Kerpoof is a website that I used with my 3rd graders and can be used by K-8 students. With Kerpoof you can spell a picture, make artwork, animated movies, tell a story, make a drawing, make things like t-shirts and mugs, and also earn Koins to purchase things in the Kerpoof store. Kerpoof is mostly FREE but they do charge a membership fee for certain things. There is help for educators like the educators page, lesson plans, and teacher tools. This is a great website for students to learn through their own creativity.
The video embedded below gives a quick overview about Kerpoof.
