Do we flip the sign when its negative? Or is it we keep the sign and flip the minus? I'm confused! In this episode Pam and Kim avoid all that confusion and make solving inequalities figureoutable!
Talking Points:

• Open Number Lines for Inequalities
• Using "Reflecting the inequality" vs "flipping the sign"
• Reasoning about balancing the equation

Do we need to memorize a bunch of rules to solve linear equations or can we reason about them? In this episode Pam and Kim use a model to make thinking visible and keep students reasoning! 

Talking Points: 

• Modeling on a double open number line
• Finding where x lies on a double open number line.
• Grappling with the opposite of x 
• Building integer sense as well as building equation solving sense
• Reasoning about an equation versus balancing an equation
