Narrative
The first partner spins to get a group of coins. They write a question that compares the amount they spun to a different group of coins that they make up.


Standard options: 
A. Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
B. Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?


Your response, in json format:
{
  "explanation": "In this activity, students write word problems that compare coin amounts.",
  "answer": "B"
}

Now, assign the following problem or activity to one or more relevant standards it aligns with.

options: Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.

Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).

Fluently divide multi-digit numbers using the standard algorithm.
problem_activity: Optional activity
This optional activity is an opportunity to practice the methods in this lesson to calculate products of decimals, and students have an opportunity to practice multiplying decimals in a real-world context. Students can choose to use area diagrams to help organize their work and support their reasoning. However, the goal of the activity is to have students practice using the multiplication algorithm on decimals.
Launch
Give students quiet think time to complete the activity and then time to share their explanation with a partner. Follow with whole-class discussion.
Representation: Internalize Comprehension.
Activate or supply background knowledge. Provide students with access to a blank area diagram to support information processing.
Supports accessibility for: Visual-spatial processing; Organization
Student Facing
Calculate each product. Show your reasoning. If you get stuck, consider drawing an area diagram to help.
\((5.6) \boldcdot (1.8)\)
\((0.008) \boldcdot (7.2)\)
A rectangular playground is 18.2 meters by 12.75 meters.
Find its area in square meters. Show your reasoning.
If 1 meter is approximately 3.28 feet, what are the approximate side lengths of the playground in feet? Show your reasoning.

Are you ready for more?
Write the following expressions as decimals.
\(1-0.1\)
\(1-0.1+10-0.01\)
\(1-0.1+10-0.01+100-0.001\)
Describe the decimal that results as this process continues.
What would happen to the decimal if all of the addition and subtraction symbols became multiplication symbols? Explain your reasoning.

Activity Synthesis
Select students to share their strategies, being sure to highlight approaches using area diagrams and vertical calculations. Record the representations or strategies students share and display them for all to see.
Representing, Conversing: MLR8 Discussion Supports.
Use this routine help students prepare to share their strategies with the class. Give students time to discuss how they calculated each product for the first problem with a partner. Consider using this prompt to begin the conversation: “How did you use the multiplication algorithm to calculate the product of these two decimals? Provide a step-by-step explanation.” The listener should press for details by asking clarifying questions such as, “Why did you do that first?” and “Could you explain that a different way?” Allow each student an opportunity as the speaker and listener. This will help students build confidence in explaining the process of multiplying decimals before students are selected in the whole-class discussion.
