This one is harder to share, because you have to have a (free) account to access the activity library, but if you are part of the Seesaw community you will be able to use and share hundreds of premade lessons with your students using the Seesaw app!
This would be great for PD - I don't know how many teachers are aware of this site created by the DPI for teachers (and librarians!) to share lesson plans, activities, and even library pans.
