A free SAT advanced-math game where you write the equation
Curve Rider drills SAT Advanced Math: writing equations for nonlinear functions and finding the key features of a parabola. The park hands you a contract for a coaster hill, where the crest sits, where it touches the ground, how high it leaves the platform. It never gives you the equation. You write it, and the park builds exactly what you typed.
How to play
Read the contract, then type a track equation in the box. A keypad gives you x, the ^ symbol for powers, and parentheses. Any algebraically equivalent form works: vertex form and standard form describe the same hill, so both ride. Hit Draft to check every marker on paper, then Build it. The crew then asks one thing about the curve you wrote, the touchdown or the crest height, and they build to your answer.
Common questions
Is Curve Rider free?
Yes. It runs in your browser with no login and no signup. The Forge diagnostic that shows where your points are going is free too.
Which SAT skill does Curve Rider train?
SAT Advanced Math. You practice writing equations for nonlinear functions, working with quadratics in vertex and factored form, and finding key features like the vertex and the zeros of a parabola.
Do I have to write the equation in one exact form?
No. The park checks the track by its shape, not its spelling, so vertex form, factored form, and standard form all pass as long as the curve hits every marker the contract asks for. Curve Rider stays with parabolas, so keep it to x and x².
