Unit 4, Lesson 3
The Relationship of Multiplication and Addition
EngageNY 45 min(s)
Students build and clarify the relationship of multiplication and addition by evaluating identities such as 3g = g + g + g. Students continue to use the squares from Lessons 1 and 2 to create tape diagrams. Write two different expressions that can be depicted by the tape diagram shown. Provide each pair of students with a collection of 30 squares, which they use to create tape diagrams throughout the lesson.
