Teacher Feedback

"Very easy for students to walk themselves through. I like the guided questioning process."

"It's difficult finding engaging practice for this standard. This was a good one! Thank you!"

"My students were able to follow along with ease and grasp the concept. "

"I posted the PDF of this worksheet to my Google Classroom after presenting a lesson on finding the Slope Using Similar Triangles. This worksheet is great because the mini questions help guide students to discover that the similar triangles will produce the same slope. I enjoyed using this worksheet."
