Concept/skill: 
Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.

 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.

Answer: 
No. This activity does not involve addition or subtraction, or unknowns in different positions of equations or drawings.

Now, determine whether the following problem or activity can enable students to understand the concepts or skills in the provided description.

standard_description: Use place value understanding to round multi-digit whole numbers to any place.
Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.
problem_activity: Narrative
The purpose of this activity is to use the standard algorithm to add multi-digit numbers, taking care to compose a new unit and record it accurately. They also analyze common errors and critique the given reasoning when composing a new unit (MP3).

“Complete the first 2 problem and then talk to your partner about any patterns you notice.”
Activity
3 minutes: independent work time
2 minutes: partner discussion
Share and record responses.
If needed, use the expanded form to help students make connections between the way composing a larger unit is recorded when using the standard algorithm and what is happening in each place. In the bottom line of the example here, we see 10 in the ones place and 100 in the tens place. Both partial sums do not match the assigned values of their places.

Use the expanded form of both 8,299 and 1,111 to check the value you found for the last sum.
Each computation shown has at least one error. Find the errors and show the correct calculation.

Advancing Student Thinking
Students may need support identifying errors in the last problem. Consider asking: “How might subtraction be used to help identify the error?”
Activity Synthesis
Ask students to share the errors they identified in the last set of questions.
“What are some common errors when adding large numbers?”
