Thanks to all of you who joined us this morning! We had fun, as aways :) Brian spent about 30 minutes talking us through bisecting a line, and then creating this beautiful construction. The main lesson page below is an example of one you could make with your students, whether in the classroom or at home. The link to the replay is here. It will be free for 3 days (until Monday 2/15/16)!
**Note on some of the terms we used..... yes, a straight-edge IS a ruler....unless you're Brian, and then it's a straight-edge ;) I think his thinking is that you could really use anything for that tool (the side of a book, for example)...it doesn't necessarily have to be a ruler. Also, YES! White-out IS liquid paper, for all our Canadian/Aussie/European friends!
