Teaching Table
Set out your lesson
Classify whales and dolphins as mammals using evidence rather than habitat.
Can attend to a short explanation and respond orally, by pointing, drawing or writing; check relevant prerequisite understanding rather than assuming age proves readiness.
Check readiness rather than assuming age or source graph order establishes attainment.
Prepared passage, worksheet materials are available in each step.
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.
Use the supplied text/schematic indoors. Do not collect, taste, touch or disturb wildlife or unknown materials. Discussion does not require a personal experience.
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.
- partial: Know that whales and dolphins are mammals, not fish — they breathe air, are warm-blooded, and feed their babies milk — even though they live in the ocean
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: State that whales and dolphins are mammals, not fish
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: Give at least two reasons why: they breathe air and feed babies milk
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: Explain that living in water does not make an animal a fish
Bounded task opportunity only; this task samples the clause using recall evidence, not full coverage or learner attainment.
- partial: If {{name}} saw a dolphin jumping out of the water, could they explain that dolphins are mammals like us — they breathe air and feed their babies milk — not fish?
