In this lesson, you will experiment with expressions and equations to model a situation: planning a pizza party. For instance, what are the relevant quantities when planning for a pizza party? Are these quantities fixed or do they vary? How they might relate to one another? Are there any limitations or constraints on how much pizza should be ordered?
When you finish this lesson, you will be able to:
- Tell which quantities in a situation can vary and which ones cannot.
- Explain the meaning of the term “constraint.”
- Use letters and numbers to write expressions representing the quantities in a situation.
Here are the activities that will help you reach those goals:
- 1.1.1: Understanding Value
- 1.1.2: Creating Expressions to Estimate Cost, Part 1
- 1.1.2: Self Check
- 1.1.2: Additional Resources
- 1.1.3: Understanding Constraints
- 1.1.3: Self Check
- 1.1.3: Additional Resources
- 1.1.4: Creating Expressions to Estimate Cost, Part 2
After that, you’ll practice and review.
- 1.1.5: Practice
- 1.1.6: Lesson Summary
