7th Grade


The Seventh Grade mathematics program helps students develop the habits and skills necessary to practice math like real-world mathematicians.

Seventh Graders start to practice mathematics, not as a set of facts and algorithms to be memorized or imitated, but as a creative exploration and reflection of our mind’s interaction with the world.  Throughout the course, students make meaning (i.e. discover the logic) of the concepts and refine their understanding by expressing it in precise language, diagrams, and symbols that convince and teach others. Work routines are designed to develop a balance of number sense and calculational fluency, depth of understanding, consideration of multiple strategies and representations, growing self-advocacy and responsibility for one’s own learning, and increasingly higher-quality solutions. The primary curriculum for middle school math is Open Up Resources – Illustrative Mathematics, which is supplemented by rich problems, extensions, and practical assignments.
