Year 4

Our first math challenge was a countdown conundrum. 4 small and 2 large numbers were randomly created and a target number set. The children then worked independently to get as close to the target number using any of the 4 operations that they needed, without repeating any number.

The second challenge was to work out how many possible aliens there could be if only the amount of alien's legs were counted. The challenge total was 52, with Zios having 3 legs and Zepts having 7. Here are the children's workings out.
