Design a Dream Theme Park: Math in the Real World

Materials Needed

• Paper or graph paper
• Pencils, colored pencils, or crayons
• Ruler
• Scissors and glue, optional
• Calculator, optional
• Coins or play money, optional
• Planning sheet or notebook

Lesson Overview

Suggested age: Grade 4

Time: 60–75 minutes, with the option to divide the lesson into two sessions

Big idea: Math helps us plan, measure, design, and make decisions in the real world.

Learning Objectives

By the end of the lesson, the learner will be able to:

• Use multiplication or repeated addition to calculate the area of rectangles.
• Use a simple budget to add costs and find the amount remaining.
• Represent a design on a map using labels, measurements, and a key.
• Explain at least two decisions made while creating a theme park.

Success Criteria

A successful theme park plan will include:

• At least four labeled attractions or areas.
• Correctly calculated areas for at least three rectangular spaces.
• A total budget of $1,000 or less.
• A map key and clear labels.
• A short explanation of the choices made.

Introduction: The Challenge

Imagine that you have been hired to design a brand-new theme park. You have a piece of land, a limited budget, and many exciting ideas. Your job is to create a park that is fun, organized, and affordable.

Hook question: If you could build one attraction in your dream theme park, what would it be? What would people do there?

Tell the learner: “Today you will use math like a real designer. You will measure spaces, plan a map, manage money, and explain your decisions.”

Part 1: I Do — Modeling the Math

Mini-Lesson: Finding Area

Explain that area tells how much space a flat surface covers. For a rectangle:

Area = length × width

Model an example:

A snack shop is 6 units long and 4 units wide.

6 × 4 = 24 square units

Explain that “square units” might mean square feet, square meters, or simply squares on graph paper.

Mini-Lesson: Managing a Budget

Model a simple budget:

Add the costs: $350 + $150 + $200 = $700.

Subtract from the total budget: $1,000 − $700 = $300 remaining.

Quick check: Ask, “Could we spend another $250? How do you know?”

Part 2: We Do — Plan Together

Step 1: Choose the Park’s Theme

Invite the learner to choose one theme:

• Space adventure
• Jungle exploration
• Underwater world
• Fairy-tale kingdom
• Invent a different theme

Step 2: Create a Shared Budget

Use the following sample costs, or invent reasonable costs together:

The learner chooses features while keeping the total at or below $1,000. Use coins, play money, or written calculations to make the budgeting hands-on.

Think-pair-share variation: The learner first decides independently, explains the choices aloud to a parent or partner, and then revises the plan if needed.

Step 3: Practice Area Together

Choose three park features and calculate their areas together.

Formative check: Ask the learner to explain why the area is measured in square units and not just units.

Part 3: You Do — Create the Theme Park

Instructions

1. Give the park a creative name.
2. Choose a theme.
3. Select attractions and features without spending more than $1,000.
4. Draw the park on paper or graph paper.
5. Use rectangles or other simple shapes for the park areas.
6. Label each feature.
7. Write the length, width, and area of at least three rectangular spaces.
8. Add paths, entrances, signs, trees, benches, or other details.
9. Create a map key, such as a star for rides or a fork-and-knife symbol for food.
10. Write three to five sentences explaining the design.

Design Choices

The learner may choose how to present the final project:

• A colorful paper map
• A three-dimensional model using recycled materials
• A digital drawing or slide presentation
• An oral presentation using the completed planning sheet

Real-World Connection

Theme park designers, architects, engineers, and business owners use the same skills when planning real spaces. They calculate how much room is available, decide how to spend money, make maps, and consider how people will move safely through an area.

Assessment

Formative Assessment During the Lesson

• Ask the learner to explain the area formula in their own words.
• Check one budget calculation before the design begins.
• Ask, “What will happen if this attraction is too large for the available space?”
• Have the learner estimate an area before calculating it.
• Ask the learner to explain one design choice and one budget choice.

Summative Assessment: Theme Park Presentation

The learner presents the map or model and explains:

• The park’s theme and name
• The attractions included
• Three area calculations
• The total amount spent and money remaining
• Two reasons for the design choices

Simple Rubric

Differentiation and Support

For Learners Who Need More Support

• Use graph paper so each square represents one unit.
• Provide an area formula card: “Area = length × width.”
• Limit the design to three features.
• Use whole-number dimensions and a prepared price list.
• Work with play money or drawings before writing equations.
• Allow the learner to explain answers orally instead of writing a paragraph.

For Learners Ready for an Extension

• Calculate the total area of the entire park.
• Include a nonrectangular feature and estimate its area.
• Create ticket prices and calculate possible earnings from 20 visitors.
• Add a second budget and compare which plan provides better value.
• Use a scale, such as 1 graph-paper square = 2 meters.
• Design an accessible route that connects every major attraction.

Conclusion: Recap and Reflection

Invite the learner to complete these statements:

• “Area tells us...”
• “To find the area of a rectangle, I...”
• “A budget helps us...”
• “One design choice I made was... because...”
• “If I redesigned my park, I would...”

Recap the main learning: “Today you used multiplication to measure space, addition and subtraction to manage a budget, and creativity to solve a real-world design problem.”

Optional Follow-Up Activity

Write a short advertisement for the theme park. Include the park’s name, its most exciting attraction, the ticket price, and one reason visitors should come.
