# Concept-Checking Questions (CCQs) and Timelines

CCQs check that learners understand the meaning, not that they can repeat the form. Rules:

1. Break the concept into its parts and ask one question per part.
2. Use simple language below the level of the target item.
3. Do not include the target language in the question.
4. Answers are yes/no, a short phrase, or a choice ("now or in the past?").
5. Never "Do you understand?" - learners say yes whatever they understand.

Model sentence first, then the CCQs with expected answers.
