Problem/activity:
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, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.
problem_activity: Narrative
In this activity, students recall what they know about division from grade 3. The context allows students to connect lived experiences to the math of the activity. By inviting students to consider treats that they enjoy in their homes or neighborhoods, they share experiences and foster connections that build community.
The first question gives students an opportunity to co-craft mathematical questions based on a situation before answering a question based on a division equation. Students divide a two-digit number by a one-digit divisor, as they did in grade 3, in a way that makes sense to them. The activity synthesis highlights different representations students made and relates them to the situation. The term
dividend
is re-introduced in this lesson to describe a number being divided into equal groups.
This activity uses

MLR 5: Co-craft Questions
Display the opening paragraph and the first question.
“Write a list of mathematical questions that could be asked about this situation.”
2 minutes: independent work time
2–3 minutes: partner discussion
Invite several students to share one question with the class. Record responses.
“How are these questions alike?” (The questions involve multiplying or dividing.) “How are they different?” (The questions can be answered using different operations.)
“Let’s look at the next question in the activity.”

Student Facing
Diego’s aunt is buying paletas, which are ice pops, for a class party. At the local market, paletas come in different flavors. She buys the same number of paletas of each flavor.

What mathematical questions can we ask about this situation?
Here is an equation:
\(84 \div 7 = {?}\)
In the situation about the class party, what questions could the equation represent?
Find the answer to one of the questions you wrote. Show your reasoning.

Advancing Student Thinking
If students are unsure how to write a division question for
\(84 \div 7\)
, consider asking:
“If you were to act out the meaning of this expression, what would you do?”
“If you were to explain its meaning, what would you say?”
“In what type of situations would these types of actions take place?”
Activity Synthesis
Display two questions that students wrote for the equation
\(84 \div 7 = {?}\)
.
“What does the 84 represent in both problems?” (The amount being divided into equal groups.)
“In mathematics, the number being divided is known as the
dividend
.”
Invite students to share their strategies for the last question. Highlight strategies that show equal-size groups and reasoning that relates multiplication and division.
