few_shots: 
Example 1:
Concept/skill: 
Represent addition and subtraction with objects, fingers, mental images, drawings (Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

Problem/activity:
Task
Materials
One 10-frame per pair of students (see example below)
[IMG]
Counters, 10 per pair of students
Decks of number cards 0-5 (with 4 of each number) or two 0-5 dice
Setup
This activity is done in pairs. The students sit side by side with 10-frame and deck of cards or dice. If they have cards, the cards are shuffled and placed face down in front of them.
Action
Player 1 flips a card or rolls the die. They place that many counters on the 10-frame. Player 2 flips a card or rolls the die. They place that many more counters on the 10-frame next to the counters already on the ten frame. The students count the total together.
A recording sheet can be added when the students have been introduced to equations and number sentences. For those students who can handle higher numbers, a deck of 0-10 cards and two 10-frames can be used.
This game can also be played alone.


Answer: 
Yes. This task involves representing addition with objects such as number cards and dice.

Example 2:
Concept/skill: 
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
 Grade 3 expectations in this domain are limited to fractions with denominators 2, 3, 4, 6, and 8.

Problem/activity:
Task
 Arrange the fractions in order from least to greatest. Explain your answer with a picture.
 $\frac{1}{5}, \frac{1}{7}, \frac{1}{3} $
 $\frac{2}{5}, \frac{2}{7}, \frac{2}{3} $
 $\frac{5}{6}, \frac{3}{6}, \frac{1}{6} $
 $\frac{5}{12}, \frac{8}{12}, \frac{4}{12} $

Answer: 
No. Completing this task does not involve representing fractions on a number line diagram.

Example 3:
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, assess whether the following problem or activity is 'aligned' with the given Common Core standard in Mathematics.

standard_description: Analyze and solve pairs of simultaneous linear equations.
problem_activity: Activity
The purpose of this activity is for students to practice graphing and making sense of the graphs of systems of equations. Students construct equations from descriptions of situations, graph those equations, then consider points on the graph in context. This will be useful in their Algebra class when students write their own system of equations to represent situations.
If students are proficient at graphing lines, consider providing access to graphing technology to focus student work on the creation of the equations and interpretation of the results.

A ride sharing company offers two options: riding in small cars that can carry up to 3 passengers each, or riding in large vans that can carry up to 6 passengers each. A group of 27 people is going to use the ride sharing service to take a trip. The trip in a small car costs

An equation that represents one of the constraints is
\(3x+6y=a\)
.
What is the value of
\(a\)
?
What do
\(x\)
and
\(y\)
represent?
An equation that represents the other constraint is
\(cx+15y=80\)
. What is the value of
\(c\)
?
[IMG]
Here is a graph that represents one of the constraints. Which one? Explain how you know.
Sketch another line on the graph that represents the other constraint.
For each coordinate pair, describe its meaning in the situation and decide whether it satisfies the constraint on total number of people, the constraint on cost, or neither.
\((2,4)\)

At what point do the two lines intersect? What does this point mean in this situation?

Activity Synthesis
The purpose of the discussion is to understand the connection between the situation and the equations as well as understanding the meaning of points on one of the lines, on both of the lines, or on neither of the line in context.
Display the graph showing both lines as well as the points from the activity.
[IMG]
Ask students, "How can the graph help you determine whether a point will fit one of the situations, both of the situations, or neither? How can the equations help you determine the same thing?" (On the graph, we can see if a point is on one of the lines, on both of the lines, or on neither of the lines. If it is on a line, it fits with that situation. From the equations, we can substitute in the
\(x\)
- and
\(y\)
-values to determine whether the values make the equation true or not. If the equation is true, the values fit with that situation.)
