Concept/skill: 
Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.

Problem/activity:
Task
Cruz and Erica were both getting ready for soccer.
Cruz ran 1 lap around the school.
Erica ran 3 laps around the playground.
Erica said,
I ran more laps, so I ran farther.
Cruz said,
4 laps around the school is 1 mile, but it takes 12 laps around the playground to go 1 mile. My laps are much longer, so I ran farther.
Who is right? Draw a picture to help you explain your answer.


Answer: 
Yes. This task asks students to compare two fractions that are equal. The students need to explain why the two fractions are equal by drawing a picture, which involves using visual fraction models.

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

Can You Build It Stage 1 Directions

Narrative
One partner builds a rectangle so that their partner can’t see it. They describe the rectangle to their partner who tries to build the same rectangle. Students then compare their rectangles and switch roles. Students may choose to draw their rectangle on grid paper, rather than use inch tiles.
Variation:
Students may use more tiles to build their rectangles or may choose to build shapes made out of two rectangles.
Additional Information
Each group of 2 needs at least 48 inch tiles.
