My mom gives the grandkids money when they finish a book and write or tell them what it was about, favorite parts, etc. This is the first summer she has added my 8 year old in the mix (so far its been my brothers older kids that do it). My son isn't the biggest reading fan and has struggled with it. So I would like to find some easier chapter books for now that he could enjoy, practice reading, and get the reward from my mom while hopefully getting him to actually enjoy reading a little more, gain confidence, and not get frustrated struggling to much. He's done Magic Tree House but gets frustrated with some of those. Do you know of any chapter books/series that are easier then Magic Tree House?
