» Community Math Program

Modeled after Attallah College’s Kathleen Muth Literacy Center, the Community Math Teaching and Learning Program integrates teacher education training and community tutoring.  The community program gives Chapman students opportunities to practice research-based math instructional strategies while providing free mathematics tutoring to students in the community.

Embedded within Chapman's five-year, accelerated MACI (Master of Arts in Curriculum and Instruction) teacher education program, the math program serves local families and youth while giving Chapman graduates hands-on practice.

The primary goal of the program is to learn by doing for the Chapman students and the K-12 children.

The Community Math Teaching and Learning Program is made possible in Spring 2021 by the generous support of the Klein Family Foundation.

Siena Kemp

Math Supervisor
Siena Kemp’s 10+ years of experience working with children, coupled with her training in UDL (Universal Design for Learning), systems thinking, complex instruction, and CGI Math have led her to a truth that is evident the moment you walk into her 6th grade classroom, bubbling with excitement and noisy with rich conversation: that math is learned best in the presence of joy. Siena not only sees the mathematical brilliance that is within every child, but through her intentional deconstruction of the walls of intimidation and exclusivity that are built up around mathematics before children even enter school, Siena helps children to see the mathematical brilliance within themselves.
