LS005: Task chunking and checkpoints

Implementation steps

1. Split final outcome into up to five phases.
2. Define success criteria for each phase.
3. Attach time windows and check-ins.
4. Provide correction at checkpoint boundaries.
5. Adjust chunk size using completion data.
6. Make the final end point visible before phase one so chunking does not hide the purpose of the task.
7. Pre-plan visual and verbal preparation for chunk transitions, especially before independent phases.

Classroom routines

• Display current and next phase.
• Use calm timer cues for transitions.
• Require quality check before phase progression.
• Celebrate phase completion.
• Provide catch-up micro-steps for late starts.
• Coordinate checkpoint language across teams.
• Add a mini-hinge at checkpoint boundaries (whiteboards or one-question checks) so misconceptions are caught early.
• Use a phase checklist card: 'phase 1 done when...' so students can self-monitor without repeated prompts.
• At each checkpoint, require a quick quality check against one criterion before continuing.
• Use a timer plus a brief re-entry cue at each checkpoint so transitions are predictable.
• Give a first-step prompt at each new chunk rather than repeating the whole task.
• Use limited choices at checkpoints when students stall (for example, start with A or B).

Adaptation guidance

• Use smaller chunks in high-anxiety contexts.
• Pair checkpoints with visual exemplars.
• Permit alternative output routes where needed.
• Include regulation breaks between phases.
• Prioritise must-do elements on low-capacity days.
• Use shorter chunk windows and more frequent success points when anxiety or executive load is high.
• Pair chunk boundaries with written or visual copies of the next step when listening load is a barrier.

Staff language prompts

• Finish this phase first, then we check quality.
• You are at checkpoint two; test it against this criterion.
• If phase three feels heavy, start with this micro-step.
• You are only doing phase one now; checkpoint comes next.
• When the timer ends, show me checkpoint one and we will choose the next step.

Impact checks

• Track phase completion rates.
• Compare full-task completion before and after chunking.
• Monitor behaviour incidents in long-task lessons.
• Review quality drift across later phases.
• Track how many students pass checkpoint 1 without adult re-direction (a clear indicator of access).
• Track start latency at each checkpoint boundary, not just at the start of the lesson.
• Monitor how often students re-enter work independently after planned resets.
