Have you heard of Canva? If you haven't, you are missing out! Canva is on fire these days, complete with their own AI tools built right into the platform! It's my new favorite go-to for anything graphic design (sorry Google slides) and especially for creating things with images
Not only can teachers use it, but students can navigate and create in Canva, too! Even better, teachers get a free Canva Educator account, which includes access to the pro library of resources.
