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} $

Topic options: 
A. Ratios & Proportional Relationships: students learn to recognize, describe, represent, and reason with ratios, rates, proportional relationships, and percent.
B. Geometry: students learn to classify geometric figures by their properties, and understand and compare the relationships between them. Students develop and use formulas to compute lengths, areas, and volumes, and they use transformations to generate new shapes and compare existing ones. Geometry can be studied with and without coordinates.
C. Statistics & Probability: students learn to analyze and produce data distributions, and build understanding of univariate and bivariate data. They learn to interpret data, make statistical inferences, justify conclusions, understand rules of probability, and use probability to make decisions.
D. Modeling: students learn to choose and use appropriate mathematics and statistics to analyze real-world empirical situations, improve decisions, and report on their conclusions and the reasoning behind them.
E. Operations & Algebra: students learn to solve problems using algebraic thinking and operations such as addition, subtraction, multiplication, and division. They may learn to identify and explain arithmetic patterns, evaluate or manipulate numerical expressions, and reason with equations and inequalities.
F. Number & Operations in Base Ten: students learn to work with the base-ten system and build place value understanding.
G. Number & Operations - Fractions: students learn to understand fractions as numbers and may work with them using addition, subtraction, multiplication, and division.
H. Functions: students learn to define, use, and evaluate functions to model relationships between quantities.
I. Measurement & Data: students learn to work with data and measure attributes such as time, money, length, area, and volume. They may learn to compare measurements to operations and convert between different units of measure.
J. Counting & Cardinality: students learn to know number names and the count sequence, count to tell the number of objects, and compare numbers.
K. Number Systems and Quantity: students learn to understand the complex number system and reason quantitatively.

problem_activity: Activity
The purpose of this task is for students to understand that for a given number, numbers to the left are always less than the number, and numbers to the right are always greater than the number. The precise use of the term “absolute value” is not expected at this time.
Teacher Notes for IM 6–8 Accelerated
During the activity synthesis, introduce the terms
opposite
and
rational number
. Two numbers that are the same distance from zero on the number line are called opposites. Rational numbers are fractions and their opposites.
Digital
Launch
Allow 10 minutes quiet work time followed by whole-class discussion.
Students using the digital materials can graph the points and check them with the applet. Marks at each half, quarter, and eighth of a unit can be shown to help plot the points or to self-check for accuracy.
Representation: Internalize Comprehension.
Activate or supply background knowledge about equivalent fractions. Some students may benefit from access to pre-prepared number lines to compare fractions for the final two problems.
Supports accessibility for: Conceptual processing; Organization

Plot the numbers -2, 4, -7, and 10 on the number line. Label each point with its numeric value.
[IMG]
Decide whether each inequality statement is true or false. Be prepared to explain your reasoning.
\(\text-2 < 4\)
\(\text-2 < \text-7\)
\(4 > \text-7\)
\(\text-7 > 10\)
Drag each point to its proper place on the number line. Use your observations to help answer the questions that follow.
Andre says that
\(\frac14\)
is less than
\(\text{-}\frac {3}{4}\)
because, of the two numbers,
\(\frac14\)
is closer to 0. Do you agree? Explain your reasoning.
Answer each question. Be prepared to explain how you know.
Which number is greater:
\(\frac14\)
or
\(\frac54\)
?
Which number is farther from 0:
\(\frac14\)
or
\(\frac54\)
?
Which number is greater:
\(\text{-}\frac {3}{4}\)
or
\(\frac58\)
?
Which number is farther from 0:
\(\text{-}\frac {3}{4}\)
or
\(\frac58\)
?
Is the number that is farther from 0 always the greater number? Explain your reasoning.

Anticipated Misconceptions
Some students may have difficulty comparing numbers on the negative side of the number line. Have students plot the numbers on a number line from least to greatest. It may be helpful to provide an example that students can use as a visual aid while they are working independently.
Some students may have difficulty comparing fractions in question 4. Remind them that comparing fractions is easier using a common denominator. Suggest that they subdivide the interval from 0 to 1 into fourths or eighths.
Activity Synthesis
The key takeaway from the discussion is that now that we have numbers on both sides of 0, distance from 0 isn’t enough to compare two numbers. Instead, we call numbers farther to the left on the number line “less” and numbers farther to the right “greater.” Display the following number line for all to see:
[IMG]
One inequality at a time, ask students to indicate whether they think each of the following is true or false:
\(\frac54 > \text{-}\frac {3}{2}\)
(true)
\(\frac54\)
is farther from 0 than
\(\text{-}\frac {3}{2}\)
(false)
\(\text{-}\frac {3}{2} < \text{-}\frac {3}{4}\)
(true)
\(\text{-}\frac {3}{2}\)
is farther from 0 than
\(\text{-}\frac {3}{4}\)
(true)
Invite students to share their reasoning. Here are some sentence frames that might be helpful:
“__ is greater (less) than __ because __.”
“__ is farther from 0 than __ because __.”
Speaking: MLR2 Collect and Display.
During the class discussion, record and display words and phrases that students use to explain why they decided certain inequality statements are true or false. Highlight phrases that include a reference to “to the right of,” “to the left of,” and a distance from zero. If students use gestures to support their reasoning, do your best to connect words to the gestures.
Design Principle(s): Optimize output (for explanation); Support sense-making
