This set includes 24 money cards with various amounts of coins. The students will add up the coins to find the value, and record their answers on their recording sheet. When they are done, they can use a QR reader program to check their answers on the key! (Or, the regular key if your classroom doesn't have access to the technology portion!)
I use these as stations, and the students rotate, however, they could be used for individual practice, or in any other way you see fit!
