LessonKeeper is a virtual lesson notebook that lets you stay in-sync with your students, whether you’re doing lessons online or in person. Easily create shareable lessons filled with text, images, audio, YouTube clips, PDFs, and more. Then, send the lesson to your student via email, Messages, or any other system where they can receive a link. The student doesn’t need an app to access the lesson — all they need is an internet-enabled device that can access a webpage. Students can view the lessons on their device, including listening to sound clips you’ve recorded, watch embedded YouTube videos, etc. Plus, if you edit the lesson, the student sees the edits without you having to send the information again — it just appears on their lesson.
