Great review for converting mixed numbers and improper fractions! It works great as a center, an "early finishers" game, or a whole class activity.
Two gameboards and directions are provided.
Each player has a gameboard (either with mixed numbers or improper fractions) and bingo chips. Players try to find each other's hidden bingo chip "battleships" as they use their knowledge of converting mixed numbers to improper fractions and vice versa.
