Task formats

Measurement conversion table entry

Measurement conversion table entry asks the player to use a declared exact unit-conversion relation to determine exactly one missing target measurement in an equivalence table and enter the exact magnitude through one separate target-unit-owned field.

Selection

Fresh independent work can move toward Core, Transfer, or Challenge routes; help use or confusion keeps support visible.

Help

Hints keep attention on the visible structure; reveals show the path without counting as independent evidence.

Presentation

Presentation can reduce reading and interaction load without changing the selected skill. Practice focus can bias compatible work without breaking prerequisites or story fit.

Story fit

  • Contexts that preserve the canonical mathematical action without changing the response or answer rule.
