Who’s on the Bus?
4.NF.2 - Task 5
Domain / Number & Operations- Fractions
Cluster /

Extend understanding of fraction equivalence and ordering.

Standard(s) / 4.NF.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
Materials / Paper and pencil, Graph paper (optional)
Task / There are some children on the bus.
2/6 of the children are wearing tan pants.
6/10 of the children are wearing tennis shoes.
5/12 of the children are wearing a red shirt.
2/3 of the children are wearing a hat.
For each item of clothing, are more than half or less than half of the children wearing that item?
Write a sentence explaining how you know that you are correct.

Limited Performance
·  The student has not shown a clear understanding about how to find equivalent fractions. / Not Yet Proficient
·  Answer is correct, but the explanation is unclear OR work is logically shown but the student has made a calculation error. / Proficient in Performance
·  Solutions: Less than half- tan pants, red shirt. More than half- tennis shoes, hat.
·  The sentence demonstrates a clear understanding of comparing fractions to the benchmark of 1/2.
