I was recently searching for some author interviews to share with my 4th Grade Writing Club, specifically ones that talked about the craft of writing in ways that might be accessible and useful to them. Here are our two favourites:
This website is a wealth of information and resources. It's focused around World Book Day, which will be on 1 March 2018. Our group especially liked the Cressida Cowell interview.
NBC Learn has a page full of interviews with children's authors. We watched and discussed the Jacqueline Woodson clip but they are all interesting and super accessible. It was published some years ago but much of the advice and thinking is timeless.
