Abstract
A mathematical teaching apparatus comprising block elements having a front and back side, including indentations and protrusions to allow the blocks elements to stack. The block elements are inserted into a block element sleeve, which hold 10 stacked block elements. Block element sleeves are also stacked and inserted into a large sleeve, which holds 10 stacked block element sleeves. Block element sleeves also include indentations and protrusion to allow stacking. All three units are counted by counting devices which provide an indication of the number of units of each type present. The counting devices also signal when 10 block elements or 10 block element sleeves are inserted, signalling to a user that the blocks or sleeves should be inserted into a next-larger size sleeve. The mathematical teaching apparatus allows children to learn the concepts of number magnitude, addition and subtraction, including carrying and borrowing. A computer program implementing these ideas can also be used to present the mathematical concepts.
