Multiplication Number Sentences

To complete the lesson, students will need to refer to the Patterns for Remembering the Facts class chart that they began in Lesson 3. At that time, they described the patterns for multiplication with 0, 1, 2, 5, and 10. In Lesson 4, the class added patterns for the turn-around facts and square numbers. Then, in Lesson 5, they added the patterns for the nines. See Figure 1 for a sample of a completed chart.
