Teaching Table
Set out your lesson
Sort shapes with a rule that actually fits each member.
Ask the learner to explain one prerequisite idea before starting. If uncertain, revisit it; graph order is not learner readiness.
Check readiness rather than assuming source graph order establishes attainment.
Use supplied shape-property cards and optional safe box/ball. This is supported property sorting, not picture recognition.
Use the supplied stage cards on screen or scrap paper; adult key stays separate.
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: Compare and sort common 2-D and 3-D shapes and everyday objects by their properties
Bounded objective: Sort shapes with a rule that actually fits each member. Text properties supplied; visual recognition and handling real solids are not established by this sort.
- partial: Sort a collection of 2-D shapes by number of sides
Side-count grouping uses supplied properties, not unaided shape recognition.
- partial: Sort 3-D shapes by number of faces or whether faces are flat/curved
Flat versus curved surface sorts use declared face convention.
- partial: Explain criteria used to sort a group of shapes
Learner states and tests rule on new supplied-property cards.
- partial: Can {{name}} sort a collection of shapes into groups — for example, separating all the shapes with curved sides from those with only straight sides?
Try offers supported-new-card-sort for the bounded objective; it does not establish every part of the source assessment. Text properties supplied; visual recognition and handling real solids are not established by this sort.
Text properties supplied; visual recognition and handling real solids are not established by this sort.
