Asco & Celda is a French company for the manufacture of pedagogic materials for children from 2 to 12 years. Besides other materials (e.g. garden tools, kitchenware...) it produces "the table of pythagoras". This 3d puzzle consists of 100 wooden sticks to visualize the multiplication table. The heights of the sticks match the 10*10=100 combinations of products of two numbers from 1 to 10. Arranged in a square slot, one visualizes the products from 1*1=1 to 10*10=100.
