Playground Design Challenge: Math in Motion

Grade 2Math5 days

In this project, second-grade students take on the role of playground designers tasked with redesigning their school's broken playground. Using their knowledge of addition, subtraction, and place value, students must choose equipment, calculate costs, and stay within a budget. The project culminates in a presentation of their playground design, showcasing their understanding of mathematical concepts and real-world problem-solving skills. Students will also reflect on their design choices and the challenges they faced during the project.

Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we design a playground that is fun, safe, and within budget, using our knowledge of addition, subtraction, and place value to calculate costs and materials?

Essential Questions

Supporting questions that break down major concepts.

How can we use addition and subtraction to plan our playground?
How does understanding place value help us calculate the cost and materials for the playground?
How can we represent our playground design and its costs effectively?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:

Apply addition and subtraction within 1000 to calculate playground costs.
Use place value understanding to determine the quantity of resources.
Design a playground plan, accounting for budget and resource constraints.

Common Core Standards

2.NBT.B.7

Primary

Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.Reason: Directly involves addition and subtraction within 1000, which aligns with the project's focus on calculating costs and materials.

Entry Events

Events that will be used to introduce the project to students

The Broken Playground

The current school playground is falling apart! The principal tasks your class with redesigning it. Students must assess the damage, propose new equipment, and calculate costs, all while adhering to a strict budget using their math skills.

📚

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.

Activity 1

Playground Inventory Ace

Students begin by assessing the current state of the 'broken' playground. They will count and categorize existing equipment, noting what needs replacement or repair. This activity introduces them to the real-world application of their math skills.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Visit the existing playground with a clipboard and worksheet.

2. Count and record the number of swings, slides, benches, etc.

3. Note any equipment that is broken or needs repair.

4. Categorize equipment by type (e.g., swinging, sliding, climbing).

Final Product

What students will submit as the final product of the activityA detailed inventory list of the current playground equipment, with notes on its condition.

Activity 3

Equipment Cost Calculator

Students research the cost of different playground equipment. They will use catalogs or online resources to find prices and calculate the total cost of their dream playground. This activity directly applies addition skills within 1000.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Provide students with a catalog or access to online resources featuring playground equipment and prices.

2. Students select equipment from their blueprint and find the corresponding prices.

3. Students use addition to calculate the total cost of their selected equipment.

4. Record the cost of each item and the total cost in a table.

Final Product

What students will submit as the final product of the activityA detailed cost breakdown of their dream playground, including individual item prices and the total cost.

Alignment

How this activity aligns with the learning objectives & standardsDirectly aligns with 2.NBT.B.7 by requiring students to add within 1000 to calculate the total cost of the playground equipment.

Activity 4

Budget Balancing Act

Students are given a budget for the playground project. They must revise their initial design to fit within the budget, making choices about which equipment to include or exclude based on cost. This activity reinforces both addition and subtraction skills.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Present students with a budget for the playground project (e.g., $800).

2. Compare the total cost of their dream playground with the given budget.

3. If the cost exceeds the budget, students must remove or substitute equipment to lower the total cost.

4. Recalculate the total cost after making changes, ensuring it fits within the budget.

Final Product

What students will submit as the final product of the activityA revised playground design and cost breakdown that fits within the given budget, showing which equipment was chosen and why.

Alignment

How this activity aligns with the learning objectives & standardsDirectly aligns with 2.NBT.B.7 by requiring students to add and subtract within 1000 to manage the playground budget effectively.

Activity 5

Presentation of Plans

Students present their final playground designs to the class, explaining their choices and how they stayed within budget. This activity enhances their communication skills and reinforces their understanding of the mathematical concepts involved.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Prepare a short presentation explaining their playground design and cost breakdown.

2. Explain why they chose specific equipment and how they managed to stay within budget.

3. Present their design to the class.

4. Answer questions from classmates and the teacher about their design and budget.

Final Product

What students will submit as the final product of the activityA presentation showcasing their playground design, cost breakdown, and justification for their choices.

Alignment

How this activity aligns with the learning objectives & standardsReinforces 2.NBT.B.7 by requiring students to explain their addition and subtraction strategies in a real-world context.
