Let’s represent situations that involve “times as many.”
Warm-up Notice and Wonder: Compare Cubes
What do you notice? What do you wonder?
Activity 1 Twice as Many
Andre has some cubes. Han has twice as many cubes as Andre.
Use cubes, pictures, or other diagrams to show how many cubes Andre could have and how many cubes Han could have.
Be prepared to explain how your representation shows that Han has twice as many cubes.
Activity 2 Times as Many

Andre has the following cubes and Han has 4 times as many.
Priya has the following cubes and Jada has 6 times as many.
Tyler has the following cubes and Mai has 8 times as many.
What number represents “8 times as many as 2”? Show your reasoning.
