I have become a big fan of loose parts the past three years and have expanded on my supply of them for my home program. I try to rotate them frequently, but always leave out the favorites. The kids used them to embellish block play which includes: unit blocks, magna tiles, kappa blocks and legos. They also are often found in the play kitchen area being stirred into a stew. I am always on the look out for new ones and find many at re-sale shops. Recently I bought a bag of old-fashion rollers to see how the kids would use them.
