Dividing fractions. In this collaborative activity students divide fractions by finding missing lengths of rectangles given area and height. This links fraction division to the area model to make the concept more concrete. Students need to change mixed numbers to improper fractions first before dividing. The answer key gives answers in mixed number form. You may ask your students to give answers in mixed numbers or improper fractions.
Units of measure are in cm, m and km.
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 divide fractions!"
Included are 20 pennants with fraction division 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.
