Kids Concept, Calculus Board
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.
Warning! CHOKING HAZARD - Small parts. Not for children under 3yrs.

They use alder, lime, beech and maple wod. As of August 2015, they are FSC® (License Code: FSC-C125886) (Forest Stewardship Council) Certified.
By purchasing FSC®-certified products, you contribute to the responsible use of our global forest resources. On the one hand, FSC® achieves this through the definition and testing of environmental and social standards in forest management and, on the other, through the consideration of recycled material, which can be used in FSC®-certified products. Select products are marked on the website and you will find the FSC® logo on the packaging. GRIMMS are pleased that through this step they can take on a little bit more responsibility for our forests and resources and document the efforts externally.
