Does Any of This Sound Familiar?
You know what you want your Geometry students to learn, but turning that into a great lesson with meaningful practice takes way more time than it should.
You've spent hours creating lessons and activities from scratch, digging through Google, your textbook, and old files trying to find something that will actually work for your students.
You have a solid lesson planned, but sometimes you wish you had another way to explain a difficult concept, a different activity to try, or a fresh idea to get your students engaged.
You're tired of spending your evenings and weekends creating, searching, and piecing together materials when you'd rather be doing just about anything else.
Because your time is valuable, and you shouldn't have to spend it creating everything from scratch.
That's Why We Created Your
Geometry Sidekick
Made by a Geometry Teacher, for Geometry Teachers
Every lesson in Geometry Sidekick was made by a Geometry teacher with two decades of experience. The diagrams are drawn, the practice matches the notes, and every answer is worked out step by step, so each lesson is ready to teach, not just ready to print.
A Geometry-Specific Resource Library for Teachers
You shouldn't have to spend your evenings searching for ideas, creating lessons from scratch, or piecing together materials just to be ready for tomorrow. Whether you're a newer teacher looking for a place to start or an experienced teacher who simply doesn't want to create everything yourself, Geometry Sidekick is here to make your life easier.
Get Ready-to-Use Geometry Lessons & Practice
With Geometry Sidekick, you get ready-to-use lessons and practice activities designed specifically for high school Geometry, so you can spend less time prepping and hunting for materials, and more time focusing on your students.
Built Around What You Need
New resources are added monthly, built around what Geometry teachers are looking for, so the library keeps growing around what you want. Geometry Sidekick is the go-to resource you can count on all year, from the first lesson of your course to the last.
You Don't Have to Do It All Yourself Anymore.
Let Your Geometry Sidekick Be in Your Corner.

What Teachers Are Saying
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.
