Five blue plus nine green becomes fourteen. But what happens if each has to get the same number? Now it’ll be both easy and fun to learn to count. In this abacus, there are eight rows with ten balls on each where the children can practice all four rules of arithmetic – addition, subtraction, multiplication, and division. With this counting toy, together with the combination of different colours, you have a fantastic educational tool for teaching the children numbers just as they did when Karin and Carl Larsson themselves were young. On the abacus side, you can find both Carl’s signature and the Kid’s Concept logo burned into the wood.
