Watch our podcasts, "The MLS Number Line" and "Soccer Teams" to see how MLS employs a graphic representation of concepts and procedures to provide a visual, tactile experience. In this method, students

  • discover the concept,
  • construct and experience amounts,
  • connect manipulation with computation,
  • self-correct, and
  • build a mastery of the concept of multiplication and division without rote drills or tricks.

Each number from 2 to 12 is given the same coordinated experience so that students build a context derived and hands-on fluency with multiplication and division.

Also watch our podcast on "The Progress Chart" to see how to use the chart, shown on two of the pages below, to improve performance, not simply measure it.

This book is based on the documented success of "The Best Stuff for Multiplying and Dividing" in raising student achievement scores.
