A description and evaluation are given of the Individualized Mathematics (IM) program. IM is an outgrowth of the work of the Learning Research and Development Center (LRDC) at the University of Pittsburgh. The program has developed and implemented manipulative lessons for primary grade (K-3) students. Like other LRDC programs, this one includes…

The development of the Individualized Mathematics (IM) program is described in this paper. This program, for use in grades K-3, incorporates elements from predecessor Learning Research and Development Center mathematics programs, IPI mathematics, and PEP quantification. It features the systematic use of lessons involving manipulatives in an…

After reviewing the basic principles of instructional design, the author outlines a seventeen-step procedure for the development of mathematics lessons for primary students. The procedure consists of three basic components. The first is concerned with the definition of the unit, and steps in it concern the stating of objectives and analysis of…
