Why use Discover the Basics math intervention series?
Click on the book images to learn more about each book.

  • NEW!! Equations! - Say goodbye to problems with Algebra. This book enables students—step by step—to understand why equations exist, what equations mean, how to picture them, what stories they represent, and how to work with them. New ideas, skills, and special vocabulary are introduced in simple ways that students understand.
  • Many students move on to the next lesson or next grade with some procedure or knowledge gaps. Turn to Discover the Basics to
    quickly build fluency resulting from understanding and not tricks or drills?
  • Math programs provide students with enrichment and real world application. Go to Discover the Basics to quickly review or reinforce the basics so all students have access to that enrichment?
  • Even with the best of curriculums, too many students are left behind. A
    fresh and economical approach to a specific concept is often needed. Turn to Discover the Basics for proven support for your current math curriculum.
  • Trying again, or trying harder with the same lessons in the classroom, special ed, summer school, or tutoring program, or at home will not produce better results. The fresh approach found in Discover the Basics will produce the results you're looking for.
  • In this series, students construct and experience concepts like why 3.14 is used for "pi" and what it "looks like" to multiply it. They "get the picture." Where needed, the volumes also provide a review of prior skills necessary for the work in that volume.
