### Understanding Student Thinking in Geometry and Measurement

January 30-31, 2012

Goals
• Geometry
• What is and angle?
• Attributes and Definitions
• Minimal Defining List
• Measurement
• The value of estimation in measurement
• Structuring Area
• Measurement concepts with Tangrams
• Angle Measurement
• Aspects of size
• Moving from informal to formal
Exit Question Activity from October
• Partner up with your elbow partner and discuss for 5 minutes.
What is an Angle?
• Watch video “What is An Angle”
• Share out student definitions
Making Polygons
• Make polygons that satisfy each set of conditions on your worksheet.
• Make triangles
• Make hexagons
Definitions versus Attributes
• What is the difference between an attribute and a definition?
• Minimal Defining List page 230 in Grade 3-5 Van de Walle
Measurement
• Read Van de Walle Measurement Introduction
• K-3 Book: Chapter 8 pgs. 223-228
• 3-5 Book: Chapter 9 pgs. 252-257
• Note big ideas while reading
Go-Around One Protocol
• Person #1 reports one idea that she/he recorded
• While Person #1 reports, other group members listen, but do not question Person#1, comment, or give clues.
• When Person #1 finishes, Person #2 reports while the group listens.
• Repeat until all group members have reported all of their ideas.
• The group discusses ideas that were reported.
Dismiss

See you back here at 8:00 tomorrow morning!!!!

String Activity
• Discuss in small groups:
• What was the purpose of this activity?
• What did we learn about our students?
• In small groups review student work and score their work and compare the scoring that was done.
• How would this activity help students make sense of area?
Measurement Concepts with Tangrams
• Work on handout with small group
• What are the mathematical concepts being developed?
• How would this activity help students make sense of area?
Triangle Areas
• Make as many different triangles with 6 square units on your 10 x 10 dot grid paper.
• If you were not restricted to the 10 x 10 grid, what is the largest perimeter possible?
Angle Measurement Activity
• Look at the two angles. Which angle is larger?
• What is an angle?
• What does it mean for a triangle to have 180˚?
• What does it mean for a four sided figure to have 360 ̊ ?
• What does it mean to say a line has 180 ̊ ?
• What does it mean to say a circle has 360 ̊ ?
• What is the purpose of this activity?
Amelia Earhart Problem
• Read through the problem and work independently.
• Discuss with shoulder buddy.
