The Kent Mathematics Project (K.M.P.) was an educational system for teaching mathematics to 9-16 year olds. The system comprised task worksheets, booklets, audio compact cassettes and tests. Through the 1970s and 1980s, it was widely adopted in Kent schools, as well as being exported internationally. The system was based on the idea that: mathematical learning should be in terms of levels of concept development and that chronological age should not be the basis of course design.
