DEPS: Multiply & Divide

DEPS turns multiplication and division into a world of small adventures — and teaches the strategies behind the answers, not just the answers. Seven worlds, seven ways of thinking: • Doubling Farm — multiply by doubling • Break-Apart Factory — split numbers into tens and ones • Wizard's Tower — round to an easy number, then compensate • Array Garden — multiply with the area model • Pirate Treasure — divide by sharing place by place, trading as you go • Jumbo the Elephant — divide by subtracting chunks • Estimation Arena — decide if an answer is reasonable WHAT MAKES DEPS DIFFERENT • Strategies, not tricks. Every world teaches one way of thinking, drawn from a standard teacher-education text on how children actually learn arithmetic. • It catches misconceptions. When a child makes a classic mistake — adding the carry too early, forgetting the cross parts, skipping a zero in the middle — DEPS recognises it and sends a targeted practice mission. • Boss stages with a twist. Instead of answering faster, the child hunts for the error in a friend's work. • Written notation the way your country writes it. Symbols and the long-division layout follow local school convention, in 8 languages. FOR PARENTS AND TEACHERS • A follow code shows progress on another device: stars, accuracy per world, and the misconceptions worth working on. A teacher can follow a whole class. • A detailed report can be emailed with one tap. • A daily level limit keeps sessions short, and a parent PIN guards the settings. • No ads, no tracking, no third-party analytics, no account required.
