The next picture shows the top of our largest bookcase. We keep games we play often in a tub on top. The laminator is there too. On the top shelf you see tons of those hard pencil boxes. These hold our math manipulatives by type: pattern blocks, dominoes, counting bears, linking cubes. There are a few more games, chalk for the chalkboards, etc.
This is a shot of that same bookcase from further back. Those binders of supplies are on the 2nd shelf from the bottom on the right. The blue magazine holders on the next shelf up are the workboxes for my preschoolers. Yes, I know they are backwards! The kids turn them backwards after they finish the box so they can easily see what boxes are finished.
