Our Mathematics Projects:

  • are based on intensive research into students’ thinking about mathematical concepts.
  • promote interaction among students to conjecture, prove, refute, and extend ideas.
  • build communication skills such as reading, writing, speaking, and critical listening.
  • engage diverse populations of student learners.
  • address the Common Core State Standards for mathematics, with an emphasis on the Standards for Mathematical Practice, and guiding principles for school mathematics set forth by the National Council of Teachers of Mathematics.
  • improve student achievement.

In Support of this Mission, Our Work Includes:

  • understanding of students’ mathematical thinking and learning.
  • creation of effective curricula and other support materials.
  • promotion of applications of technology.
  • professional development opportunities.
  • support of schools engaged in mathematics reform.

Measure Up

is an elementary grades research and development mathematics project that focuses on developing children’s algebraic thinking, conceptualization, and skills. The mathematics and instructional approach being studied focuses on how students use non-numeric quantities (i.e., length, area, volume, and weight) in a measurement context to develop understandings of mathematics concepts.
