"The problems on these cards actively engage students and promote conversations about math throughout our classrooms. A key benefit is the variety of visual representations offered in each of the sets. We even use them in our professional development sessions to help reinforce the standards with our teachers! We've found these to be one of the few resources that truly align with the CCSS - both in terms of the Content and the Practice Standards".
