Going into Geometry, I knew there were a bunch of manipulatives necessary, but did not realize the extent. Since I feel like I have to supply most of them, this has been a challenge. I do remember the challenges of using a protractor during the old Math A days. However, students did not have to be proficient in using it. Now, they need to know it to get through all of the different types of proofs and postulates of triangles. I think they will realize it is a necessity to gain the skill to prevent being annoyed with themselves. At least, I hope that is the case. If I remember, I will comment on this later.
Once the students tooled around bit with the protractor measuring angles of a triangle, we set out to prove the angle sum property. This is the first proof that we are doing as a class and all of them are struggling. I had all of them be quiet for 10 minutes studying the materials and then had a bunch of discussions at the table and as a class to get them further. Tomorrow will be a continuation of the journey into the proof.
