Math Squares

About

It plays like classic concentration, except instead of flipping two identical cards you're pairing a number with its square — 7 with 49, 12 with 144 — so speed only helps once the math is solid. Small numbers you'll just know, but the bigger ones push you to factor on the fly before your next flip. It's a quick way to get faster at squares without it feeling like homework.

Controls

Click or tap a card to flip it, then flip a second card to try to match a number with its square.

Tips

• For bigger numbers, break them into factors you already know instead of trying to recall the square outright.
• Track cards you've already seen flipped — memory matters as much as math once the grid fills up.
