Parabola Lab

Learning fit

Labels show who asserted each claim.

An Algebra 1 quadratics lab for ages 12-15: y = ax^2 + bx + c on a grid with a/b/c sliders, live vertex, y-intercept, and x-intercepts (quadratic formula, roots to 1 decimal), plain-language effect cards, and an a = 0 note ('a line, not a parabola'). The discriminant card shows b^2 - 4ac and predicts 2 crossings, 1 tangent, or 0 crossings. Target Practice sets 4 basket challenges tuned with a and c only, with the winning values displayed.
