This video offers a glimpse into two classrooms as teachers Kassia Omohundro Wedekind, author of Math exchanges, and Rachel Knieling facilitate small-group math meetings with their kindergarten and 1st grade students. See what small-group math exchanges look like, sound like and feel like, and hear from Kassia and Rachel as they plan, teach and reflect on their math conferences. How did you solve that? addresses issues such as: Establishing a strong math workshop in which small-group math exchanges are central, Assessing students' mathematical understandings, Grouping students for math exchanges, Planning effectively and efficiently for math exchanges, Crafting teacher language that supports (but doesn't take over) student thinking, Encouraging student talk, Choosing problems and numbers Knowing what to do when math exchanges take an unexpected turn. In a special feature, Kassia answers teachers' most commonly asked questions about guiding young mathematicians in small groups, from how to get started, to thinking about future goals for students. Join her in her classroom as she skilfully guides young learners to make sense of problems and persevere until they've found a solution. About the author Kassia Omohundro Wedekind is a math coach at Bailey's Elementary School for the Arts and Sciences right outside of Washington, D.C. "I am someone who likes a lot of change in my teaching life," admits Kassia. The road to Bailey's took her to central Virginia where she taught English for Migrant Education in migrant camps. "I learned a lot about teaching, immigration and migration issues, and apple and peach orchards," she says. Kassia then decided that she wanted to work with children so she taught ESOL in a couple of different schools before teaching second and third grade at Bailey's. After several years at Bailey's as a classroom teacher she became a math coach and works mostly with teachers and students in kindergarten and second grade.
