IMPACT Mathematics is designed for grades 6-8 with the goal of completing Algebra 1 content by the end of the 8th grade covering Pre-Algebra and Algebra 1 over 3 years. This program has been extensively field tested and has proven to be highly successful in a large urban district with an increase in assessment scores for all students in all three grade levels.
IMPACT Mathematics makes the big ideas of mathematics accessible to middle school students through an emphasis on investigation, problem solving, mathematical understanding, and algebra skills. This edition boasts an improved visual design, updated content, and additional NSF-funded performance assessments. The goal of IMPACT Mathematics remains to help students develop a deep understanding of mathematics with an emphasis on algebra.
