Preparation

  • Print the floor plans in the hallway (A4 size) and hang them somewhere in the hallway.

  • Read through the answers beforehand.

  • Note: The building has two floors.

Answers to poster 1: ground floor

Number of students

5 x 1 = 5

6 x 2 = 12

13 x 5 = 65

Total: 82

Route

On the A4 sheet in the hallway, the route is approximately 37 cm.

The scale is 1:250.

So the actual route is 9250 cm, or 92.50 meters.

A different answer is valid if the drawing and calculation are correct.

Poster 2: 1st floor

Number of students

6 x 1 = 6

6 x 2 = 12

11 x 5 = 55

Total: 73

Route

On the A4 sheet in the hallway, the route is approximately 20 cm.

The scale is 1:250.

So the actual route is 5000 cm, or 50 meters.

A different answer applies if the calculation is correct.
