(Show image) Explain how this shows 3 rows with 6 dots in each row, representing 3 × 6.

Check student work and have them do the same for a new problem (ex: 4x7).

Problem at Hand

What is 3x6? How can we show it through drawings or figures?

Take 1-2 minutes to try it on your own. Show your work.

(Student responses may vary: repeated addition, drawing 3 rows of 6 dots, etc.)

Think-Pair-Share: Students will first think independently about the problem, then pair up to discuss their thoughts. After this, it's time to share with the class.

Multiple Representations: Have students represent the multiplication problem in different ways: arrays, drawing pictures, and writing equations.

Guided Questions: Ask scaffolded questions to lead students to discover the relationships between the multiplication of the numbers/objects.

Students will submit an exit ticket before leaving class, which will be graded to identify areas needing reteaching.

Example Exit Ticket: How would you represent 8x6 through drawings or figures? Be creative!

Students who finish early can add contributions to the class anchor chart.
