'''Developmental Learning Materials'''

Developmental Learning Materials and Jerry Chaffin and Bill Maxwell of the University of Kansas have developed six programs to help your child learn the four basic math operations of addition, subtraction, multiplication, and division. Four programs emphasize-each of the math operations, and two programs develop discrimination between math operations by presenting problems in both addition and subtraction or in multiplication and division. In all six programs, an arcade game format uses colorful graphics and lively action to create an exciting, involving atmosphere for learning.
