Lesson Plan

Math in Nature Lesson Plan: Bigs Edition

Derive the golden ratio, test bold claims about it, and measure hexagons and fractals.

This is the Bigs Edition of Math in Nature: one ready-to-teach week written just for grades 7-8. Every day follows the same rhythm: Reading on Monday, Writing and Words on Tuesday, Science and Math on Wednesday, a Hands-on Project on Thursday, and Show and Tell on Friday.

The big question: Is the golden ratio really nature's secret code, or do people see it where they want to?

The Week

• Mon: Euclid's Mean Ratio (Reading) • Tue: Myth or Math? (Writing & Words) • Wed: Ratio Convergence Lab (Science & Math) • Thu: Honeycomb Hexagons (Hands-on Project) • Fri: Fractals and Final Talk (Show & Tell)

Teaching more than one level? The all-levels edition of Math in Nature has Littles (K-3), Middles (4-6) and Bigs (7-8) in one file, so siblings or a mixed classroom can study the same topic together.

Perfect for homeschool families, grade 7-8 classrooms, co-ops and substitute plans.
