Box With Sliding Lid

The Box with Sliding Lid sets a toddler two jobs at once: post the object through the opening, then slide the lid back to get it out again. A closed lid hides what was there a moment ago, an open one proves it stayed put, and the whole cycle repeats as often as the child wants. Sliding asks for a different movement than a hinged lid, a sideways push that trains wrist and shoulder control. For toddlers in the first three years.
