Fill-in-the-blanks walk fourth graders through finding the LCD of 4 and 6, rewriting 3/4 and 5/6 over 12 to compare them, converting 2 4/9 to an improper fraction, simplifying 18/30, and comparing 4/7 with 3/5 using >, <, or =. Later items handle 17/6 as a mixed number and the LCD of 9 and 12.
A matching round pairs 5 1/3, 3 3/8, 2 2/7, and 4 1/6 with their improper-fraction twins (16/3, 27/8, 16/7, 25/6). The LCD work and mixed-number conversions get students fluent in the moves comparison problems demand.
