Description
The Control Chart for the Pythagoras Board (sold separately) is printed on heavy card stock with large, easy-to-read numbers in a ten-by-ten grid. The numbers 1 to 10 appear along the top and left edges, with the interior spaces being filled with the multiples of the intersecting numbers. For example, 24 is printed where 6 and 4 intersect. The chart measures 32 cm (about 12.5" square), and each grid space is 3 cm (about 1") square to accommodate the tiles of the Pythagoras Board.
