In this lesson, you will work with problems that show patterns of change and be able to describe the patterns in mathematical terms. A new term, quadratic, will be used to describe patterns with squared terms.

When you finish this lesson, you will be able 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 will help you reach those goals:

• 7.2.1: Squares in a Geometric Pattern
• 7.2.2: Constant and Exponential Change
  • 7.2.2: Self Check
  • 7.2.2: Additional Resources
• 7.2.3: Quadratic Expressions
  • 7.2.3: Self Check
  • 7.2.3: Additional Resources
• 7.2.4: Quadratic Relationships

After that, you’ll practice and review.

• 7.2.5: Practice
• 7.2.6: Lesson Summary
