When something is equivalent, it is equal in value.

When we can convert, we change the unit of measurement between millimetres and centimetres but the value remains the same.

Converting between centimetres and millimetres

Maths

In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures including comparing and using mixed units In the future unit pupil will learn perimeter as the distance around the edge of a 2D shape They will learn perimeter is measured in units of length found by counting units and by calculating by adding the side lengths of a 2D shape

In the prior unit pupils chose, used and compared appropriate standard units to estimate and measure length/height, mass, temperature, capacity to the nearest appropriate unit. In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures, including comparing and using mixed units.

Measuring length and recording in tables

When we change the unit of measurement between millimetres and centimetres, we {{ }}.
