Task
Cruz and Erica were both getting ready for soccer.
Cruz ran 1 lap around the school.
Erica ran 3 laps around the playground.
Erica said,
I ran more laps, so I ran farther.
Cruz said,
4 laps around the school is 1 mile, but it takes 12 laps around the playground to go 1 mile. My laps are much longer, so I ran farther.

Concept/skill: 
Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.

Answer: 
No. This task does not involve comparing decimals to hundredths. Instead, it involves fraction comparisons.

Now, does the problem or activity shown below enable students to learn the full intent of the following concept or skill?

standard_description: Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
problem_activity: Narrative
The purpose of this activity is for students to connect story problems to the equations that represent them and to solve different types of story problems. Students identify equations with a symbol for the unknown that match a story problem and justify their decisions by describing how the equations represent the quantities and any actions in the story problem (MP4). When students analyze and connect the quantities and structures in the story problems and equations, they are thinking abstractly and quantitatively (MP2) and making use of structure (MP7).
MLR8 Discussion Supports.
Display sentence frames to support discussion as students explain their reasoning to their partner: “I noticed ___ , so I matched . . .” Encourage students to challenge each other when they disagree.

Required Materials
Materials to Gather
Base-ten blocks
Materials from a previous lesson
Materials to Copy
Equations for Different Types of Word Problems
Required Preparation
Create a set of cards from the blackline master for each group of 2
–
4.
Each group of 2
–
4 needs a set of cards from the previous lesson.
Launch
Groups of 2
–
4
Give each group the story problems (Cards A–I) from the Story Problem and Diagram Cards.
Give one set of Equation Cards to each group of students.
Give each group access to base-ten blocks.
“Take turns reading the story problems. After one person reads, work together to find an equation that matches. When you think you have found a match, explain to your group why the cards match.”
“If you think that more than one card could match the story, explain the match to your group.”
As needed, demonstrate the activity with a student volunteer.
“When your group finishes, choose 2 story problems from Cards F, G, H, or I and solve them.”
Activity
6 minutes: partner work time
Monitor for students who explain why more than one equation may match a story and how the equations match the quantities in the context of the story problem.
4 minutes: independent work time
Student Facing
Match each story problem with an equation. Explain why the cards match.
Choose 2 story problems and solve them. Show your thinking.

Advancing Student Thinking
Students may believe that only one equation could match each story. Encourage
students to describe how equations match any actions in the story and whether any other equations show the same actions. If there are no actions in the story, ask students to explain why one or more cards shows the relationship between the parts and the whole. Consider providing the tape diagrams from the previous activity to support students in their explanations.
Activity Synthesis
Invite students to share a match for each story.
Consider asking:
“How does the equation match the story problem?”
“Is there another equation that could match the story problem? Explain why or why not.”
