Activity 3: Guess my number

This game can be played in pairs, and can be used as a class activity using an interactive whiteboard with teacher versus class or in two teams on a range of digital devices such as an interactive whiteboard, laptop, i-pad, etc.

Purpose

The purpose of this activity is to recognise and order numbers from 1 to 100, and to understand the size of a number.

Activities

  1. Using the hundreds board, say that you are thinking of a number. 
  2. The students guess your number and you say 'higher' or 'lower' (depending on what the number is!) until they guess the right number.
  • The teacher (or a student) is thinking of a number and gives a list of clues such as:
    • it is not even,
    • it is a multiple of 3,
    • it is less than 50 but greater 38...

Students select and eliminate numbers until they have one number left unshaded on the hundreds board.
