Our Puzzles and Games shelf actually holds several centers: Puzzles, Games, Bucket Blocks, and Playdough. We have lots of floor puzzles, regular puzzles, and games (I buy most of these at yard sales). Bucket Blocks are bins of magnet blocks, Bristle Blocks, Lincoln Logs, and small wood blocks. Our Playdough Center also changes during the year. I add seasonal cookie cutters, letter/number cookie cutters, and laminated cards that students use with the playdough.
