What teachers say

From teachers who have used these lessons in their classrooms.

“These are awesome lessons -thoughtful problems that get to the heart of the topics. Easy to figure out which students get it based on the questions that they struggle with.”

Catherine O


“This was an incredible resource that kept my students engaged for an entire 1 hour 30-minute block! The differentiated levels were incredible and allowed me to differentiate for the needs of all of my students. Thank you so much for this!”

Claire G


“This was an excellent resource for my students to use when we went through proofs. I was able to teach the concept one day, and give the activity to them the next day to complete with a partner, and it worked well with them! It fueled productive discourse and students were able to problem solve with one another.”

Kolbie L


“Great unit to teach congruent triangles for my struggling learners. I like how it starts with the concept of SSS/SAS/ASA/AAS/HL and then incorporates the reflexive property, vertical angles, corresponding angles, and alternate interior angles. I also like that the proofs are kept until the end of the unit. Well done!”

Lisa W


“Good Unit! My students did very well comprehending this unit compared to the textbook unit I have used in the past. Thank you!”

Michelle R


“I love the ease of readability of all of [the] resources, they are all thoughtfully laid out and easy to implement.”
