fuson@northwestern.edu## Biography

Karen Fuson is a mathematics educator and cognitive scientist whose research focuses on children’s mathematical understanding and the classroom conditions that can facilitate such understanding. Her extensive research has indentified developmental or experiential progressions in children’s understanding of various mathematical domains from PK through Grade 6. She was a member of the National Research Council (NRC) Committee that wrote *Adding It U*p and the NRC Committee that wrote *Mathematics Learning in Early Childhood: Paths Toward Excellence and Equity*. She wrote the chapter on whole numbers for the *NCTM Research Companion to the 2000 Standards* and the introductory chapter for the NRC book *How Students Learn: Mathematics in the Classroom*. Professor Fuson is the author of the K-6 math program *Math Expressions* based on research in the NRC reports and on aspects of international math programsand published by Houghton Mifflin Harcourt. She worked on the Common Core State Standards-Math, the learning progressions for these standards, and the PARCC and Smarter Balance tests.

The titles listed under Projects are links for webcasts Karen Fuson developed to explain the CCSS-Math and show visual supports for student understanding. The examples come from my research-based Kindergarten to Grade 6 math program *Math Expressions* published by Houghton Mifflin Harcourt. Visual supports are very important in the CCSS-Math, so these can help teachers and other educators or parents understand the CCSS-Math and how students can be learning in the classroom. You can move around within a webcast by clicking on the slide titles on the left.
