Pythagorean Theorem INB Pages

I had fun teaching the Pythagorean Theorem this year!  My students still didn't love having to simplify the radicals, but they'll get used to it.  In middle school they are allowed to get a decimal for all radicals.  It's a hard adjustment for them!

First, I had my students write the Pythagorean Theorem in their notebooks.  Then, I used the pink foldable to help them with the steps to find the missing sides of triangles.  I found this idea from Mrs. Atwood's Math Class.  In the original, students wrote on the flaps and drew their own triangles.  I prefer to have things printed, so I made one.

Next, I gave my students a table of the Pythagorean Triples.  I had them work with their partners to fill in the table.  We worked the two problems at the bottom together once they had completed the table.

After that, I used my Pythagorean Theorem Word Problems Task Cards.  I used the "multiple page" option on the printer to print 4 pages to 1.  Each student got 4 problems to work in their notebooks.

The next day, I used my Pythagorean Theorem Converse Foldable to teach about classifying triangles.  Each flap as two practice problems underneath.  I didn't do very much with the rest of the page.  I might include more practice problems or something next year.

Then, I had my students do a Classifying Triangles Card Sort.  They wrote the rule in each category as well.

I liked the way these lessons turned out.  My students understood everything, but still struggled with the radicals.  I'm really working on improving their algebra skills.

    1. My class length has been different in different school years. However, they have all been in the 45-52 minute range.

  5. This is a great resource! I have downloaded the pink foldable, thank you for sharing! ��
    I tried to click the link for the Triples table but it takes me to the foldable again. Wasn’t sure if I was missing something or is this a paid resource in your TpT store?
    Thank you!

    1. It's free. It is in the same file as the foldable. I believe it's page 3 of the document.
