Our theme for summer reading (like a lot of the country) is "Catch the Reading Bug". I really like the new Ed Emberley book--"Bye-Bye Big Bad Bullybug".
"Bugs, Bugs, Bugs" by Bob Barner is available in a book/cd set that's so much fun. On kizclub.com you can find pieces to print out to do this on the flannelboard.
I'm also using poems from Rick Walton's "What to do when a bug climbs in your mouth and other poems to drive you buggy". Many of them beg to be recited with puppets or other props.
