My Secret Number

Think of a secret number from 0 to 12 and guess it by asking yes-or-no questions, then swap roles.

  1. Write the numbers 0 to 12 on a piece of paper.

    Ask your child to secretly choose one of the numbers. Then ask him/her a few questions to find out what the number is. Your child can only answer with ‘yes’ or ‘no’.

    You can ask questions such as:

    • Is it even?
    • Is it more than 6?
    • Is it between 4 and 8?
    • Does it have a 3 in it?
  2. Once you have guessed the number it is your turn to choose one and you child should ask the questions.
