Marjorie Martinelli is coauthor - with Kristine Mraz - of Smarter Charts and the new Smarter Charts for Math, Science, and Social Studies. Their popular blog chartchums keeps teachers in touch with ongoing and relevant classroom issues and ways to use charts as a support. Chartchums is also on Facebook and on Twitter @chartchums! While in schools as consultants with the Reading and Writing Project, the teachers they've worked with have begged them to write a how-to book about the amazing charts they introduce to consulting classrooms. Smarter Charts was that guide, and Smarter Charts for Math, Science, and Social Studies extends that work across the teaching day. She is a staff developer at the Reading and Writing Project where for the past ten years she has lead numerous leadership groups and presented at many national and international educational conferences. Prior to joining the Reading and Writing Project, Marjorie was a New York City public school teacher, a teacher-researcher, and an adjunct teacher at Bank Street College of Education. She has an MA in Early Childhood and Elementary Education from New York University and is a contributing author to Lucy Calkins' Units of Study for Teaching Writing. She is also the author of two Brain Quest Math decks for first and second grade. Marjorie lives in Greenwich Village with her husband Tom, where they raised two daughters, Katherine and Christina.
