Wanna be in my gang?
A great little game to get kids thinking about types of numbers.
Think of a particular type of numbers that you want the pupils to guess. This could be square numbers, cube numbers, triangle numbers, even numbers etc… Tell the pupils that they need to guess a number between 0 and 100. If their number matches your hidden criteria then you say “you’re in my gang”. If the number doesn’t match your hidden criteria then you say “you’re not in my gang”. The pupils keep guessing until they work out what type of numbers you are thinking of.
Big thanks to Nicola for this great idea.
