Purposeful Questioning: Guiding Student Thinking

Christina Tondevold, founder of Build Math Minds, spent 10 years teaching middle school math before realizing that the traditional, algorithm first approach she'd learned and was teaching wasn't working for many of her students. She now calls herself a Recovering Traditionalist, and has spent the years since training K through 8 educators nationwide on building real number sense and conceptual understanding rather than step-by-step procedures.

Christina believes learning happens when students are given room to think, and even to struggle, rather than being handed a script to follow, a philosophy she'll bring directly to this session on purposeful questioning and guiding student thinking.
