The number line

Number line 12.2 meters long
 Use this number line to do psychomotor movements, long jumps and mathematics! On this number line, it is possible to work on jumps of 2, 5 and 10. It is also possible to ask students to make movements based on additions or subtractions.
 For example: Start at 53, move forward 10, move back 5, and move forward 8 (53+10-5+8).
