Bring fraction skills to real life. Multiple-choice problems track a painter using 2 1/3 and 1 3/4 gallons from a 5-gallon bucket, an 8 1/2-foot rope cut into 2 3/8 ft and 3 1/6 ft pieces, an expression matching 1 1/6 (it's 3/4 + 5/12), and the gap between Emma's 3 2/5 miles and Zoe's 2 7/10 miles.
Fill-in-the-blanks add 2 1/4 cups flour and 1 2/3 cups sugar, subtract 2 5/6 ft from a 6 3/8 ft board, total 3/4 hour piano plus 5/6 hour guitar, find how much oil is left after 1/3 of 7/8 cup, and compare 4 1/5 and 2 3/4 liters. Fifth graders see why finding common denominators actually matters outside the textbook.
