Did you know that students can understand negative exponents without being told what they mean? In this episode Pam and Kim wrap up their series on exponent relationships.
Talking Points:

• New listeners, where to start? Episode 156 Start Here
• Discovering Negative Exponents
• Give students experiences first and let them make sense of it
• Using equivalent expressions to help students visualize and make generalizations
• What grade levels are these strings for?

What if students actually understood using common factors to simplify complex division expressions? In this episode Pam and Kim divide exponents without reciting a rule.
Talking Points:

• Thinking versus reasoning
• Problem String Dividing Exponents
• "Canceling" vs "Dividing out to equal 1"
• Focus on left over factors vs mimicking a rule
• Why start with smaller bases?

When variables and exponents start mixing, we need to memorize the rules, right? In this episode Pam and Kim develop exponential relationships, not rules.
Talking Points:

• How "Kim's Notes" became "Half Sheets"
• Problem String to explore multiplicative relationships when working with exponents.
• Generalizing multiplication of exponents

Would you believe I'm more comfortable dealing with exponents because I haven't memorized the rules? In this episode Pam and Kim continue building exponentiation with a great problem string
Talking Points:

• Problem string to help build exponentiation
• When and how to introduce vocabulary
• Teacher move: Choosing who shares, and in what order
• More confident reasoning without the rules
• Teacher Move: Generalizing

Can we prepare students for really hairy exponent problems without resorting to memorized rules? In this first episode of a series, Pam and Kim share a task that could get kids and teachers thinking more and more multiplicatively and understandably about exponents.
Talking Points:

• Can a task have too many layers for students to be successful?
• Can we sequence a task that works for 3rd grade to Algebra?
• Problem String to connect prime factorization to exponents.
