EdReports.org, an independent non-profit, has released free, web-based reviews of current K-8 math instructional materials. The teacher-led process raised good questions for textbook consumers about the alignment of current options, reviewing popular textbooks to see whether the math content aligned to the Common Core.
Check out the reports for their analysis and as you approach the process of
choosing or adapting instructional materials in your school and
district for the coming year, consider using an alignment-focused tool such as
the Instructional Materials Evaluation Tool.
