I recommend reviewing this with the entire class.
This is an updated version of the free product:
Fractions Review Sheet
This review sheet includes the following definitions and examples:
Least Common Multiple (LCM)
Least Common Denominator (LCD)
Greatest Common Factor (GCF)
Converting a Mixed Number to and Improper Fraction
Converting an Improper Fraction to a Mixed Number
Highly successful with my 5th graders in preparation for their test.
