Abstract: This series of 12 instructional programs is designed as supplemental instructional materials for junior high and high school mathematics curricula, but additionally can be used for remedial or review work for older age groups. The program provides drill and practice in fractions: adding, subtracting, multiplying and dividing fractions with conunon and different denominators, and concepts of greatest common factors, reducing fractions, least conanon multiples, improper fractions, inverses and reciprocals. The problem difficulty is automatically updated with respect to the student's performance. However, the student may not go on to the next program in the series unless he successfully completes some more difficult problem. After each student answers, the program provides a congratulatory message or a helpful hint. The programs do not maintain record files but do print out student scores at the end of each session. A complete documentation of the package and program listing can be printed on a printer by running, from magnetic tapes, the program-PRINT-using the RSTS monitor.
