Subtracting fractions. In this collaborative activity students subtract fractions by first coloring portions of circles to show the two fractions, then subtracting the fractions and finally showing the difference as a picture and as a fraction. All problems have unlike denominators that are related so that only one denominator needs to be changed in order for the two fractions to have a common denominator. Once a pennant is complete, it can be hung along a string in your classroom to show the world that, "Hey, we know how to subtract fractions!"
Fractions range from halves to sixteenths.
Included are 20 pennants with fraction subtraction problems, an optional student answer sheet and an answer key. Each group of students can be given a set of pennants, crayons, scissors and either glue, tape or a stapler. Students can be in charge of cutting out the pennants. Groups can compete to see which group can complete the most pennants or your entire class can add pennants to one string as they complete each one.
