Teaching Table

Set out your lesson

Describe four shape-changing actions while noticing material limits.

Activity

Follow this model in an accessible mode before attempting independent work. Graph ordering is not learner mastery; revisit prerequisites if the guided task still needs full modeling.

Policy

Check readiness rather than assuming source graph order establishes attainment.

Optional soft modelling dough, cloth and sponge; no wire ends, snapping wood, strong elastic or small choking pieces. Adult checks materials. If absent, discuss the supplied cases. Open Show (S), then Guided (G), then Try (T). Hide earlier work and keys before Try. Use only the supplied stage material; do not invent additional cards. Pause or split the session if needed.

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.

partial: Investigate how the shapes of solid objects can be changed by squashing, bending, twisting, and stretching
Four physical demonstrations remain conditional; discussion cannot substitute for observed handling.
partial: Demonstrate four ways to change the shape of a solid: squashing, bending, twisting, stretching
Four physical demonstrations remain conditional; discussion cannot substitute for observed handling.
partial: Compare how different materials respond to these forces (e.g. clay squashes easily, wood does not)
Four physical demonstrations remain conditional; discussion cannot substitute for observed handling.
partial: Explain that the material itself stays the same even when the shape changes

partial: Can {{name}} show you how to change the shape of clay by squashing it, twist a pipe cleaner, and explain that some materials bend while others snap?
