- Estimation 180 – Day 179 (Andrew Stadel)
- Warm Up / Exploration (New Visions)
- Go over Concept Quiz
- Students complete analysis handout in order to prepare for retake. See retake policy and learning folders post for more details.
- Common Core
HSA.REI.B.4.B – Solve quadratic equations by inspection (e.g., for x² = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
- A.8(A) – solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formula
