Identifying Problems
Students learn to ask questions and observe situations to identify problems that need engineering solutions.
Key Questions
- Analyze a situation to identify a specific problem.
- Differentiate between a problem and a symptom of a problem.
- Explain how asking questions helps to define a problem clearly.
Common Core State Standards
About This Topic
Goods and Services introduces the basic building blocks of the economy. Students learn to distinguish between 'goods' (physical items you can touch, like a toy or an apple) and 'services' (actions people do for others, like a bus driver or a doctor). This distinction is the first step in understanding how people trade and work to meet their needs.
This topic aligns with 1st grade economics standards. It helps students recognize the economic activity happening all around them. This topic is most successful when students can engage in a 'marketplace' simulation, where they can practice identifying and 'purchasing' both goods and services in a hands-on environment.
Active Learning Ideas
Stations Rotation: The Goods and Services Market
Set up stations with pictures or props (a toy car, a hairbrush, a 'doctor's' stethoscope). Students rotate through and must decide if each station is offering a good or a service, recording their answers on a simple chart.
Role Play: Helpful Neighbors
Students act out different jobs. One student might 'sell' a drawing (a good), while another 'washes a desk' (a service). The class identifies which is which and discusses why we need both in a community.
Think-Pair-Share: My Favorite Good and Service
Students think of one good they love (like a favorite snack) and one service they use (like getting a haircut). They share with a partner and explain why each one is important to them.
Watch Out for These Misconceptions
Common MisconceptionServices are always free.
What to Teach Instead
Explain that people get paid for their work (services) just like they get paid for making things (goods). Active 'play money' transactions for services like a 'car wash' can help reinforce that services have value and a cost.
Common MisconceptionIf I can't take it home, it's not a good.
What to Teach Instead
Focus on the 'touchable' aspect. An apple is a good even if you eat it right away. Using a 'Touch vs. Action' sorting game helps students clarify that goods are objects and services are actions.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
rubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
