Concept/skill: 
Fluently add and subtract multi-digit whole numbers using the standard algorithm.
Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.

Problem/activity:
Problem 1
Solve using the standard algorithm. If you get stuck, use an area model and/or the partial products algorithm to help. Then assess the reasonableness of your answer.
a.
$$5,803\times46$$
b.
$$63\times2,116$$
Problem 2
Dunkin' introduced a croissant doughnut in 2014. In the first three months of its debut, they sold 7,870 dozen of them per day. How many croissant doughnuts were sold in the first three months?


Answer: 
No. This set of problems does not directly involve adding or subtracting multi-digit whole numbers. Instead, it focuses on multiplying multi-digit whole numbers.

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

standard_description: Determine the unknown whole number in an addition or subtraction equation relating to three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = �� – 3, 6 + 6 = ��.
problem_activity: Narrative
This warm-up prompts students to visualize the idea of arranging angles around a point and adding their measurements as more pieces are added. The angles are familiar angles:
\(90^\circ\)
,
\(180^\circ\)
, and
\(270^\circ\)
. Students previously arrived at these benchmarks by decomposing a full turn or
\(360^\circ\)
. Here, they compose a full turn from
\(90^\circ\)
angles.
The work here familiarizes students with the context and mathematics that might be involved later in the lesson. In the subsequent activities, students will compose and decompose paper cutouts of angles to determine angle measurements.

Activity Synthesis
“What angles do you think are the measurement of each angle?” (They look like
\(90^\circ\)
,
\(180^\circ\)
, and
\(270^\circ\)
angles.)
“How do you know?” (If the paper is a rectangle, then the corner pieces are right angles or
\(90^\circ\)
each. Two of the corner pieces would be
\(90+90\)
. Three pieces would be
\(90+ 90+90\)
.)
“What angle would we get if we add the last corner piece?” (
\(360^\circ\)
)
