This activity is based on my favourite show, and it is a mental activity that focuses on whole numbers between 1-100.
The teacher chooses two children to stand in front of the board facing the class. The teacher writes a number between 1-100 on the board (both children should not be able to see it).
Then they take turns in guessing the number. After each guess, the class must respond either ‘higher’ or ‘lower’. The game continues until one person guesses the correct number.
