Teaching Table
Set out your lesson
Make a mathematical explanation checkable, including finding an error.
Comfort with the particular task and communication mode; optional oral/scribed work is recorded separately.
Check the learner can access these words/materials and prerequisite ideas; historical authorship is not readiness or mastery. If not, demonstrate briefly or revisit the named prerequisite.
Use drawings or counters if useful. Adult asks ‘How does that step follow?’ without supplying the answer. No printer: view only the active learner card on screen, or an adult copies its exact prompts onto plain paper without answers. Oral pointing/dictation is an access option; record it as adapted/supported and do not claim handwriting from it. Keep adult keys/scripts separate; supply only the current stage.
Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.
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.
Prompted explanation matches the contract; not evidence of independent proof across mathematics.
Use fictional cases and invented identifiers; never record personal conflicts, health, bank details or family spending. Adult prompts/keys are private companion files, never learner links.

Check understanding
- Explain a solution strategy using a drawing or number sentence (e.g. 'I made ten first, then added the rest')
- Justify why an answer is correct by showing an alternative method that gives the same result
- Identify and explain an error in a worked example or a peer's solution
“If you ask your child "how did you work that out?", can they show you with a drawing or explain their steps in simple words?”
