By the end of this lesson, your students will be able to multiply whole numbers by multiples of 10.  The lesson begins with a review of the commutative property and the accompanying vocabulary, such as factors.  Not only will students understand the concept of multiplying by 10, they will also gain a useful skill for completing math problems in their heads rather than having to write the equations out by hand.

Classroom Procedure:

  1. Begin by explaining to students that the commutative property of multiplication means that you can move the factors around to make multiplying numbers easier. Remind them that it doesn’t change the value of the numbers, just the order in which you multiply.
  2. While reading the content pages, reinforce vocabulary and give students additional examples of multiplication of multiples of 10 problems in order to help them practice the new algorithm.  Use the additional resources to enhance understanding.
  3. Introduce the notes on multiplication of multiples of 10. Have students practice problems by using the commutative property of multiplication.  Use the additional resources to enhance understanding.
  4. Have students practice problems and show their work on how they broke apart the multiple of ten into a multiplication fact.
  5. Follow Activity page with students. Have students play individually as the teacher calls out the expressions.  Students can make a new board each time for multiple games.  Consider having a small prize for the students who win.
  6. Distribute Practice page. Check and review the students’ responses as a class.
  7. Distribute the Homework page. Have students work a few problems at the beginning of the next class to reinforce the algorithm.
  8. In closing, ask students if they are able to do the computations in their head.
  9. Allow for responses and discussion.
