Grade 5 Math: Fractions: Final Exam Review

Final Exam Review Guide Comprehensive review mixing skills from the whole unit. Use this set the week before a major test. ## Unit checklist Work through every section below, then take the final exam quiz. Understanding Fractions as Parts of a Whole A fraction names a part of a whole or a part of a set. The numerator tells how many parts you have, and the denominator tells how many equal parts make the whole. One half means one of two equal parts. Visual models like fraction bars and number lines help students see that 3/4 and 6/8 can represent the same amount even when the numbers look different. Equivalent Fractions Equivalent fractions have different numerators and denominators but the same value. Multiply or divide both the numerator and denominator by the same number to find an equivalent fraction. For example, 2/3 equals 4/6 and 6/9. Simplifying a fraction means dividing top and bottom by their greatest common factor until no common factor remains. Comparing and Ordering Fractions When denominators match, compare numerators. When denominators differ, find a common denominator or use benchmark fractions like 1/2. A fraction greater than 1/2 has a numerator more than half the denominator. Number lines show that 3/8 is less than 1/2 while 5/8 is greater than 1/2. Adding and Subtracting Fractions Fractions must share a common denominator before you add or subtract. Rewrite each fraction using the least common denominator, then add or subtract the numerators and keep the denominator. Simplify the answer when possible. In word problems, identify what operation fits the story before computing.
