LEARN ABOUT IT To solve some problems a helpful strategy is LOGICAL REASONING.

The Canterbury Dance Festival presented dances from many different countries. 32 children joined in the dances. 19 danced the Welsh Dance and 15 danced the Scottish Dance. How many children danced in both dances?

I'll draw a Venn diagram. I'll put 19 counters inside the Welsh circle. I'll put 15 counters inside the Scottish circle. To do this with only 32 counters. I must place 2 counters so that they are inside both circles. 2 children danced both dances.
