The SCBWI, of which I'm a longtime member, has created a directory that has hundreds of resources by published and listed (PAL) authors and illustrators that includes activities, art lessons, audiobooks and ebooks, bilingual resources, online book readings, emotional and mental well being projects, podcasts, teaching guides, and virtual visits and workshops.
By the way, I have a page in the "Art Lessons" section call "Coloring Pages Featuring Plants and Animals of the Sonoran Desert and Colorado Plateau." It features images to color as well as and facts about southwestern flora and fauna. I will be adding a new page every Wednesday for as long as needed.
Here is the direct link to my page:
