This easy to use, inexpensive and highly effective tool for teaching critical thinking skills really scored with parent testers. Designed to be used specifically with lower elementary students, especially those with less than fully developed spatial skills, the approach is really quite effective. The program gives the student several ways of learning through different activities. One that was mentioned repeatedly was teaching the child to mentally form a three-dimensional object from a two-dimensional image. The program also rewards students after they complete tasks with fun word search puzzles.
