Maths: sorting diagrams

We used Venn diagrams to sort letters into groups for homework. Those of us who took care, and looked carefully at each letter without trying to guess quickly, managed to put all the letters into the correct places. Well done!

Remember: if a letter goes in both sets, it goes in the middle. If it goes in neither set, it goes outside.

Finally we revised our earlier work on Carroll diagrams. Nothing goes outside a Carroll diagram. Everything fits in somewhere. We have to think about each question separately. Is the letter capital? If so, it goes on the left side. If not, it goes on the right side. Is the letter a vowel? If so, it goes at the top. If not, it goes at the bottom. Lastly we put the two answers together. For example, a capital vowel would go at the top left.


Here is another Carroll diagram with different titles. Where would a capital J go on the diagram? Think carefully!
