Cleaning up can be fun if the process is not a frustration one and there is plenty of good humor and rewards in the classroom. And a big clutter buster and frustration buster is simply having the right storage units for the job. A neat and organized classroom leaves your students in a better frame of mind to concentrate on lessons without distraction or frustration. Most good child storage units contain bins that are colorful and can be labeled. And you can choose from open bins or closed.
