What’s included

5 student pages with a worked example and four original readings
8 open responses with space for main ideas and evidence
Separate 8-page teacher guide with all keys, alternatives, supports and next steps

Practice explaining a main idea with evidence from both paragraphs. This set includes four original short readings about tide pools, maps, beaver ponds and moonlight, plus an explicitly imagined shared-tool example. Eight open responses ask learners to state or improve a main idea and explain how details support it.

The set is intended for grades 3–5 learners who can follow a short two-paragraph informational text, locate explicit facts, distinguish a topic from a sentence and explain a connection with vocabulary support. Each reading and its response boxes share one sheet. The five student pages and separate eight-page teacher guide are provided as two PDFs.

How to use it

Model the difference between a topic, a narrow idea and a supported main idea using the Find the main idea from details reference sheet.
Guide the tide-pool and map readings, then use the beaver reading for independent synthesis.
Keep Moonlight in the sky for a later check. Collect the main idea, explanation of the claim and supporting details before discussing answers.

Teacher support

The companion includes complete keys with criteria and alternatives, misconception-specific feedback, vocabulary help, access options and next steps. Different wording is welcome when it accurately covers both paragraphs and the detail links make sense.

Use vocabulary clarification, read-aloud access or oral rehearsal as needed. A scribe or AAC can preserve the same explanation goal. The guide distinguishes this focused main-idea practice from full summarizing or comprehensive standards mastery.

Students will

State a main idea that covers both paragraphs of a short informational text
Explain how one accurate detail from each paragraph supports the main idea
Revise a narrow or unsupported main-idea statement
