Most "precalculus" classes include a wide range of topics, only some of which are actually preparation for calculus. That is as it should be. Yes, being ready for calculus is important: it helps keep education and career options open. But a well-rounded math education can and should include other subjects. On this page, I link to materials that belong in high school math courses beyond Algebra 2.

## Basics

- If your students' grasp of Algebra 2 topics is tenuous, you may need to find interesting ways to review those ideas. Check out the materials on Seeking Depth in Algebra 2. In particular:
- Quadratics: Geometry-Graphing Connection | Completing the Square
- Sequences and Series
- Functions: Exponentials | Logarithms | Inverse Variation | Square Root | Sine
- See also: Rate of Change

## Going Deeper

- Deeper and further:
- Quadratics: Three Paths to the Quadratic Formula | a graphical path | another graphical path
- Geometry of the Parabola: 2D | 3D | Similarity
- Complex Numbers
- Rate of Change: Doctor Dimension

## And More!

- Expand your students' mathematical horizons!
- The Conic Sections
- Function Diagrams
- Iterating Functions
- Transformational Geometry
- Symmetry, Transformations, Dimensions: Space
- Infinite Sets, Dynamical Systems, Mathematical Induction, Fractals: Infinity
