Instructional stance

Begin with measurement meaning: capacity, container size, and a sensible unit. Then organize the unit relationships. A mnemonic is valuable only when learners can use it to reason.

Suggested grade bands are practical guidance, not claims of formal standards alignment. Adjust numbers, language, and pacing for the learners in front of you.
