For many adults, mathematics is a vital part of life, but it's easy to forget how we developed the number sense that got us to that point. How did your teacher support your understanding of addition? What was the a-ha moment that finally helped you "get" division? What about figuring out whether something was more than, less than, or equal to something else? For educators participating in the Early Learning Mathematics Initiative (ELMI), these are just the types of questions they are exploring.
ELMI, a professional development program created by the San Mateo County Office of Education and funded by grants from the Heising-Simons Foundation, is a preschool-to-third-grade initiative designed to increase student achievement in mathematics—especially for those students who come from disadvantaged backgrounds.
