Hi Laurie,
In our district, librarians use Padlet for students to share their adventures with the library mascots--flat Mr. Wiggles for Kindergarten, Scaredy Squirrel for 1st gr, and Benny the Woodpecker for 2nd gr. Over the summer, I had students print out Flat Librarian to take on reading adventures (and use as a bookmark) and students posted adventures on a Padlet.
I have also used Padlet for book reviews, a way to comment on dig cit lessons, word art for MLK One Word, and for Dot Day students posted how they plan to make their mark on the world. I have been using Padlet since it was Wallwisher--please reach out if you want more ideas.
