Engage your students in real-world engineering with this 10-page, black-and-white “Disaster Zone: Circular Shelter Engineering” worksheet pack. Designed for strong Grade 6 differentiation, this Pi Day resource blends area of circles, circumference, surface area, percent reasoning, budgeting, and structural comparison into a high-interest disaster response narrative.

Students act as structural engineers designing circular hurricane shelters for a coastal emergency zone. On each worksheet, they analyze blueprints, calculate material costs, compare structural designs, evaluate budgets, and justify engineering decisions using mathematics.

Each worksheet contains 10 rigorous open-response questions with increasing complexity across the set. No multiple choice. No coloring tasks. Just structured problem solving, proportional reasoning, and applied geometry.

All calculations are accurate and consistent using π = 3.14 unless otherwise stated.

What’s Included:

Worksheet 1: Emergency Shelter Prototype
