Cohort Meeting 3

8:30-3:30

November 20, 2008

Mid-Central Educational Cooperative

Check-In
• Ground Rules
• Introductions
• Lunch (11:30)
Problem-solving Activity
• Use the trapezoid, the triangle, and the blue rhombus from your pattern blocks to complete parts A, B, and C of this question.
• Taken from 3-5 Assessment Sampler

Measurement Concepts with TangramsUsing Nonstandard Units-being able to measure something without a tape measure is a skill that students need to know how to do but struggle with

What is an ANGLE?
• Jot down some ideas on what you believe an angle is
Case Study-14
• What are Angles?
Game: Angle Measurement: Questions to ask Students
• How do you know when one angle is greater than another?
• What benchmark angles can you use to help estimate the size of an angle?
• Do the lengths of the sides of the angles influence which angle is greater?
Case Study-15
• Angles and Turning
This is an angle device that I created
• to represent two rays that have a common end point.
• Walk around with a partner and find different angles and write down what kind of a turn that was made to create an angle
• Page 150-151 Sizing Up Measurement 3-5
Exploratory Activity
• Using the measuring device that was just created, how would I figure out what a quarter, half, three-quarters rotation would measure.
• 360 degrees is what a complete rotation is worth. This is a fact. A piece of information that you just need to tell the students.

Talk about recipe card
