Subtracting fractions with unlike denominators can be overwhelming, but in this task, 5th graders work systematically to break down the procedure through three questions. The first two questions ask for pictures to be drawn along with evaluating the subtraction sentences to illustrate why finding a common denominator is important. The third and final question allows for subtraction of an improper fractions without pictures. The activity includes a commentary and a solution page that replaces a traditional lesson plan and provides valuable insight for teachers in order to smoothly implement the lesson in the classroom.
