I started a new unit in Geometry- Parallel and Perpendicular Lines. I started with a card sort. I numbered the back of the page going across 1-12. Then I copied each page on a different color of card stock and cut those in half. I passed it out to the students and had them cut out the individual squares. (Yay for student labor!) Unfortunately, when they cut, the numbers were cut in half which posed some problems. Maybe you should have students number them after they cut? Not sure what happened on my end.

This is awesome! It seems like everything you share this year is exactly what I am doing at that very moment. Since we are starting parallel and perpendicular on Monday in Algebra I, I was just thinking last night that I needed to get an activity together. This will not only help their understanding of parallel, but will also allow them to practice their solving for y skills.

ReplyDeleteYees, solving for y was my main goal for that lesson but parallel just fit so nicely! I heard at a conference that students usually mix up parallel and perpendicular because we teach them on the same day so I decided to split them up. Here's what I made for perpendicular if you want it: https://www.box.com/s/yub03txc98yd8viwof4f

Deletethanks Elissa this is awesome. I'm stealing for the lines unit I'm starting as soon as we return after the hurricane. My geometry kids have to pass a new Algebra state test this year so anything that reinforces algebra is great for me- and them

I find that students usually like the algebraic parts of Geometry just because it is something familiar.
