Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP5.
Use appropriate tools strategically.
MP6.
Attend to precision.

In this Workshop, students focus on developing strategies for solving the multiplication facts. Students discuss strategies they have developed for the multiplication facts, decide which facts strategies still need to be developed, and learn a game that can be used to practice their multiplication facts.

Content in this Lesson

  • Represent multiplication and division problems with number lines, drawings, rectangular arrays, and number sentences [E1].
  • Use strategies to solve multiplication problems [E2].
  • Use and explain the multiplication properties of 0 and 1 to solve multiplication problems [E3].
  • Use turn-around facts to solve multiplication problems [E4].
  • Identify and use patterns to solve the multiplication facts for the 2s, 3s, 5s, 10s, 9s, and square numbers [E5].
  • Reason from known facts to solve multiplication facts [E2].
  • Use break-apart products to solve multiplication facts [E6].

Materials for Teachers

Prepare Strategy Charts. Prepare 5 sheets of chart paper to display multiplication fact strategies. Label each with a Multiplication Fact Group: “Fives and Tens,” “Twos and Threes,” “Nines,” “Square Numbers,” and “Zero and One.”

Prepare a Bulletin Board Space. Prepare a bulletin board space to display multiplication fact strategies. For future reference, display the strategy charts made in this lesson. You may also choose to display a variety of solution strategies. Student can then reference these strategies in later units as they develop efficient strategies for their multiplication facts.

E1.
Represent multiplication and division problems with number lines, drawings, rectangular arrays, and number sentences.
E2.
Use strategies to solve multiplication and division problems (e.g., skip counting, repeated addition, repeated subtraction, reasoning from known facts, and invented).
E3.
Use the multiplication properties of 0 and 1 to solve multiplication problems.
E4.
Use turn-around facts to solve multiplication problems (applying the commutative property of multiplication).
E5.
Identify and use patterns to solve the multiplication facts for the 2s, 3s, 5s, 10s, 9s, and square numbers.
