Learning Goals
Students will be able to compare and justify factoring quadratic equations using GCF first, trinomial factoring, and factoring by grouping to determine the most efficient method.
Students will be able to solve quadratic equations and identify when factoring produces real solutions or no real factorization to explain the limits of the method.
Students will be able to analyze and defend why a quadratic polynomial has two roots by connecting factors, zeros, and the Fundamental Theorem of Algebra.

Quadratic Factoring Evidence Log and Written Claim
Each student submits an evidence log showing the same quadratic solved by GCF, trinomial factoring, and factoring by grouping, with short credibility-style notes about which method is most efficient and why. The write-up ends with a clear claim, warrants, and a fair counterexample or limitation.
Quadratic Methods Gallery Walk Defense Board and Oral Defense
Each team creates a gallery walk board that solves one quadratic three ways and defends a group claim about the best method for that case. The team presents, answers peer questions, and synthesizes where the strongest mathematical evidence supports their claim.
