Task
 Arrange the fractions in order from least to greatest. Explain your answer with a picture.
 $\frac{1}{5}, \frac{1}{7}, \frac{1}{3} $
 $\frac{2}{5}, \frac{2}{7}, \frac{2}{3} $
 $\frac{5}{6}, \frac{3}{6}, \frac{1}{6} $
 $\frac{5}{12}, \frac{8}{12}, \frac{4}{12} $

Topic options: 
A. Ratios & Proportional Relationships: students learn to recognize, describe, represent, and reason with ratios, rates, proportional relationships, and percent.
B. Geometry: students learn to classify geometric figures by their properties, and understand and compare the relationships between them. Students develop and use formulas to compute lengths, areas, and volumes, and they use transformations to generate new shapes and compare existing ones. Geometry can be studied with and without coordinates.
C. Statistics & Probability: students learn to analyze and produce data distributions, and build understanding of univariate and bivariate data. They learn to interpret data, make statistical inferences, justify conclusions, understand rules of probability, and use probability to make decisions.
D. Modeling: students learn to choose and use appropriate mathematics and statistics to analyze real-world empirical situations, improve decisions, and report on their conclusions and the reasoning behind them.
E. Operations & Algebra: students learn to solve problems using algebraic thinking and operations such as addition, subtraction, multiplication, and division. They may learn to identify and explain arithmetic patterns, evaluate or manipulate numerical expressions, and reason with equations and inequalities.
F. Number & Operations in Base Ten: students learn to work with the base-ten system and build place value understanding.
G. Number & Operations - Fractions: students learn to understand fractions as numbers and may work with them using addition, subtraction, multiplication, and division.
H. Functions: students learn to define, use, and evaluate functions to model relationships between quantities.
I. Measurement & Data: students learn to work with data and measure attributes such as time, money, length, area, and volume. They may learn to compare measurements to operations and convert between different units of measure.
J. Counting & Cardinality: students learn to know number names and the count sequence, count to tell the number of objects, and compare numbers.
K. Number Systems and Quantity: students learn to understand the complex number system and reason quantitatively.

problem_activity: Narrative
The purpose of this activity is for students to solve two-step problems without the scaffold of having the first step explicitly stated. Students solve in a way that makes sense to them and might use diagrams to help them make sense of the story. In the synthesis, the tape diagram is highlighted.
MLR7 Compare and Connect.
Synthesis: Invite group to prepare a visual display that shows the strategy they used to solve the story problems. Encourage students to include details that will help others interpret their thinking. For example, using labels, notes, diagrams, or drawings. Give students time to investigate each other’s work. During the whole-class discussion, ask students, “What did the representations have in common?”, “How were they different?” and “Did anyone solve the problem the same way, but would explain it differently?”
Advances: Representing, Conversing
Launch
Groups of 2
“With a partner, choose a problem from the first activity to solve. Discuss how the diagram can help you think about the problem.”
4 minutes: partner work time
Activity
“Now you will be solving a few money problems on your own.”
“Use a diagram if it helps you make sense of the story.”
10 minutes: independent work time
Monitor for students who use a diagram to represent and solve the problem about Tyler, Andre, and Noah.
Student Facing
For each problem, show your thinking. Write your final answer using the \$. Use a diagram if it helps.
Mai has \$27, Elena has \$48, and Jada has \$16. How much money do they have altogether?
Tyler has \$45, Andre has \$36, and Noah has \$28. How much less money does Tyler have than Andre and Noah combined?
Lin has \$19. Together, Lin and Han have \$45. Then Han gets \$17 more. How much money does Han have now?

Advancing Student Thinking
If students want to represent the story with a diagram or equation but need support to start, consider asking:
“What is the story about? How could you break the problem into smaller parts?”
“How could you use a diagram or equation to represent the smaller parts?”
Activity Synthesis
Invite previously identified students to share the diagram for comparing Tyler's money to Andre's and Noah's money.
“How does this diagram represent the story?” (It shows Tyler's amount and then the combined amount of Andre and Noah. I can see that Tyler has less than Andre and Noah and that I need to add Andre's amount and Noah's amount and then subtract Tyler's amount from that.)
