Sample High School Math lesson plan
A real plan Classly AI generated — copy it, remix it, or use it as a benchmark.
Students will analyze and graph a quadratic function and interpret its key features in context.
Project a graph with no labels; students write three observations and one question using academic vocabulary (vertex, intercept, axis of symmetry).
- Visual: Desmos investigation — adjust a, b, c sliders and journal the effect on the graph's shape.
- Auditory: small-group 'teach the parabola' — each group explains one key feature to the class in 90 seconds.
- Kinesthetic: human parabola — students hold cards with x-values and step forward by the y-value to form the curve.
- Reading/Writing: write a real-world scenario (projectile, profit, arch) that a given quadratic could model.
- Find a real parabola in your neighborhood (bridge, fountain, arch). Photograph it, sketch a coordinate plane over it, and estimate the vertex.
- Voice-memo defense: explain in 90 seconds why y = -x² + 6x − 5 has a maximum and where it is.
Why this works: AI-resistant assignments anchor the task in a place, person, or process ChatGPT can't reach.
For y = x² − 4x + 3, name the vertex, axis of symmetry, and roots. One sentence on what each tells you.
FAQ
With Classly AI, about 30 seconds. Paste the standard or topic, choose 15 / 60 / 90 minutes, and the plan generates with warm-up, instruction, practice, and check-for-understanding sections — all calibrated for high school students.
Yes. You can paste in your state standard (Common Core, TEKS, NGSS, B.E.S.T., etc.) and Classly AI will scaffold the plan to that learning objective, with a self-critique pass against Bloom's Taxonomy and UDL.
Every math plan includes an AI-resistant homework section: oral defenses, in-class artifacts, primary-source work, or local fieldwork — assignments LLMs literally can't outsource.
