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} $

Description: 
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.

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

Now, assess whether the following problem or activity aligns with the provided description.

standard_description: Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
problem_activity: Narrative
The purpose of this activity is for students to practice adding within 1,000 with an emphasis on adding by place. Throughout the activity, students have opportunities to explain their methods and representations to peers. In the synthesis, students have opportunities to question and critique the work of their peers as they compare different methods for adding three-digit numbers and different representations that show composing units when adding by place (MP3).
This activity uses
MLR8 Discussion Supports
. Advances: conversing
Engagement: Provide Access by Recruiting Interest.
Provide choice. Invite students to decide which problem to start with and the strategy they feel most comfortable solving with.
Supports accessibility for: Social-Emotional Functioning, Organization, Attention
Required Materials
Materials to Gather
Base-ten blocks
Launch
Groups of 2
Give students access to base-ten blocks.
Activity
“We are going to practice adding 2 three-digit numbers. You can find the value of each sum in any way that makes sense to you. After some time working independently, you can continue working with a partner.”
MLR8 Discussion Supports
Display sentence frames to support students when they explain their strategy:
“First, I _____ because . . .”
“I noticed _____ so I . . .”
5 minutes: independent work time
4 minutes: partner work time
“Choose one expression and share how you found the value of the sum with a new partner.”
3 minutes: partner discussion
Monitor for students who use base-ten blocks, base-ten diagrams, or other representations that clearly show adding by place.
Student Facing
Find the value of each expression. Show your thinking.
\(384 + 409\)
\(757 + 152\)
\(262 + 438\)
\(575 + 166\)

Advancing Student Thinking
If students lose track of the tens or hundreds they compose (for example,
\(384 + 409 = 783\)
) or do not compose a ten or hundred, prompt students to explain their thinking and any representations they use. Consider asking:
“How does your representation show that you composed a new unit?”
“What could you add to your representation to help you keep track of any tens or hundreds you compose?”
“How could you use base-ten blocks to show your thinking?”
Activity Synthesis
Invite 2–3 previously identified students to share their representations and how they found the value of the sums.
“How are these methods the same? How are they different?”
