"John Mighton's JUMP program has demonstrated powerfully that, with the right instruction, no one need be left behind in math." -- New York Times John Mighton's innovative JUMP (Junior Undiscovered Math Prodigies) Math program is changing the way math is taught. With these workbooks, parents and caregivers can bring the JUMP program home. The key to the enormous success of the program is a step-by-step teaching method that isolates and describes concepts so clearly that children can not only understand them, but also build up great confidence in themselves and their ability. This workbook includes an introduction that clearly explains the thinking behind the program and follows the carefully designed worksheets used by JUMP tutors and classroom teachers. Royalties from the sales of the JUMP workbooks are donated to the JUMP organization.
