Empty food containers - use the container for pretend cooking or to play grocery store.
Bed sheet - toss a flat sheet over a table for an instant tent for camping or for a reading nook
Old technology - use old keyboards, phones, and other technology for office or communication play.
Kitchen utensils - mix in "real" mixing bowls, spoons, spatulas, cookie sheets, and cutting boards with play dishes for more cooking possibilities
Boxes - use old mailing boxes to pretend to pack and move
Tools - use tape measures, goggles, and work aprons from the hardware store to enhance play with pretend tools
Draining rack - add a real draining rack to a dishpan of water to wash dishes.
Purses and wallets - adding purses and wallets from the dollar store or thrift store can enhance all kinds of shopping play
In many cases, we don't necessarily use something in a completely different way. But we use "non play" items for play. Look for ways to repurpose different items and real tools to create even more fun possibilities in your dramatic play center.
