Loved by teachers and coaches

I like the name "Coteach" because it's like you're talking with a coteacher—just not your teammate down the hall. This is a collaborative effort, and having somebody who can collaborate with me at this level so quickly to meet the needs of my kids—that's the beauty of it.
BretGrade 3 teacher
As someone who has done so much of this work by hand for 25+ years, having a tool to automate some of the more tedious tasks (like creating a visual vocabulary reference sheet) allows me to put my time into my students and the real preparation of planning and teaching lessons.
AmyGrades 7-8 teacher
Coteach makes me feel like I'm doing a better job of differentiating and providing the practice that my students need, rather than spending so much of the day feeling overwhelmed and like I'm not doing my job very well, you know?
BetsieGrade 5 teacher
I like the ability to generate ideas and resources to support all learners. I love being able to ask for something for a specific IM lesson and have the initial creation done for me. Then, I can just edit and adjust to fit my students' needs.

Coteach creates fluency drills for me every day. That has been game-changing because last year I created all this by hand myself.
Algebra I teacherCalifornia
Coteach has helped differentiate access points for students in my inclusion classes this year, as well as challenge students in my pre-algebra courses. Ultimately, it helped my countless ideas come to fruition while saving me the time it used to take me to develop them all from scratch!
6th grade teacherDelaware
I use the app to create lessons for students who are below grade level or struggle to read English, helping me fit a full lesson, supports, and a cool-down into a 57-minute period while keeping the language accessible—I'm excited for the new updates, especially the graphics!
Jess LampertTeacher
Coteach has helped me boost my productivity, spark creativity, and enhance accessibility when modifying math activities for my students.
Jason HorowitzTeacher
Coteach helps my teachers strategically cut a lesson or activity while still maintaining the integrity of the IM lesson or unit. This saves an immense amount of precious planning time.
