In an age when distance learning has become part of the "new normal," educators know that rich remote math teaching involves more than direct instruction, online videos, and endless practice problems on virtual activity sheets. Using both personal experience and those of teachers in real K-grade 12 online classrooms, distance learning mathematics veteran Theresa Wills translates all we know about research-based, equitable, rigorous face-to-face mathematics instruction into an online venue. This powerful guide equips math teachers to do the following: (1) Build students' agency, identity, and strong math communities; (2) Promote mathematical thinking, collaboration, and discourse; (3) Incorporate rich mathematics tasks and assign meaningful homework and practice; (4) Facilitate engaging online math instruction using virtual manipulatives and other concrete learning tools; (5) Recognize and address equity and inclusion challenges associated with distance learning; and (6) Assess mathematics learning from a distance. With examples across the grades, links to tutorials and templates, and space to reflect and plan, "Teaching Math at a Distance" offers the support, clarity, and inspiration needed to guide teachers through teaching math remotely without sacrificing deep learning and academic growth.
