What perspective and assumptions do you bring to your teaching? In this episode, Pam and Kim discuss the kinds of teachers they've interacted with and their own growth as teachers.

Talking Points:

• "Inquiry-based" + Mimicking
• "Direct teach" + Mimicking
• "Inquiry-based"+ Math-ing
• "Direct teach" + Math-ing

What can we do to keep students thinking, instead of waiting to be told what to do? In this episode Pam and Kim focus on an algebra Problem String that helps students learn to choose between strategies.

Talking Points:

• What it mean to keep kids in "Thinking Land"
• How to keep students actively reasoning versus cueing them to mimic/memorize steps
• How the same instructional phrase can lead students into or out of "Thinking Land"
• Ask yourself: "Is this direct move keeping kids reasoning, or just cueing mimicry?"

What does explicit teaching mean to you? In this episode, Pam and Kim discuss an Adding Mixed Numbers Problem String, idenitfying exactly what teachers should be explicit about versus what they should leave for students to grapple with.

Talking Points:

• Being explicit about the student's job during a Problem String
• Ways to nudge students to make connections
• Eliciting specific strategies
• Creating helper problems

When do we allow students more freedom, and when do we need to be more explicit? In this episode, Pam and Kim analyze a Distance vs. Removal subtraction Problem String, identifying when they are explicit and when they are not.

Talking Points:

• Intentional contexts, number choices, and problem order
• Choosing which strategies to elicit and represent
• Planned board layouts 
• Focusing the conversation 
• Highlighting mathematical behaviors
• Layering explicit content, behavior, and community goals around open-ended student reasoning

Many aspects of teaching can be improved by being more explicit. In this episode, Pam and Kim identify specific categories where explicit teaching is necessary, borrowing Piaget's distinction between social-conventional and logical-mathematical knowledge.

Talking Points:

• Being explicit about a goal doesn't mean teaching it as a step-by-step procedure.
• Good teaching requires explicit goals.
• Examples of Math Content Goals 
• Examples of Math Behavior Goals 
• Examples of Community Behavior Goals
