Background For Teachers:
Ways to Gain/Maintain Attention (Primacy):
Starter: How great is your memory from your past experiences Contest? Try to match each word to the correct picture.
Lesson Segment 1: Where are examples of lines, segments and rays, parallel
and perpendicular lines and midpoints found in the real-world? found in the
real-world? How does midpoint differ from other points on a line?
Lesson Segment 2: Where are examples of angles found or used in the realworld?
Lesson Segment 3: How can I describe attributes of angles?
Classifying Angles Song
Iím a little angle. I like me like that.
ím a RIGHT angle, and I look square.
Iím rather large, so I have pride.
Have students use Two-color Circular manipulative to show attributes such as acute, obtuse and right as you ask them to. (A two-color manipulative can easily be made to allow the students to demonstrate angles. Make a cut in two different colored small plastic plates from the circumference to the center of the plate. Slide the two plates together at the cut.)
Have students re-sort the angles into acute, right and obtuse categories (if they did not originally do so) and write the category on the back of the card.
Lesson Segment 4: What is the measure for a given angle?
Using the Two-Color Circular manipulative again, call out angle degrees and have the students rotate the sections of their plate to show an estimate for the measure.
Students will enjoy practicing angles measures using a virtual protractor by going to this site: http://www.kidport.com/Grade6/Math/MeasureGeo/MeasuringAngles.htm
Assessment: Have students complete the quiz attached
