I am not sure this constitutes "creative," but I used Padlet often as a way for my students to respond to read-alouds.  I followed the Book-Head-Heart approach from the book Disrupting Thinking by Beers and Probst.  I make three Padlet columns entitled Book, Head and Heart and students type in their responses.  For "Book", they can name a character, identify setting, or summarize plot.  For "Head," they generally answer "What surprised you in this book?" or "what did I notice?"  (I love seeing what they notice in illustrations. So perceptive.)  For "Heart," students share how the book made them feel, but they can also share what lesson they learned or how the book will help them to be better.  I did this with second graders on chromebooks.  It could be scaled up for older elementary.  I also personally like Padlet or organizing thoughts and images from conferences.  Kids might be able to use it as a graphic organizer for research projects by creating columns. I hope this is helpful.  If you haven't read Disrupting Thinking, here's a link to more information on it.  I found it very useful.

Stay well!
