Teach it step by step
- Ask what the learner already knows. Introduce the objective and read the explanation together.
- Work through the example aloud. Pause for the learner to explain why each step or piece of evidence matters.
- Choose a video if useful, then connect it to the example. Let the learner complete the independent practice before checking the explained answers.
- Discuss the question below and finish with the exit check. Revisit the example if the reasoning is unclear.

Understand the idea
A topic names the subject. A central idea states what a text develops about that subject. Supporting evidence must be relevant to that idea; a fact can be interesting without supporting the claim you are making. A summary keeps the main ideas and essential details, while leaving out personal opinions and minor examples.
Worked example
Read this original passage: “The school replaced several empty paved areas with garden beds. Students recorded insects visiting the flowers. Science classes compared soil moisture in shaded and sunny beds. The garden became a place for observing living systems.” The topic is a school garden. A central idea is that the garden created opportunities for scientific observation. The insect records and moisture comparisons directly support that idea.
Try it yourself
- Name two details that support the central idea in the passage.
- Would “The garden made lunches cheaper” be a supported central idea? Why?
- Write a one-sentence summary without adding an opinion.
Check your reasoning
- Students recorded visiting insects and compared soil moisture. Explain that both activities gather evidence about living systems.
- No. The passage gives no information about food costs or lunches.
- Possible summary: A new school garden gave students places to observe insects and investigate soil moisture.
Make it work for your learner
For support, model the example one step at a time and ask the learner to explain each choice in their own words. Use a sketch, organizer or physical model where helpful. For a challenge, create a new example, test an alternative explanation or describe when the model would not apply.
Exit check
State a central idea and explain how specific details support it. Explain your reasoning with a specific example before moving on.

Use evidence in a conversation
Discussion question: Which detail supports your central idea, and which detail would not? Give an objective summary.
- Before discussing, write a tentative answer with two details from the lesson’s passage, example or data. For a longer discussion, the teacher can add an age-appropriate source.
- In pairs, a group or a tutor–learner conversation, agree on roles: facilitator, evidence finder and note taker. Combine roles when needed and allow equal time to respond.
- Share evidence, ask a clarifying question and respond to a different interpretation. Explain which details support or challenge a claim.
- Paraphrase another person’s point. Write a final conclusion explaining what changed, what remains uncertain and what evidence you would seek next.
Teacher look-for: Accurate use of the example, reasons linked to evidence, thoughtful questions and a response to another viewpoint. A well-supported alternative answer is welcome.
