Below please find three types of protractors. In my experience, it is easier for students to use the last one because all 180 degrees are marked, the baseline is clear, and every 10 degrees there is a straight line that runs to the centre of the protractor which assists with reading accuracy. If possible, please send that type with your child. Thank you in advance!
degrees missing - only every 15 degrees are marked |
empty centre area - nothing to assist with measuring |
has all of the features to assist students |
