Welcome to the new and the 3rd of our Problem Solving Badges! This challenge is all about meeting new people. As always, try and solve this problem creatively, perhaps in the form of a video explanation in groups.
  1. Task 1 Handshakes

    In September I joined a new school, there were lots of children in the class I didn't know. To get to know them I shook hands with then all! There were 14 unfamiliar children in total. How many handshakes was that?

    We then all shook hands with each other. How many handshakes was that?

    Is there a pattern depending on how many people are in the class? What if all of the children in the class decided to shake hands (31 children) - how many handshakes would that have been?
