Kristine Mraz is coauthor—with Alison Porceli and Cheryl Tyler—of the book Purposeful Play A Teacher’s Guide to Igniting Deep and Joyful Learning Across the Day. She is also the author of the bestselling A Mindset for Learning, as well as (with Marjorie Martinelli) Smarter Charts and 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! Kristi teaches Kindergarten in the New York City Public schools. In addition to writing and teaching, she consults in schools across the country and as far away as Taiwan. She primarily supports teachers in early literacy, play, and inquiry based learning. On the off chance she has free time, you'll find Kristi reading on a couch in Brooklyn with her dog and her husband. You can follow all of her adventures on twitter @MrazKristine or on her blog: kinderconfidential.wordpress.com.
