Geometry - Protractors

Before a child uses regular protractors in the elementary Montessori environment, the Montessori protractor is introduced. It is used to show the 360 degrees of the circle and its parts (fractions). We show the children how to measure other angles that are not parts of circles, and this learning is extended into measuring any kind of angle with a regular protractor. Yes, there is an album page at elementary called "Regular Protractor." :)


  1. Ha! You totally just cleared up something I have been wondering about. Thank you!

  2. Wonderful to hear that it was helpful :)

    Do let me know if there is anything else I can clarify - I'm always looking for ideas on here, my other Montessori blog, and anything that needs clarification in the elementary albums I offer :)
