1. Common Core High School Mathematics: Transforming Instructional Practice for a New Era 1.1

2. Learning Intentions & Success Criteria Learning Intentions: We are learning to deepen our understanding of the Common Core State Standards and the implications for teaching and learning mathematics. Success Criteria: We will be successful when we can describe how the content standards and math practice standards are evident in the implementation of a mathematical task. 8.2

3. Agenda Homework review and discussion Slicing a cube Reading G-GMD and G-MG Break MKT assessment Reflection and goal setting Tying up loose ends 1.3

4. 1.4 Homework Review and Discussion Activity 1: Table Discussion: Discuss your write up for the day 8 math task Tangent line and radius: Compare your strategies with others at your table. Reflect on how you might revise your own solution and/or presentation.

5. 1.5 Slicing a Cube Let’s begin with a warm-up: What figures can be produced when a plane slices through a sphere? As a table group, discuss the possibilities. Try to come up with a complete list. (How do you know that your list is complete?) Activity 2:

6. 1.6 Slicing a Cube Now for the real question: What figures can be produced when a plane slices through a cube? Try to visualize possible answers to this question individually. Compare your understanding with your table group. Do you find this question easier or harder than the previous one? (Why?) Activity 2:

7. 1.7 Slicing a Cube At your tables, consider the list of figures on the handout. Which do you think are possible to obtain, and which are impossible, when a plane slices through a cube? Begin by experimenting with the plastic cubes and the colored water, but eventually you should provide geometric reasons to support each of your experimental conjectures. Activity 2:

8. 1.8 Reading G-GMD and G-MG Read these standards from the high school Geometry conceptual category Turn and talk: How do you see these standards in the activity you have just completed? Activity 3:
