Unit 3

5th Grade

Unit Summary

In this unit, students explore how plastic pollution is choking the world's oceans. Students first learn about the history of plastic, how plastic ends up in the ocean, how plastic in the ocean impacts the ecosystem, and why it's so hard to remove plastic from the ocean once it's there. Students then explore a variety of solutions for reducing plastic waste and reducing the amount of plastic that ends up in the ocean. Students learn about large policy-based changes that can be made and also explore smaller voluntary actions they can take to make a difference. Finally, students end the unit by doing a research project aimed at educating others about the dangers of plastic and its impact on the environment. 

In this informational unit, students are challenged to explain the relationship between two or more scientific ideas, noticing how authors use description, sequence, or cause-and-effect paragraph structure to help readers notice and explain the connections between events. Students also analyze how authors use a variety of reasons and evidence to support their points, depending on their purpose for writing the text.  

Throughout the unit, students learn how to prepare for class discussions, determining which evidence best supports a particular idea and how to elaborate on that evidence. By writing daily in response to the Target Task question, students build their writing fluency, seeing the power of writing as a tool for understanding what they are reading. Students also set the foundations for strong literary analysis and opinion writing by learning how to craft strong paragraphs and multiple-paragraph essays.

Please Note: In October 2025, this unit and its lesson plans received a round of enhancements. This unit is now 27 instructional days (previously 25 days). Teachers should pay close attention as they intellectually prepare to account for the updated pacing, sequencing, and content.

Assessment

The following assessments accompany Unit 3.

Content Assessment

The Content Assessment pushes students to synthesize unit content knowledge or unit essential questions in writing. The Content Assessment should be used as the primary assessment because it shows mastery of unit content knowledge and standards.

Cold Read Assessment

The Cold Read Assessment tests students' ability to comprehend a "cold" or unfamiliar passage and answer standards-based questions. The Cold Read Assessment can be given in addition to the Content Assessment as a pulse point for what students can read and analyze independently, a skill often required for standardized testing.

Fluency Assessment

The Fluency Assessment allows teachers to monitor students' oral reading fluency progress with a reading passage drawn from one of the unit's core texts. Find guidance for using this assessment and supporting reading fluency in Teacher Tools.
