Angle Relationships

We just had a fantastic workshop for the third nine week SOLs but we also focused on previous SOLs that were troublesome, angle relationships being one of them. A collegue presented "Can You Build It?," a great activity where students use pipe cleaners to build an angle using a protractor and then add to it its complement or supplement or making it part of a vertical pair. I'm looking forward to using it as a re-teaching tool. I'll let you know how it goes.
