- Answer Key
- Join to access all included materials
You are used to teaching repeating decimals with bar notation that keeps us from writing that number over and over again; now teach what the over and over again represents. This activity allows your mathematicians to explore the infinite decimal and see how different calculations get us close to the original number, but not quite exactly on it. The lesson plan includes commentary and a solution key to help guide the activity.
- Useful commentary
- Promotes open thinking about repeating decimals
- Can be used with or without a calculator
