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

  • 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.

What Your Colleagues Say
"Math gains were incredible! All kids in summer school were "far below basic" in math -- less than the 19th percentile. 100% of our math class students left summer school knowing how to multiply and divide in the 90th percentile and above. Awesome. What a gift! I absolutely love your materials!"
