1. Collecting Data – Guess!
In this game, students compete in groups of 3 or more.
Taking it in turns, students read out the clues on a card and the first
student in the group to answer correctly gets a point.
If students guess incorrectly they should be out of that round.
Delete unwanted cards.
The cards are arranged to make it easy to guillotine sets for each group.
