A wooden calculus board with flexible use. Turn the board around to create rows or columns. There are 25 circle-shaped pieces that can represent a singular number, a ten or a hundred. The circles will make it easier to understand the physical connection between the numbers and the actual value. There are also numbers and bricks with division, plus, minus and multiplication signs on them. Made of FSC-certified wood and the brick can easily be stored in the matching textile bag.
