In maths we have been looking at odd and even numbers. We looked at how even numbers would always show pairs, and each part would have a matching partner. However, odd numbers did not have a matching partner for every part, meaning there was an odd one on its own.
We then tried to guess whether the numicon piece in the mystery bag was an odd or an even number by feeling whether it had a completely flat top meaning that it was an even number as every part had a matching partner or whether it had a bump on the top meaning that it was an odd number as not every part had a matching partner.
