Description

The lesson provides the specific steps to multiplying large numbers.  The steps are known as an algorithm, and the algorithm can be applied any time your students need to multiply large numbers.  Several problems are included with the lesson so your students can practice using the steps.

Sample Classroom Procedures: 

  1. Begin by explaining to students that multiplying large numbers has very specific steps that are followed each time and this is called an algorithm.
  2. While reading the content pages, reinforce vocabulary and give students additional examples of large multiplication problems in order to help them practice the new algorithm.  Use the additional resources to enhance understanding.
  3. Introduce the notes on multiplying larger numbers. Have students practice problems with one, two, and four digits.  Use the additional resources to enhance understanding.
  4. Have students practice problems while repeating the steps out loud to a partner.
  5. Follow Activity page with students. Have students work individually.  They should come to the front of the room, shake the bag (or box), choose two numbers, multiply them, and then return the numbers to the bag before drawing again.
  6. Distribute Practice page. Check and review the students’ responses as a class.
  7. Distribute the Homework page. Extend the homework to have students look at how much they eat in a week or have them create a menu for lunch or dinner.
  8. In closing, ask students to repeat the four steps used in multiplying large numbers.
  9. Allow for responses and discussion.
