problem_activity: Narrative
In this activity, students use the context of paper flowers to analyze patterns and solve multi-step problems. The patterns are fairly straightforward, but to use them to solve problems, students will need to represent or otherwise reason about them mathematically. Their earlier experience of making flowers supports students in making sense and visualizing each step of the problem.
MLR7 Compare and Connect.
Synthesis: After all strategies have been presented, lead a discussion comparing, contrasting, and connecting the different approaches. Ask, “Did anyone solve the problem the same way, but would explain it differently?” and “Why did the different approaches lead to the same (or different) outcome(s)?”
Advances: Representing, Conversing

[IMG]
Priya and Jada are making paper flower garlands for their friend’s quinceañera. Each garland uses 12 flowers.
Priya wants 2 big flowers, followed by 2 small flowers. Jada wants 1 big flower, followed by 2 small flowers. Use their patterns to draw the garlands.
Priya and Jada make 25 garlands of each type. How many large and small flowers will they need altogether?
Diego and Kiran also made flowers. They made a total of 155 flowers for garlands that require 16 flowers each. How many garlands can they make?
It takes 1 minute to cut the strips for a flower and 2 minutes to finish it. How long did it take Diego and Kiran to make the 155 flowers, if they each make about the same number of flowers?

“What specific part of the work makes their explanation clear?”
Consider asking:
“What suggestion do you have to make it clearer?”
“How can you revise your own work to make it more clear or organized?”
