Teaching Table

Set out your lesson

Track the same pieces through disassembly and a new arrangement.

Activity

Can attend to a short explanation and respond orally, by pointing, drawing or writing; check relevant prerequisite understanding rather than assuming age proves readiness.

Policy

Check readiness rather than assuming age or source graph order establishes attainment.

Materials

Prepared passage, diagram materials are available in each step.

Preparation

Open the teaching material first. Keep the adult key and check sheet separate until their named stage. No printing, purchase or external media is required for the supplied adapted text tasks.

Safety

Optional large age-appropriate blocks only; no small choking parts or disassembly of appliances.

Optional Observation

Only record a real observation after the activity is actually carried out safely; otherwise mark not carried out.

Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.

What this lesson covers and its limits

These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
