Are you ready to Stash some Trash? In this app from PEEP and the Big Wide World, which features the loveable and plucky robin, Chirp, one bird’s trash is another Raccoon’s treasure. Since Chirp is in a “sorting mood,” kids get to help Chirp make order of her world starting with Raccoon’s junk.

In this Trash Stash app, kids practice their categorization skills by sorting objects using increasingly sophisticated criteria. The game begins simply with sets of colors but as kids are successful, it gets trickier with more complex sets like Things You Can Eat and Metal Things.

Players might notice that objects can fall into more than one set. A red apple might be in the Red Things, Things You Can Eat, and Things That Grew sets. Older kids may also get a kick out of trying to guess what the set will be before it's announced. They can do so by watching the items as Raccoon hurls them from his hideaway.

The PEEP and the Big Wide World Trash Stash app from WGBH was produced by WGBH, the producers of PEEP and the Big Wide World, with additional development work by CloudKid. The animated series PEEP and the Big Wide World gives wings to the innovative idea of teaching science to preschoolers. Wry and distinctive visual humor, charming plotlines, and lovable characters combine with a comprehensive science curriculum to attract and engage kids three to five years old.
