I finally finished making the Constructive Triangles and am thrilled with the results! It was very easy to do and really looks great! All I did was buy the appropriate color fun foam. (I substituted the gray for purple) I printed off the constructive triangle patterns and blue triangles (black and white versions only) from http://www.jmjpublishing.com/sensorial.htm. Then I roughly cut them out and taped them to the foam. I took my time and carefully cut out the foam. I finished by using a sharpie to add the blackline to the edge for matching. I chose to store ours in zipper bags for now, I also cut out a small control of error to toss in the bag. (more for me than Josh!) I plan to present these this week using these lesson plans. So...what have you made lately? Shannon
