发明名称 Apparatuses and kits for teaching mathematics
摘要 A method and apparatus of teaching mathematical problem solving includes using a series of containers, each consisting of an inherent problem requiring the use of mathematical skills for solution. The series of containers meets all conditions for the teaching of mathematics as recommended by the National Council of Teachers of Mathematics in their 1989 document "The Standards". The complete solution satisfying "The Standards" for each container ordinarily takes a period of days. A kit consisting of such containers is disclosed.
