Convert a fraction to a decimal, a decimal to a fraction; add, subtract, and multiply fractions; and find for greater, less than, or equal to all with this creative set of flashcards. Each card features a double level design with a problem presented above and an attached paper door below that hides the answer. Use on the overhead for full class visibility and participation or use them as traditional flashcards. Students should understand the least common denominator to solve each problem.
