Ideal for long distances and precise measurements
With this school roller speedometer with counter, children can measure medium and long distances. They develop the ability to visualize lengths and can control estimated lengths. Previously solved arithmetic problems can also be checked with it.


With practical counter
After every meter you hear a clearly audible click. A counter measures the distance traveled up to 99,999 meters. The children drive along a route and count the audible clicks. You compare the length determined in this way with the display on the counter.
The roller speedometer is of course also ideal for physical education. You can easily measure playing fields or racetracks in the hall or on the sports field.


A rubber tire around the wheel ensures accurate measurement and the wheel does not slip on smooth surfaces. You can easily adjust the length of the handle bar.
