Changes in the current files · 2 November 2026
- The teacher guide includes annotated fictional sound, partial and error responses, with concrete teaching actions and evidence to seek next.
- Browser printing keeps task prompts with their response space; the underlying tasks retain their stated editions.
Compare new evidence with a particular claim, check conditions and justify retaining, narrowing, changing or withholding a conclusion.
Prepare the materials
Prepare this lesson or activity
Recommended selection edition 1.0.0. Original source files retain their displayed editions.
Use the matching guide to choose a response to the work you observe. Clarify access and task wording first; one response is not a diagnosis. Keep independent work, later tasks and answers aside until their intended use.
Current teacher guidance: 2 November 2026. Student tasks retain their stated core edition; use the matching current guide linked here. Earlier files are kept separately in the archive.
- Audience / fit
- Intended Grade 6 science; selected Grades 6–8 standards ideas
- Teaching or planning target
- Compare new evidence with a particular claim, check conditions and justify retaining, narrowing, changing or withholding a conclusion.
- Essential prerequisites
- Read starts/changes and compare trials and conditions. The included prerequisite mini-lesson teaches claim scope and revision choices; the kit works independently of earlier kits.
- Preparation
- Read the supplied teacher quick start; preparation time depends on the selected route.
- Use time
- Allow about 45–55-minute full lesson or split over two lessons; 15–20-minute reteach; 10–15-minute later check. Planning estimate; adjust for your class.
- Materials
- Paper and pencil only. Optional calculator, number line, projection, pointing, labeled representation or oral response. No practical experiment required.
- What to print
- Print the chosen activity. Follow the source or reveal instructions beside it.
Evidence to notice: Look for a claim and its support before the new record, then an explained decision to retain, narrow, change or withhold the claim. A newer record does not by itself require a change.

Current print and editable package
Library package prepared 2 November 2026. Revised guides are marked with that date; other files retain their stated editions. Keep this package with the teacher. Read START-HERE, choose one stage, and retain teacher keys and checks for later use in their separate folders. Online browser versions are linked from the preparation pages.
Choose from the response
Choose the next teaching move
Describe what the learner said, wrote or showed. Check access, wording, prerequisites and calculation before interpreting it. A single response is not a diagnosis. Record support and prior exposure; a helped or rehearsed task is practice.
For every initial/new pair, give the initial page and retain its response before revealing the new page. Teach the prerequisite bridge in the matching guide first. Keep later evidence and all answers with the teacher; the older Quick Check repeats the independent pair.

For each pair, give the initial evidence, have students write and retain their original claim, then reveal its matching new evidence. Model → guided practice → independent check are distinct pairs. The model’s blank revision record accompanies the new model evidence. Keep all reteach, fresh recheck and later-assessment pairs separate. The original Quick Check repeats the independent pair.

About the materials
The teacher guide includes complete keys, explanations, alternatives and guidance for choosing a next task.
Accept scientifically adequate labeled representations, oral explanations pointing to data or connected prose. Clarify unclear responses before choosing a reteach. A rigid paragraph format is not the target.
