AP Precalculus Why a Slant Asymptote? After dividing, f(x) is a line plus a remainder. Plug in x = 10, 100, 1,000 and up, and watch the circled remainder part get closer and closer to 0. Seven examples. Open tool (opens in a new tab)
All courses Word Anatomy Take a math word apart: split it into colored parts, learn what each part means, predict the meaning with a partner, then check the definition and find other words with the same parts. Ten words built in, or type any word and it breaks it down for you. Open tool (opens in a new tab)
AP Precalculus Area Model Division Divide a polynomial by filling the area model backward, one box at a time, next to the same problem in numbers (x = 10). Seven examples, with and without remainders. Open tool (opens in a new tab)
Algebra 1 Coordinate Plane Explorer Click the graph to place a point. Dashed lines run back to each axis, so students see exactly where the x and the y come from. Open tool (opens in a new tab)
AP Precalculus Unit Circle Retrieval A timed walk around the unit circle. Students name each angle, then each point, with think time before every answer. Open tool (opens in a new tab)
AP Precalculus Leading Term Takes Over Slide x away from 0 and watch a polynomial zoom out until it looks just like its leading term. End behavior, made visible. Open tool (opens in a new tab)
