Solve It! Pre-Algebra

Solve It! teaches pre-algebra, the math that comes before Algebra 1, one idea at a time, with animated pictures that show why each rule works: why two negatives make a positive, why you flip and multiply, why the same move keeps a balance level. When a skill clicks, the Play tab turns it into a quick game.

LEARN • Eight tracks and 36 short lessons on three paths. Numbers: Negative numbers, Fractions and decimals, Exponents and roots, Scientific notation. Proportion: Ratios and rates, Percent. Algebra: Expressions, Equations • Pictures for every idea: a thermometer, zero pairs, hops on a number line, x-bags, algebra tiles, an area model, a balance that makes the same move on both sides, ratio tables, double number lines, tape diagrams, percent bars, fraction bars, decimal grids, long division, square and cube stacks • Every lesson goes learn, practice, quiz, with no timer or lives • A wrong answer brings the picture back with a hint about that exact slip: adding the bottoms, flipping the wrong fraction, getting the sign wrong, reading a percent as dollars • Tell it where you are and it suggests a first lesson. Nothing is locked behind progress

PLAY • Five games: Integer blitz, Solve for x, Ratio tables, Percent of, Powers and roots • Pick the operations for Integer blitz, and one-step, two-step or negative equations for Solve for x • Beat the clock for 1, 2 or 3 minutes with 3 lives, or get 20, 40 or 60 in a row on a stopwatch • Four answer choices, a ready-set-go countdown, and a cheer at streaks of 5, 10 and 20 • Best scores and times for every game and challenge, lesson progress and recent games on the Results tab

PLAYERS • Optional local players, each with a name and an animal avatar • Each player's progress stays on this device
