Method and apparatus for teaching mathematics

摘要: An improved method of teaching mathematics which enables students to take an active and enjoyable role in their own learning via interactive puzzle is disclosed. In the preferred embodiment, each ten digits, zero through nine, “hidden” within one value positions ( 52 ). Students must deduce position by forming sums, differences, products, and/or quotients positions. Freedom selection operations provides for individualized approaches solutions, interplay values promotes number sense. Mathematical reasoning intrinsic puzzle. Programmable settings 72 ) allow teacher modify puzzle, including substituting more challenging place digits 98 ), supplying complex functions 106 four elementary arithmetic operations, adjusting format answers.
