Core Components with a brief description of specific adult actions (The teacher will…)
Build on Student Thinking: Advance student understanding by asking questions that build on, but do not take over or funnel, student thinking.
Seek Explanation and Justification: Ask questions that go beyond gathering information to probing thinking and requiring explanation and justification.
