Episode 203 - Number Sense with Christina Tondevold and Mona Iehl

In this cross-posted episode from Math Chat, host Mona Iehl interviews Christina Tondevold about developing number sense in elementary students. Christina shares her journey from a "procedural" math student to becoming a math coach and founder of Build Math Minds. The conversation explores the eight components of number sense: four early numeracy concepts (subitizing, verbal counting, object counting, and cardinality) and four number relationships (spatial relationships, one/two more or less, benchmarks of 5 and 10, and part-part-whole). Christina explains how these concepts help move students beyond counting to more efficient math strategies. Practical classroom strategies discussed include using sticky notes to assess students' visual number understanding, implementing subitizing activities, and strategically choosing numbers in word problems to reinforce key number relationships. Both educators emphasize the importance of allowing students to solve problems in ways that make sense to them, rather than forcing procedural approaches. This episode provides valuable insights for teachers looking to build true mathematical understanding rather than just procedural knowledge in their students.

The Build Math Minds podcast is for my fellow Recovering Traditionalists out there. If you don’t know whether or not you are a Recovering Traditionalist, here’s how I define us. We are math educators who used to teach math the traditional way. Flip lesson by lesson in the textbook, directly teaching step-by-step how to solve math problems. But now, we are working to change that to a style of teaching math that is fun and meets our students where they are at, not just teaching what comes next in the textbook. We want to encourage our students to be thinkers, problem solvers, and lovers of mathematics..we are wanting to build our students math minds and not just create calculators. If that is you, then this podcast is for you.
