This game was a hit in my classroom. Print out the 25 cards and shuffle them up. Divide your class into groups and have them compete as they try to put the fractions in order from least to greatest . To increase difficulty, ask them to also write the decimal equivalent, and you will find misunderstandings as they begin to explore the relationship between tenths and hundredths. It's a great way to check for understanding and teach valuable fractions skills before the big test.
This could also work well as a math center.
