Right Angles & Turns
Identify right angles; recognise that two right angles make a half-turn, three make three-quarters, and four make a complete turn

Teaching Table
Set out your lesson
Use a square corner and quarter-turns to compare angles.
Inferred, not a taxonomy edge: learner can access the supplied prompt with agreed support and can explain or mark a response. If earlier skills are unfamiliar, use the prerequisite topic for teaching; an authored prerequisite is not proof this learner is ready.
Keep the two adult-only cards off the learner screen. Have a pencil and scrap paper if useful; oral pointing/typing/AAC can replace handwriting unless spelling or composition is the target. No printing, cutting, account or purchase is required.
Open Show first, read the explanation together, and pause to check the central idea. Then do Guided Try together.
For Try, close earlier models and the adult keys unless the task explicitly supplies a reference. Record any hints, read-aloud help or model reopening; do not call supported work independent.
Use only the active learner card. Keep the private key closed until an attempt is recorded. Stop or take a break on request; practical claims stay not observed unless actually done.
Use on screen; read aloud or recreate a tactile model only with declared support. No printer or purchased kit.
Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.
Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
Geometric comparison and tabletop turns, not mandatory physical movement or all environmental right angles.
These bounded examples do not establish independent performance in other situations. Record the support used.
Never display adult keys or dictation spellings with a learner task; no family financial, identity or conflict disclosure.

Check understanding
- Use a right-angle checker to identify right angles in shapes and the environment
- Classify angles as right angles, less than a right angle, or greater than a right angle
- Explain that 4 right angles make a full turn (360°)
“If your child looks at the corner of a piece of paper, can they tell you that's a right angle — and that spinning all the way round takes four right angles?”
