A complete Algebra curriculum by the end of eighth grade This exciting new program, developed in cooperation with Education Development Center, Inc., makes mathematics accessible to more of your middle-school students. They will spend less time reviewing topics from previous grades and more time progressing carefully and successfully toward the completion of Algebra 1 by the end of grade 8. Informal-to-formal concept development, designed specifically for middle school students, ensures that students build necessary skills and develop conceptual understanding.
