Reflection: Developing a Conceptual Understanding Geometric Drawings - Section 2: Explore

 

I definitely see value in having the students grapple with the constructions.  I had some students get a bit of an attitude because I was very vague regarding whether the construction could be done or not - and students did not like the ambiguity.  However, once they realized I was really not going to help them they started helping eachother and comparing their figures - and it made it so much easier to fill in the rules at the bottom of the notes sheet.
