This activity could be given to students with little introduction from the teacher. Alternatively, the
game could initially be played between the teacher and a large group of students. It is important
that students are encouraged to think carefully about the numbers they choose and that the
teacher focuses on the students’ mental skills. Most benefit is obtained from the activity when
students are playing together in small teams, discussing their choices of a number to multiply by.

At the end of the activity, students’ strategies should be discussed and compared.
Further Ideas
• Play the game with different target numbers. For example, students could multiply or divide
a random number to reach a target of
1
.
• The first player multiplies a random number to aim for a target of
1
00. The second player
then multiplies this answer to try and get even closer to
1
00. The player who gets the
calculator to display a number between 99 and
1
0
1
wins.
