High School: Videos

These videos, drawn from Chapter 3 Number Sense of the California Mathematics Framework, highlight effective strategies for developing number sense in young learners. Each clip features classroom-based examples that illustrate how foundational math concepts can be explored through play, conversation, and problem-solving. 

Together, they support educators in bringing the Framework’s vision to life by modeling instructional approaches that build confidence, curiosity, and a deep understanding of numbers in high school classrooms.
