Lizzy Hull Barnes has taught Math from preschool through Grade 6 in schools around the Bay Area, and supported the learning of adults in Louisiana as well as fellow teachers and coaches in San Francisco. Lizzy asserts that the Common Core has provided all of us a precious window to reframe the question, “What does it mean to be ‘good at math’?” She is excited to lead the work of recapturing mathematics as a multidimensional discipline for all 56,000 students in SFUSD.
