Unit 2

2nd Grade

Unit Summary


In this unit, second graders learn about insects and the impact insects have on the natural world. Building on what students learned in Unit 1 about habitats, they will explore how different insects rely on their habitat for survival. Through this exploration, students will learn the unique characteristics of insects, how insects can be both beneficial and destructive, and the stages of an insect’s life cycle. By the end of the unit, students will have a deeper understanding of and appreciation for the beauty of the insect world.

This unit consists of predominantly shared reading experiences to help students practice different reading strategies and skills. Building on Unit 1, students will continue to be inquisitive, active consumers of texts by asking and answering questions, and they will continue to deepen their understanding of the role text features and illustrations play in helping a reader better understand the content of a text. Students will also begin to explore the connections between scientific ideas and concepts using cause-and-effect language and will continue to strengthen their habits of discussion as they debate and analyze key ideas of the unit.

Essential Questions

  • What impact do insects have on the natural world?

Foundational Skills

Fluency Focus Areas

  • Read with expression and volume to match interpretation of the passage.
  • Use proper intonation to show interpretation of the passage.
  • Reread in order to confirm or self-correct word recognition and understanding.

The main fluency focus of this unit is on reading an informational text with the right expression and intonation to show interpretation of the passage. This includes knowing how to read different text features to highlight the feature's purpose. This also includes rereading and self-correcting in order to figure out the meaning of domain-specific, multisyllabic, or tricky words.

Writing Focus Areas

Sentence-Level Focus Areas

  • Write simple and complex sentences
  • Use frequently occurring conjunctions “because,” “but,” and “so”

As students master complete sentences in Unit 1, we move on to expanding sentences to make them stronger. The focus in this unit is on writing complex sentences using the conjunctions "because," "but," and "so." Including conjunctions in their sentence-level writing not only makes sentences stronger and nuanced, but it encourages students to develop more specific and detailed points.

Paragraph-Level Focus Areas

  • Brainstorm using a Single Paragraph Outline

Students are introduced to the Single Paragraph Outline in this unit as a way to outline their paragraphs before writing. 

Informational Writing Focus Areas

  • Participate in shared research and writing projects 
  • Brainstorm and outline before writing
  • Introduce the topic 
  • Use facts, definitions, and text features to support a point 

Students participate in two shared research projects in this unit; one after learning about insect life cycles, and one at the end of the unit. The focus in both is on crafting strong topic sentences and text features to match their writing.

Speaking and Listening Focus Areas

  • Follow agreed-upon rules for discussions 
  • Build on others' talk in conversations by linking their comments to the remarks of others 
  • Ask and answer questions about what a speaker says in order to clarify comprehension, gather additional information or deepen understanding of a topic or issue. 

In this unit, students transition from focusing on clarifying and sharing their thoughts during a discussion to engaging with the thinking of others. Students learn how to build on others' talk in conversations and to ask questions. The focus areas and discourse in this unit align with Tier 2 of the three tiers of academic discourse and row 2 of the Academic Discourse Rubric (K-2). See the Teacher Tool on Tiers of Academic Discourse to help support students with the focus areas for this unit.
