Presentation Transcript

### Purpose:

• Learn about a framework for thinking about geometry tasks (to keep in mind as teachers talk about using problems in the classroom)
• Try out an activity that teachers will do in FGT Session 9 to learn about this framework

### Flow:

• Brief intro to framework
• Apply framework to geometry tasks
• Discuss framework as a full group
• The use of this framework in FGT

Tasks as they appear in materials

Tasks as set up by teachers

Tasks as carried out by students

Student Learning

Memorization

Procedures without Connections

Procedures with Connections

Doing mathematics

Memorization:

How many degrees in a circle?

Procedures without Connections:

What is the area of a circle with a radius of 4 inches?

Procedures with Connections:

Question 1 from Finding Centers of Rotation (trace path of point with string and say what you notice)

Doing mathematics:

Where is the center of rotation for these two segments?

• Work through the six tasks and categorize them according to the Geometric Task Demand Framework. (until 2:25 minutes)
• Discuss how you categorized the six tasks with your partner. Describe why you think the tasks fit with particular parts of the framework, especially in cases where you and your partner disagree. (2:25-2:35 with Fostering Geometric Thinking partner #9)
How does this fit into FGT?
• Teachers will use this task sorting activity to learn about the Geometric Task Demand Framework in Session 9.
• Teachers will then be asked to consider the Framework in later sessions as they prepare to use FGT problems with students to capture thinking.
