Venn diagrams

We learned how to sort information by using a venn diagram. It is two over lapping groups where something could be in one group or both. We made diagrams to show people who were in Wing or boys or both, we sorted odd numbers and those which were bigger than 54 so some were in both. 
We found many people did not know how to recognize and odd/ even number- practice this at home if you are not sure.
