Handshaking maths!

Class 6 used excellent problem solving skills to solve a very polite maths problem today!

The children worked in groups. This is the initial problem that was set for them:

We have 30 children in this class. If everyone shook hands with everyone else, how many handshakes would there be in total?

We started by using real children to test for one, two, three and four people shaking hands. The children then used drawings to work out five – ten people shaking hands.

It was very complicated and we had to work carefully so that we didn’t count too many handshakes or repeat them!

Eventually some of the children spotted a pattern or rule in their results and worked out how many handshakes there would be between our class of 30 children! If you would like to know the answer, please come to Class 6 to find out!
