Unit Plan 28 (Grade 3 Social Studies): Needs, Wants, and Scarcity

Focus: Understand needs vs. wants and how scarcity (limited resources) means making choices, using simple classroom simulations and basic information sources (charts, lists, photos) to decide how to use resources.

Grade Level: 3

Subject Area: Social Studies (Economics • Inquiry/Skills)

Total Unit Duration: 5 sessions (one week), 45–60 minutes per session

I. Introduction

In this unit, students explore the difference between needs and wants and how scarcity means we cannot have everything we might like. Through simple simulations (limited supplies, class store, planning a celebration), they experience how people must choose and think about what is most important. Students also learn to use basic information sources (lists, charts, “ads,” photos) to help them make thoughtful decisions instead of guessing. By the end of the week, each student will create a short “Smart Choices” reflection or mini-poster explaining a choice they made in a simulation, what they gave up, and why.

Essential Questions

• What is the difference between needs and wants?
• What is scarcity, and how does it force people to make choices?
• How do our choices show what we think is most important?
• How can information (lists, charts, pictures, simple “ads”) help us make better choices when resources are limited?
• Why is it important to think about both ourselves and others when we decide how to use limited resources?

II. Objectives and Standards

Learning Objectives — Students will be able to:

1. Define and give examples of needs (things we must have to live and be safe) and wants (things that are nice to have but not necessary).
2. Describe scarcity as having limited resources and explain that we must make choices when we cannot have everything.
3. Participate in simple classroom simulations (limited supplies, class store, celebration planning) and explain at least one choice they made and what they gave up.
4. Use basic information sources (lists, charts, photos, or simple “ads”) to compare options and decide how to use limited “class bucks” or supplies.
5. Create a short “Smart Choices” reflection or mini-poster that explains a decision they made, how scarcity affected it, and why their choice made sense.

Standards Alignment — 3rd Grade (C3-based custom)

• 3.C3.Econ.1 — Explain needs vs. wants and how scarcity requires choices.
  • Example: Decide how to spend limited “class bucks” for a celebration.
• 3.C3.Inq.2 — Gather information from multiple sources (maps, charts, photos, primary/secondary texts, interviews).
  • Example: Use a town map, a park brochure, and a short news article to learn about a new trail.

Success Criteria — Student Language

• I can tell the difference between a need and a want and give examples of each.
• I can explain that scarcity means we have limited resources and must choose.
• I can describe a choice I made in a simulation and what I gave up.
• I can look at simple charts, lists, and pictures to help me decide how to use my “class bucks” or supplies.
• I can write or draw a Smart Choices explanation that shows I understand needs, wants, and scarcity.
