Wilma Hashimoto is one of the AIMS Center’s Research Associates working on a project focused on the pre-school years and how children build their earliest understandings of mathematical thought. We focus on how early understandings of mathematics affect learning trajectories can influence success in later schooling. We also examine what sort of things can and should comprise early mathematics instruction. A point about creating “intentional” mathematical learning opportunities is also examined. We get to talk about Spew too!
