Divide participants into groups of 4–6 people. Each group gets a defined area of at least 2×4 meters.

The leader says or writes an arithmetic problem on a whiteboard/board. The groups must collaboratively find the answer and 'write' the solution on the ground by forming the numbers with their bodies.

Example:

If the leader says 2×5, the participants must collectively form the number 10 with their bodies.

If there are many in the group, the leader can also ask them to create the 'equals' sign (=).

Variation

Let each group prepare their own arithmetic problems.

  • First, one group 'writes' their arithmetic problem with their bodies.
  • Then the other group must 'write' the solution with their bodies.

The exercise can easily be adapted for older students by providing problems at their level, for example with:

  • decimal numbers
  • fractions

Then the groups can be challenged to 'write' both more complex numbers and symbols.
