# Parallel and Perpendicular Lines Foldable

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.

Parallel lines IN THE SAME PLANE never intersect.

Great foldable !

Love your blog!

Thanks for the clarification and your kind words! I was definitely only thinking in algebra mode when making this…

Obviously if students are going to use colorful paper and makers, one would assume we are only observing a single plane.

I used this today in my Algebra 1 class. The kids were really into it.

Thanks for sharing!

Modifying this down for my 5th graders! Thanks for the idea 🙂

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

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 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!

I love reading comments like this!

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!

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!!

Thanks for sharing!!!

Thank you! I am a stickler on graphing so thanks for the printed graphs!

Oooh, we're using this today!!!! Thank you for making this so I don't have to write out twenty copies!!!
