What are the best ways to assess student learning in mathematics? The University of California at Berkeley and the Shell Center for Mathematics Education at the University of Nottingham have teamed up to create a wealth of free resources to help mathematics instructors engage in both formative and summative assessments. On this website, math instructors can access a number of assessments designed for middle school and high school mathematics classrooms. These resources include almost 94 tests, 100 lesson plans (or Classroom Challenges), and a number of summative assessment activities (or Tasks), accompanied by rubrics. All of these materials are sorted by grade level (6-12) and are available for download in PDF format. These materials are designed to meet Common Core State Standards for Mathematics (CCSSM). In addition to these ready to use classroom resources, the Mathematics Assessment Project also includes a handful of modules for teacher professional development.
