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
What is an ANGLE?
  • Jot down some ideas on what you believe an angle is
case study 14
Case Study-14
  • What are Angles?
game angle measurement questions to ask students
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
Case Study-15
  • Angles and Turning
this is an angle device that i created
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
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.
