Successful comprehension of algebra, geometry, statistics, and probability is dependent on students’ fundamental understanding of important mathematic concepts in Pre-K through 3rd grade.  This math portal was designed in collaboration with agencies, institutions and mathematicians to broaden access to quality, evidence-based practices.  We invite teachers to explore the site and find toolkits with the latest best practices and supports for implementing common core state standards. Families are encouraged to find activities to support math skills and information to better understand new approaches to math.
