Relating Multiplication and Division: Tips and Tricks

  • Have graph paper available for students to use when they draw arrays. It will help them keep the objects in rows and columns lined up.
  • Divide the class into groups with a different number of students in each group. Call one group to the front of the class and have the members of that group sit down, arranging themselves in an array. Ask a volunteer to name related multiplication and division sentences that describe the array. Repeat this activity with the other groups of students.
  • Keep a supply of counters and small paper plates on hand for students to use when they model division.
  • Make multiple copies of the number lines on Learning Tool 5 in the Learning Tools Folder. Students can use the number lines to model division as repeated subtraction.
  • Two or more students can play Multiplication and Division Concentration. Write a multiplication sentence such as 4 x 4 = 16 on each of eighteen index cards. Write the related division sentences on eighteen more cards. Arrange the cards facedown in a 6 x 6 array. Players take turns matching related number sentences. The player with the greatest number of matches wins the game.
