This Instructional Activity is a part of the Lesson 9, Unit 5, Grade 7. In this optional activity, students revisit the representation of a multiplication chart, which may be familiar from previous grades; however, in this activity, the multiplication chart is extended to include negative numbers. Students identify and continue patterns to complete the chart and see that it fits the patterns in the chart for the product of two negative numbers to be a positive number.
