Corrective Mathematics is a remedial system that solves a wide range of problems for struggling older students, even when other approaches have failed. Explicit, step-by-step lessons are grouped into separate modules that may be taught separately or concurrently to customize instruction for particular student needs. The program contains modules for addition; subtraction; multiplication; division; basic fractions; fractions, decimals, percents; and ratios and equations. Upon completing one or more modules, students are equipped with the basic strategies they need to access conventional math instruction successfully.

Corrective Mathematics is typically needed for older students whose math performance is characterized by a weak grasp of the basics, a lack of facility with math facts, inaccurate computation, and a lack of problem-solving strategies. The program is effective for students with poor attention and poor recall of directions, or for others who meet the criteria for special services. With a high success rate, frequent teacher feedback, and built-in opportunities to earn reinforcement throughout each lesson, even students with histories of failure remain motivated and on task as they master fundamental math concepts and skills.
