Money Mat

About this tool

Money Mat is coin counting with the coins your children actually see. A warm market stall shows an illustrated item with a price tag; children tap coins from the purse onto the mat, and the running total counts up with soft clinks — a speaker chip says the total out loud whenever you want it. The coins are the real thing pedagogically: true relative sizes, real metal color families, and your locale's real denominations — euros and cents, Swedish kronor, Danish and Norwegian kroner, Brazilian reais, or dollars with a pounds toggle — with prices formatted the way your country writes them.

Paying exactly earns a warm thank-you and a gentle, dismissible invitation: can you make the same amount another way? A second, genuinely different combination is celebrated by showing both ways side by side with an equals sign — equivalence made visible, never graded. Every coin on the mat can be tapped back into the purse, and a not-yet-right total is simply silent: there are no buzzers, no red marks, and the stall keeper's smile never changes.

The small-price stall with every coin and the make-it-another-way invitation is free forever. Premium adds banknotes, bigger price bands, saved stalls for your center rotations, and the change-making mode: pick something to pay with — every choice offered is valid — and the stall keeper counts your change back coin by coin, out loud, the classic counting-on strategy made audible.

How to use it in class

• Project the stall and read the price tag together — small prices stay under one euro, dollar, pound, or ten kronor.
• Let a child tap coins from the purse onto the mat; watch the running total climb, and tap any mat coin to put it back.
• Tap the speaker chip to hear the total spoken in real money words whenever the class wants a check.
• After an exact payment, take the invitation: clear the mat and build the same amount a different way, then compare both ways side by side.
• In Premium, switch to Get change: the money paid stays beside the price, the purse offers only the coins that still fit, and each tap the child makes draws its own hop on the line, which the keeper says aloud — the change is named at the end.

Classroom ideas

• Coin hunt warm-up: show a price, and pairs race gently to find ONE way to pay it — then the class collects all the different ways on the board.
• Fewest-coins talk: after two ways are on screen, ask which way uses fewer coins and why — the equivalence discussion runs itself.
• Currency corner: with the pounds toggle (or a neighbour country's stall on another tablet), compare what the same small price looks like in two currencies.
• Change-back echo: in change mode, the class repeats each counting-on step aloud after the keeper — counting on becomes a chant.
• Saved-stall centers: save a stall per group with prices tuned to each group's band, and rotate groups through the same market.
