Mathematical boats. Counting material from 1 to 20.
Twenty -two -tone wooden chips in four wooden “boats” are made of plywood painted with the method of UV painting and laser cutting, on the one hand in red, on the other blue.
Four boats are made of beech, on one side of the boat there are nests for five two -tone chips, on the other side the numbers are depicted.
With chips, you can do simple and understandable things: put them in boats or take them out of it, turn it over or sort by color. Placing bright chips in the cells of “boats”, the child “playfully” masters arithmetic, and sometimes discovers interesting mathematical patterns for himself.
