Today we're joined by author, educator and PBL advocate Sara Lev, to explain why project-based learning is not only appropriate for our youngest learners, but should be implemented far more often. We cover what it looks like in the early grades, and how principals can lead the way in implementing project-based learning in early childhood.

Sara Lev is teacher on special assignment at the Larchmont Charter School in Los Angeles, and author of Implementing Project Based Learning in Early Childhood. You can find her on Twitter @saramlev.
