Assembling the colourful wooden cogwheels on the board is only half the fun.
Only when the big blue wheel is cranked does it become clear whether the plan has worked or not, are all the wheels turning?
And most importantly, in which direction are they rotating?
The illustrations have been carefully chosen so that the running cogwheels create a "complete artwork": Learning should always be this creative and playful.
Crafted in Germany from sustainable European wood.
