The Common Core State Standards include functions starting in 8th grade, and throughout high school. I support that emphasis.

Over the years, I have developed chunks of curriculum at all those levels. See if any of the links below take you to something you can adopt or adapt for your classes.

### 8th Grade

### Basic Algebra

*Algebra: Themes, Tools, Concepts* contains many lessons on functions.

Use this index to find dozens of lessons on:

- Direct and inverse variation
- Exponential functions
- Linear functions
- Quadratic functions
- Slope and rate of change
