This activity is best played in pairs.
Child A thinks of a number. They state a range in which their number can be found, e.g. “My number is between 0 and 100” or “My number is between 250 and 500”.
Child B has to ask Child A questions in order to find out the number, but A can only reply using “Yes” or “No” answers.
For example…
- Child A: My number is between 50 and 150
- Child B: Is it less than 100?
- Child A: Yes.
- Child B: Is it more than 75?
- Child A: No.
And so on…
The children could count the number of questions that they each asked, seeing who found the mystery number in the lowest number of questions.
