We measure LENGTH to know…
• how long things are.
• how tall they are.
• how far apart they are.

We measure LENGTH in…- KILOMETRES (km) to
measure BIG/LONG DISTANCES.
- METRES (m) to measure MEDIUM length.
- CENTIMETRES (cm) to measure SMALL objects.
- MILLIMETRES (mm) to measure TINY/THIN objects.

AREA• We measure an area to know
the occupied SURFACE.
• We measure a BIG area in square kilometres (km2).
• We measure a MEDIUM area in square metres (m2).
• We measure a SMALL area in square centimetres (cm2).

We measure VOLUME to know…
• how much SPACE an object occupies.
We measure VOLUME in…
- CUBIC METRES (m3) to measure BIG occupied spaces.
- CUBIC CENTIMETRES (cm3)
to measure SMALL occupied spaces.
