Let's Reflect
How might we help students develop their Mathematical Practices? How might we:
  • develop questioning techniques that use students' responses to help inform the next steps of classroom instruction?
  • maximize each student's "talk time" by using pairs and groups and targeted tasks?
  • make the most of student accountability by encouraging students to engage in viable arguments and discuss their reasoning with others?
