Watch: Combine repeated durations, normalize to the declared unit, and enter the exact total duration. The shell keeps the complete question visible, reserves the canonical reply band, and reveals proof on the same task objects.

Misread: Child action: Combine repeated durations, normalize to the declared unit, and enter the exact total duration.

Curriculum: Mapped to Capacity and liquid measure.

Read a liquid level, gauge, or marked container to determine capacity or volume in a story-relevant measurement context.

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.

ActionUse 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.
CheckComplete the measurement conversion table entry action.

Rate or money operation-and-rounding entry

Rate or money operation-and-rounding entry asks the player to compute the requested rate, money, time, or other declared unit-bearing amount using the task's explicit operation order and rounding policy, then enter the permitted numeric response with its declared unit.

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

  • Episodes whose mathematical action is convert unlike measured quantities into one declared unit and combine them exactly.
  • Contexts that preserve the canonical mathematical action without changing the response or answer rule.
