Teaching notes
Pacing: 10 minutes for entire activity
This entire activity spans 6 cards. This is card 5 of 6. Activity Synthesis
Select students who have used the following approaches in the given order:
Recognize that to move from the rst column to the second, you multiply by 3.
Say that 3 is the constant of proportionality.
Recognize that the equation can be used to nd the constant of proportionality algebraically.
Say that the 3 can be interpreted as the number of people per 1 cup of rice.
If no student sees that these insights are connected to prior work, explicitly connect them with the lessons of the previous two days.
The activity synthesis continues on the following card.
Support for English Language Learners
Lighter Support: MLR 7 (Compare and Connect). As students explain their dierent approaches to completing the tables, ask "What is similar, what is dierent?" about their methods. For question 1, connect the dierent approaches by asking "Where do you see the 3 in each approach?"
