I tracked down my seven favorite ones, along with several others in each category that might work (since everyone's different). Did you know they make planners for elementary school? And while your child might not be writing in playdates, a planner can be a useful tool for you and the teacher to communicate with each other.
One of my favorites just on looks is the Letts of London one here, but there are tons of options to choose from based on looks, features, size and grade level. One thing to check off your back to school list!
