# Parallel and Perpendicular Lines Foldable

Post Contents

Today, I want to share a parallel and perpendicular lines foldable I used to introduce the concepts of these different types of lines to my Algebra 1 classes.

Quote of the Day: “I’m going to name my kid ‘Perpendicular.'”

I’m not the biggest fan of what I had my students write inside the foldable.  It was a little wordy, and I will tell you that the amount of writing decreased with each class period that I taught this.  I put this together at the last minute, and it shows.  Next time I cover this topic, I will revisit this and revise.  Any advice would be greatly appreciated!

The following year’s foldable for this same topic was almost identical.

Thanks so much for the great foldable! I am picky, and wanted to have graph paper and cut down on the amount of writing my kids had to do, so I created the following version of your foldable in a google doc! I figured I should share it back with you! Thanks again!!

I altered the foldable a little bit I left out Neither and after we defined Parallel and Perpendicular I gave an example and we pasted graph paper into the foldable and graphed the examples. I also had this open up and down instead of left to right (I hope that makes sense).

Thanks for sharing! Graph paper is an AWESOME addition!

I used this today in my class and it definitely helped for my ELLs! After I showed one example, I had the kids draw their own examples, which definitely helped clear up some confusion on perpendicular vs. intersecting. One girl even drew two lines that didn't intersect on her page but used arrows to show that they would eventually intersect. Awesome math conversation!

Thanks so much for your stuff, I always love it!

Instead of "neither", I would use the word "intersecting". Thanks for the idea :)

Ooooh! What if you had two flaps: Parallel and Intersecting? Then, you opened the Intersecting flap to reveal two more flaps: Perpendicular and Intersecting but not Perpendicular. You have given me an idea! Thanks!

I would modify this to use the space on the flap for example equations of each type. Love this, thanks for the idea!
