A Modular, Targeted Program Mathematics Navigator is an easy to use, flexible program that is comprised of 20-day modules of instruction on discrete topics. Students are placed in the appropriate module based on their performance on high-stakes tests, teacher recommendations, or the included diagnostic screener. Once students demonstrate mastery of a targeted concept, they exit the program—and they are better prepared to participate with new confidence in their regular math class.
