Performance of 237 students in ten 8th-grade mathematics classes Was assessed to measure their ability to solve'problems which involve only computation and problems which involve both computation and recognition of the relevance of a particular mathematical idea which is indispensable to-the solution of the problem. Pretests and post-tests focused upon 21 mathematical ideas which are presented in the present.series of IMP (Instructional Math Play) Kits, 16-page pamphlet simulations of a computer programmed to play EQUATIONS like a good teacher rather than like a good player.

Results show that the combination of playing EQUATIONS over two-year period and then working intensively with the IMP Kits for two weeks enables students to apply mathematical ideas (in the sense studied in this experiment) better than any of the other four sets of conditions.
