Study guide: Buying, Making and Reusing
Trace making, buying, saving and using materials.
Ideas to explain in your own words
- A buyer obtains a good or service. A seller offers it in exchange for payment. A price states how much is asked for one item or service. Payment completes the stated exchange; a price label alone does not prove an item was purchased.
- Production changes inputs into a product. A raw material has not yet been turned into the stated finished item. A tool helps with the work; labor is the work people perform. Scrap is leftover material. Not every leftover is waste; some can be reused.
- Money can be spent now, saved for later or given to help someone else. Borrowing means receiving something with an obligation to return it under an agreement. These fictional examples teach choices; they do not ask learners to disclose money or make a real purchase.
- Resources are limited. Reusing an object means using it again; repairing means fixing it. Recycling processes material into new material or products. Reducing means using less in the first place. These actions can overlap, but match the action directly stated in each fictional card.

Watch your reasoning
- Mixing up Buyer and Seller. Re-read what each note says before choosing.
- Adding a detail that is not on the card. Point to the words that help explain your answer.
A worked review example
Worked example: The card says: “A fictional customer purchases a loaf.” That matches Buyer. Buyer is the person obtaining the item or service. Compare the note for Price: Price is the stated amount charged for an item or service. That is a different clue.
Make a practice plan
- Read or listen to the notes in the four lessons. An adult can read aloud.
- Try each lesson’s main question and three practice questions. Say, draw or write what helped you choose.
- Use the review cards, then try the changed card in any lesson you want to practice again.
- Complete the four-box task. Then try the separate subject-test cards.
