Before learners can write like mathematicians, they need to talk like mathematicians! This interactive session will explore the critical role of oral rehearsal in developing strong mathematical writing skills. Using the TEKS as a guide, participants will learn how to scaffold math discussions, use sentence stems to support verbal explanations, and transition students from speaking their math thinking to writing it down. Discover strategies for incorporating math journals, problem explanations, and reasoning activities that help students confidently express their ideas. Walk away with engaging tools to build a classroom where students talk, reason, and write like true mathematicians!
