As it was the last lesson in the sequence for the below objective:
Convert between different units of metric measure [for example, km and m; cm and m; cm and mm; g and kg; l and ml]
we were working in groups to match measures, written in different units of measure, proving what we knew! There are so many different measure conversions for them to recall, metres to centimetres and to millimetres and grams to kilograms etc. We relied on a WAGOLL to check our answers. The trickiest part was succinctly writing how we proved it.
