Number Pyramid is a math puzzle for kids — and anyone who likes numbers. Some boxes in the pyramid show a number; the rest are blank. Each box is made from the two boxes beneath it — their sum in the early grades, their product later on. Use what you know to work out the rest. A preset for each grade from Kindergarten to Grade 6 follows the school curriculum: numbers to 10 in Kindergarten, adding and subtracting up to 10,000 by Grade 4, then multiplication in Grade 5 and division in Grade 6. Kids play at their own pace. Hints walk them through any box they're stuck on, one step at a time, and a scratchpad is there for working the math by hand. Free: Kindergarten, Grade 1 and Grade 2, with hints, scratchpad, and progress tracking. One purchase unlocks everything else, for the whole family: Grades 3 to 6, up to six player profiles, Time Challenge — a race against the clock with rising levels, in add/subtract or multiply/divide mode — and custom difficulty (pyramid height, number size, operators, negative numbers). No data collected. No ads, no tracking. Works offline.
