The Goofballs are 4 kids who work together to solve mysteries. There are two boys and two girls who work together to find mysteries, wear disguises, and have a fun time together. There is humor and word play throughout the books that are perfect for this age.
The language is classic detective language. I'm not sure the kids will pick it up but it is very well done and the simple sentences are a great support for readers newer to chapter books.
I am so excited that I discovered this series. It is a great series for readers new to mysteries--I never seem to have enough mysteries to recommend to this age but I'll definitely be recommending these.
This series is fairly new (2012) with 4 books out so far. The 5th is due out in August. I just bought the next three and am thrilled to add these to my classroom collection!
