The program supports students' understanding of key math concepts and skills and covers a range of mathematical content across grades. The curriculum focuses on questioning strategies, problem-solving skills, embedded assessment, and exercises tailored to students of different ability levels. It provides explicit problem-solving instruction, hands-on activities, and opportunities to extend students' mathematical understanding through reading and writing connections. One study of "Scott Foresman-Addison Wesley Elementary Mathematics" met the What Works Clearinghouse (WWC) evidence standards. (Resendez & Manley, 2005) was a randomized controlled trial included more than 700 students in second and fourth grades, in a mix of urban, suburban, and rural schools in Washington, Wyoming, Virginia, and Kentucky. Resendez and Manley (2005) reported no statistically significant effects of the "Scott Foresman-Addison Wesley Elementary Mathematics" program.
