In our Mastering Number sessions, we have begun to learn about odd and even numbers. Odd numbers are numbers which, if you represent them and pair them in 2s, will have an odd one out. If you pair up even numbers, they will all have a pair and an ‘even top’. We loved watching Numberblocks explain this to us, and then represented different numbers using counters and tens frames, saying if the number is odd or even.
