This curriculum guide has many resources offered to teachers throughout. It is very comprehensive and takes teachers throughout the entire unit of teaching the Pythagorean Theorem, which I appreciate. It includes and considers every part of a unit you would want to include and takes into account the little things needed in a unit. It starts with different ways you can start introducing the topic. Not only does it have many different ways to include technology in your lesson, but it also has different accommodations throughout, which I really like. In the "Application" section, the lesson includes a hands-on activity to help students work through actually using the Pythagorean Theorem in real-life situations which I LOVE. I also love the inclusion of Online learning options at the end, as that is very practical for the classroom today. Overall, this is very well thought out and there are a great number of resources, accommodations, and good tidbits throughout to help teachers construct and teach a unit on this topic.

This curriculum guide provides a comprehensive coverage of the Pythagorean Theorem.
It includes good comments about exactly how resources could be used and their strengths and weaknesses.

The “Prove it” exercise in the “Preview” part of the curriculum is “free but not open,” designated “read the fine print.” To enhance it, I recommend (since links don't work in comments, I made a remix of the lesson and added these): have posters of perfect squares and cubes on the wall (from -- has more posters and ideas ), and would provide students with a times tables chart up to 20 ( )

The mini-flexbook is very well grounded and comprehensive, including pictures and illustrations of “right triangles” in the real world.

The “prove it! Part 2” has an excellent practical example of using the Pythagorean Theorem to construct a deck.

Great collection of resources!

This guide gives a teacher everything needed to comprehensively cover the Pythagorean Theorem in the Adult Ed classroom. I like the easy to follow progression of resources. Shana has curated a worthwhile collection.
