Gears is an applet that offers short tasks based on gears. The game applies knowledge, skills and concpets from both maths and engineering/mechanics.
The applet Gears can be found at two different locations in the Primas project and on the RekenWeb. The applet can be used in grade 4-8. We used the applet as preparation for more complex tasks using GearSketch.
Note: The applet does not work on an iPad.
