This report summarizes the first two years of study at the Elk Grove Training and Development Center. The initial program was designed to improve mathematics instruction through the use of a non-graded multi-media approach utilizing laboratory team teaching. Achievement test summaries indicate that K-5 students instructed in mathematics through this program have achieved at or above grade level on standardized tests. The author concluded that the students became truly involved with this approach to learning mathematics, but the teacher had to have assistance in the lab, time for planning and inservice training, and a sincere commitment with the program. This work was prepared under an ESEA Title III contract. (RS)
