Money match
Tape two pennies onto two index cards, then do the same with nickels, dimes, and quarters. Turn the cards over, mix 'em up, and have your child match pairs by flipping two at a time. Ditch one set of cards, write each coin's name on new cards, flip 'em over, and have her match coins to their names this time.
Pricey puzzles
Download photos of a $5, a $10, and a $20 bill from moneyfactory.gov/section.cfm/4 (or just do a Google image search for "dollar bill"; if the photos say "sample" or "specimen" in bold type on them, they're legal to print out). Cut them up into several large pieces. Scramble them, then have your child reassemble each bill. Let him peek at real bills for help.
Coin riddles
Make some up -- for instance, "I'm orangey-brown, have Abraham Lincoln on my front, and I'm worth one cent. What am I?"
Guess who?
Fold a bill so just one part of it is showing -- say, George Washington's white hair on the $1 bill -- then gradually reveal more bits until your child guesses how much you're holding.
