Adding fractions with like denominators is a review subject from 4th grade, but there are elements that make this lesson decidedly a 5th grade topic.  I decided that the best way to get my students to multiple problems (happily), I needed to play a  game.  I decided to do a four-in-a-row type game, which was aided by the Bingo Card generator.  This allowed me to generate 30 cards using the same answer choices in no time at all! 

During this activity, students were exposed to:

• adding fractions with like denominators
• subtracting fractions with like denominators
• converting mixed numbers to improper fractions
• converting improper fractions to mixed numbers
• learning how to "borrow" from whole numbers to create mixed numbers
• simplifying fractions

The best part, is that my students didn't mind working this hard, after all, they got a reward for getting four-in-a-row.
