Of course, book access is key. In a perfect world, I'd send all students home with enough books to keep them engaged for the whole summer. (Did you know that Todd Nesloney's school actually made this happen? Read about it here. The whole idea makes me salivate!) I don't have the resources to pull off this kind of miracle, but I do have access to a local library and I have time to spare.
For a few years now, I've donated an hour of my time nearly each week of the summer to meet with my students at our local library. I call it Miss McMorrow's Summer Book Club.
Since I don't want to be locked into a schedule, I simply choose a day and time on a weekly basis that works for me, so parents just have to flexible. One week we might meet on a Friday morning. The next week might be a Wednesday afternoon. I simply send an email and text to parents the day before. I invite them to drop off their child at a certain time and pick them up an hour later. I arrive at the library early enough to choose some good read-alouds, as well as some books I think students would be able to read with independence.
Obviously, my book club won't meet during the week I'm away at church camp, and a few years ago, I abandoned the idea of book clubs altogether. Honestly, it was one of those years x 10, and I needed a break. Otherwise, giving up an hour per week of my summer really feels like no sacrifice at all.
Not everyone has the luxury of time during the summer like I do, but minus incentives and myriad other "strategies" that when analyzed really don't work or align with our beliefs, how will we creatively increase the odds that our readers are readers even when they're not at our fingertips? It's a question worth asking.
