of this shape to the nearest ½ cm 1. Measure the length 2. Measure the width The length is The width is 9½ cm 4½ cm

4 Measure the length and width of this shape to the nearest ½ cm 1. Measure the length 2. Measure the width To the nearest half cm, the length is To the nearest half cm, the width is 8½ cm 3 cm What if they are not exact sizes?

5 Measure length and width to the nearest millimetre Most of the time, we use this side of our rulers for measuring. If we turn them the other way round, we have millimetres Notice that the numbers go up in 10s.

6 Measure length and width to the nearest millimetre Here is a close-up of the millimetres markings 0 0 Each 10 millimetres is marked.Each millimetre is also marked. This means that we can be more accurate with our measuring. We can now measure objects to the nearest millimetre!

7 Measure the length and width of this shape to the nearest millimetre 1. Measure the length 2. Measure the width The length is The width is 92 mm 46 mm
