Description

The lesson demonstrates to students how rectangles can be used to solve fraction multiplication problems. Examples are included showing two fractions being multiplied together, as well as a whole number being multiplied by a fraction. The lesson also demonstrates how to multiply the fractions without using drawings and still find the correct answer!

Classroom Procedure:

  1. Begin by explaining to students that they are going to use a rectangular diagram to multiply fractions.
  2. While reading the content pages, reinforce vocabulary and give students additional examples of fractions and rectangle problems in order to help them practice the new algorithm. Use the additional resources to enhance understanding.
  3. Introduce the notes on fractions and rectangles. Have students practice problems with and without whole numbers.  Use the additional resources to enhance understanding.
  4. Have students practice problems while drawing their own rectangles and fraction strips.
  5. Follow Activity page with students. Have students work individually to draw their bottle caps from the group bag, write down the problem, and put their caps back into the bag.
  6. Distribute Practice page. Check and review the students’ responses as a class.
  7. Distribute the Homework page. Have students share a few problems at the beginning of the next class to reinforce the algorithm.
  8. In closing, ask students to notice the pattern between the answer and the multiplication facts.
  9. Allow for responses and discussion.
