Lesson Plan (Grades 3-5): Build a Theme Park - Area, Perimeter, Budgeting, and Big Design Decisions

Focus: Turn area, perimeter, and budgeting into an exciting theme park design challenge where students plan rides, walkways, food stands, and attractions on a grid. Students calculate area and perimeter, manage a pretend budget, make layout decisions, and justify how their design is fun, realistic, and mathematically accurate.

Grade Level: 3-5

Subject Area: Math • Financial Literacy • Design/Engineering Thinking • Speaking & Listening

Total Unit Duration: 1 core lesson with 2 optional extension lessons

I. Introduction

Students become theme park designers in a highly visual math project where every ride, path, and attraction must fit on a grid and stay within a pretend budget. In the core lesson, students design a small theme park map using square units, then calculate the area and perimeter of selected attractions. They must also make decisions about where to place rides, how much space each attraction needs, and how to spend limited funds wisely.

The lesson feels creative and engaging, but the math stays central. Students must show accurate measurements, explain design choices, compare costs, and defend why their park layout works. By the end, students understand that real-world design often requires both imagination and careful mathematical reasoning.

Essential Questions

• How can area and perimeter help us design a real or imaginary space?
• How do designers use grids, measurements, and budgets to make decisions?
• Why might two attractions with the same area have different perimeters?
• How can a limited budget affect what we build and where we place it?
• How can we explain and defend a design using math evidence?

II. Objectives and Standards

Learning Objectives — Students will be able to:

1. Design a simple theme park layout on a grid using square units.
2. Calculate the area of rectangular rides, attractions, or spaces by counting squares or multiplying side lengths.
3. Calculate the perimeter of selected attractions or park sections by adding side lengths.
4. Use a pretend budget to make choices about rides, paths, decorations, or food stands.
5. Compare different layout choices and explain how area, perimeter, and cost affect the design.
6. Present a final theme park plan using accurate math vocabulary and clear reasoning.
