Length
We measure millimetres with a ruler. We write how long something is by writing the number followed by mm (this is short for millimetres).
Remember that for every centimetre there are 10 millimetres.
1cm = 10mm
=54mm
Measure objects around the house to the nearest millimetre and write down how long they are. What is the smallest and biggest object you can find?
