The MATCh (Materials and Activities for Teachers and Children) project began with the premise that real objects and activities were essential to expand and improve the teaching and engagement of students in a variety of subjects. The MATCh program created units of study in which everything necessary for a two- to three-week exploration of the subject was packaged together in boxes for use in classrooms.  Each box contained real objects as well as films, pictures, recordings, models, maps, and books, along with curriculum instructions and guides.
