The Critical Thinking Company has been publishing award winning products to help students of all abilities achieve higher test scores for over 50 years. The contents of these bundles were carefully selected by The Critical Thinking Company to ensure coverage of material tested on the Iowa Test of Basic Skills (ITBS). Each activity requires students to analyze, synthesize, and apply what they learn. The more students think about what they are learning, the more students understand what they are learning. There is no need for an expensive tutor with a resource like one of these bundles.

The Critical Thinking Company is recommended by Mensa, Learning Magazine, The Well Trained Mind, Dr. Toy, Creative Child Magazine, and used by Sylvan Learning Centers, Club Z In-Home Tutoring, leading U.S. public schools, and gifted and talented programs in 57 countries throughout the world. They guarantee better grades and higher test scores.

We at Think Tonight had no control over the contents of these bundles. The Critical Thinking Company does not permit discounting of individual titles and to be able to offer bundles at a discount we are required to offer their products exactly as bundled by The Critical Thinking Company (no substitutions permitted). In addition to the bundles below we highly recommend the Spectrum Test Preparation and Spectrum Test Practice Series.
