High School: Lessons

These lessons, inspired by Chapter 3 of the California Mathematics Framework, highlight effective strategies for building number sense in young learners. Each lesson offers developmentally appropriate experiences that connect math to real-life contexts through play, hands-on exploration, and meaningful discussion.

Together, they support educators in bringing the Framework’s vision to life by modeling instructional approaches that nurture curiosity, confidence, and a strong foundation in mathematics for high school students.
