Welcome to the ThinkMath! Website

Think Math! is a comprehensive kindergarten through fifth grade curriculum that provides high-quality mathematics for all children.

This pilot and field-tested curriculum was developed by Education Development Center, Inc. (EDC) in Waltham, MA under the working title Math Workshop, with support from the National Science Foundation.

Think Math! does not pit skill against problem solving. Rather, it builds computational fluency through plentiful practice in basic skills as students investigate new ideas and solve meaningful problems. Lessons provide glimpses of ideas to come, letting students build familiarity and develop conceptual understanding as they apply, sharpen, and maintain skills they already have.

Think Math! K-5 curriculum and Think Math! content-based professional development provided by EDC address the goals of the American Recovery and Reinvestment Act (ARRA) of 2009.

  • Think Math! is aligned with NCTM’s Principles and Standards for School Mathematics (2000) and features ongoing assessments to measure student understanding and progress.
  • EDC offers intensive, capacity-building training to ensure teachers have the knowledge and tools to develop students’ mathematical thinking and effectively implement Think Math! in the classroom.
