We investigated number systems in history. The three we found the most interesting were Egyptian, Babylonian and Mayan. In teams we had to put together a jigsaw of each number system and work out what the symbols would be in our number system.

Once we worked out each number system we had a go at some simple adding and subtracting calculations using the different number systems. I think we are all happy we use 1,2,3,4😅.
