I'm sorry that I am not her on our first constructed drawing day. You should still be able to start via videos. There are 2 rules that must be followed ALWAYS
1) You my only draw a line or an arc with a compass or a ruler. NO freehand drawing.
2) You may only draw a line that connects two points of intersection. No drawing a line because you think it looks right.
These drawings are graded at the beginning of following days class, so you are turning these in and they do count.
10 points- best in class
9.5 points- correctly constructed with additional constructions
8.5 points- correctly constructed and colored nicely with the use of a rule on the edges
7.5 points- correctly constructed not colored (exactly like the example)
6.5 points- not correctly constructed
Your first drawing is of a cube with a corner taken out. The example is in the top left corner of the video.
Here are the how to videos. You are going to have to pause the video as the students follow the instructions. Try not to move to the next step until everyone has successfully gotten their drawing to look like the one on the screen.
cd cube part 1
cd cube part 2
This is how the drawing go. We find one hidden line together an the rest is up to you to figure out. Once your drawing is completed, feel free to get your markers from your locker to color. You can also add a smalled cube inside the missing corner for the 9.5.
