Tomorrow (Saturday) is Free Comic Book Day. Go down to your nearest comic book store (do you have one?) and grab a few free comics. They’re not always the very best comics, to be honest, and you may need to make sure they are appropriate for whatever age kids you are going to share them with, but … did I mention free comics?
The website for Free Comic Day (now 10 years old, apparently) has more information, including a handy tool to find comic book stores where you live. I usually go with my sons, and we all get handfuls of comics. I bring mine into my classroom for my students. They love it.
