Concept/skill: 
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
 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: 
Yes. By arranging the fractions in this problem, students learn to compare fractions by reasoning about their size.

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

standard_description: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction 1/2/1/4 miles per hour, equivalently 2 miles per hour.
problem_activity: Problem 1
Two similar situations are shown below. How are they similar and how are they different?
A pair of sneakers regularly cost $40. They are on sale for 25% off. How much money will you save?
A pair of boots are on sale for $40 off. This is a savings of 25%. What is the regular price of the boots?
Problem 2
The Alden Middle School has a girls’ soccer team and a boys’ soccer team.
The girls’ soccer team won 80% of its games this season. They won 12 games.
The boys’ soccer team won 70% of its games this season. They won 14 games.
How many games did each soccer team play this season?
Problem 3
You’ve poured 84 gallons of water from a hose into a small pool. The pool is 35% filled with water. How many gallons of water can the pool hold if it is completely filled?
