I've created 4 sets of cards with 12 cards in each set, allowing you to rotate them throughout the school year. The front of the cards has different assortments of pennies, nickels, dimes and quarters, and 3 possible answer choices. Answers are marked on the back of the cards for control of error and independent practice. All sets have answers shown in two ways (written as cents, and also as decimals with a dollar sign) so that your students have practice seeing them written both ways.Enjoy!
