Students have more practice using a protractor to measure angles in triangles. They learn how to extend a triangle's sides in the case that the triangle is smaller than the protractor
A. Explore degrees
B. Measure and represent angles using degrees
C. Explore protractors
D. Identify the parts of a protractor
E. Measure angles with a 1-scale protractor (Level 1)
F. Measure angles with a 1-scale protractor (Level 2)
G. Measure angles with a 2-scale protractor (Level 1)
H. Measure angles with a 2-scale protractor (Level 2)
I. Measure angles with a 2-scale protractor (Level 3)
J. Correctly align a protractor to measure angles
K. Measure all the angles of a triangle
L. Measure angles in triangles (Level 1)
N. Identify 180 degree angles
O. Measure 90 and 180 degree angles using a protractor
P. Use protractors to draw angles
Q. Use protractors to draw acute and obtuse angles
