In this lesson, you learned how to:
- Describe how a pattern is growing.
- Tell whether a pattern is growing linearly, exponentially, or quadratically.
- Explain that an expression with a squared term is called quadratic.
Here are the activities that helped you reach those goals:
- 7.2.1: Squares in a Geometric Pattern
- In this activity, you explored how different expressions can represent the same figure and still be equivalent.
- 7.2.2: Constant and Exponential Change
- In this activity, you wrote an expression to describe a pattern, and then you graphed the values of the step and the number of dots in each figure. One was linear, while the other was not.
- 7.2.2: Self Check
- 7.2.2: Additional Resources
- 7.2.3: Quadratic Expressions
- In this activity, you explored a quadratic relationship, including what makes it quadratic and not linear or exponential.
- 7.2.3: Self Check
- 7.2.3: Additional Resources
- 7.2.4: Quadratic Relationships
- In this activity, you examined three patterns and chose which one represents a quadratic relationship.
After these activities, you completed the following practice:
- 7.2.5: Practice
