Semester review: the connected story

Connect functions, quadratics, and polynomials as one story by analyzing a single real-world model with multiple tools.

This semester built one connected story more than a stack of separate topics: functions gave us a language (domain, range, notation, transformations); quadratics gave us the first curved functions worth mastering deeply (vertex form, factoring, completing the square, the formula, complex numbers); polynomials generalized that curve family further (end behavior, factoring, division, roots). One well-chosen real scenario can touch all three chapters at once.

Review by connection, not repetition: when a problem feels unfamiliar, ask "which chapter of the story is this asking about?" -- then reach for that chapter's specific tool. The best sign you have really learned the semester is jumping between tools on the SAME scenario, not just executing one recipe in isolation.

📋 For the teacher
Teach it (10–15 min):
  • Have them build a one-page concept map of the semester: functions, quadratics, polynomials as three big nodes, with arrows showing how each connects to the next.
  • Run the ball scenario as a conversation, not a worksheet: for each question, ask "which tool, and why that one?" before any computing starts.
  • Revisit their two or three weakest weeks (they usually know which ones) with a handful of problems each -- targeted review beats redoing everything.
  • Point out explicitly how a physical constraint (like t >= 0) restricts a function's domain, even when the algebra itself would allow more values.
Talk about it:
  • How are quadratic functions a special case of the more general polynomial functions from recent weeks?
  • Why does the physical situation (a ball in the air) restrict the domain of h(t), even though the equation itself is defined for all real t?
  • Which single idea from this semester showed up the most across different weeks?

Mastery looks like: Given one real scenario, they can apply function, quadratic, and polynomial tools appropriately and explain why each tool applies.

Common stumbles: Treating the semester's topics as disconnected recipes instead of recognizing when several tools apply to the same problem; ignoring a real-world domain restriction that the pure algebra would not flag.
