Units
Start with the Unit worksheet to review the main ideas. For extra support or practice, choose a level below. PDFs open in a new tab; print or save them from your browser. Use the paired answer guide to check your work.
- Concept: start with the core idea.
- Practice: build fluency with more questions.
- Advanced: try more challenging problems.
Students revisit functions through sequences, seeing arithmetic and geometric sequences as linear and exponential functions restricted to integer domains, and represent and model situations using sequences.
