Frequently asked questions
Is proof writing supported?
Yes. Units build proof skills gradually, from simple angle relationships to full two-column proofs, with models and practice.
What grade levels are these for?
They are written for Grades 9–12 and work across on-level and honors geometry classes. Differentiated and optional tasks let you scale the difficulty up or down for mixed-ability groups without extra prep.
What files do I get, and can I reuse them?
Each resource downloads instantly as editable Microsoft Word worksheets and answer keys plus a PowerPoint slide deck, so you can print class sets or teach digitally. A purchase is licensed for your own classroom, so you can reuse it with new students every year.
