Tape or glue coins to index cards, creating a pair of cards for each coin. One card should display the front, while the other displays the back. Use these as flash cards or as cards in a matching game, allowing children to match the front of the coin with the back of the coin. Include coins that have unusual designs, such as state quarters and wheat pennies, if you can find them.
Tape or glue coins to index cards to create a memory matching game. Place all the cards face-down and allow children to turn over a pair. If the coins on the cards match, you can challenge the child to name the coin or state the value of the coin. If the cards don't match, the two cards are turned over again and the next child takes a turn flipping cards.
Print out coin bingo sheets on sturdy card stock from a website like Math Worksheet Wizard. You can select how large the bingo grid is for each sheet, then click the "Make Worksheet" button to receive a new, randomly generated bingo sheet each time. Place coins into a bag or bowl and select a child to play the announcer. The child draws a random coin from the bowl and announces it to the class. Each child places a bingo chip on the corresponding coin on his sheet until someone gets a bingo.
Place various items on the "store" counter, each with a price tag. Supply children with either real or fake coins, which they can use to "purchase" the items from the store. You can also assign random students to be the cashier, who must take the money and check it for accuracy. This helps children learn the value of each coin and basic money math.
