I like the "less is more" concept. Too much can be overwhelming for kids. i.e. many of my things count in many areas for multiple ages in the FCCERS-R book. I like having all things be accessible for all ages with the exception of some smaller-piece manipulatives the older kids use or some puzzles with smaller pieces or certain art supplies. I have a change-out system of what and how many to place back similar to what I rotated with....i.e. shells for pine cones in the science center.
