One Box, Anything
A big box, some tape, and no instructions whatsoever.
The building is fine. The knocking down is the whole point.
Stack anything you have into the tallest tower it will make, then let them demolish it. Repeat until they lose interest.
This is a childs first physics lesson. Stacking teaches balance, cause and effect, and the beginnings of planning. The countdown before the knock builds anticipation control, which is early self-regulation.
Keep towers below head height and use soft or light items for the youngest children.
Make the tidy-up part of the game by racing to see who can put more pieces back in the box.
A big box, some tape, and no instructions whatsoever.
A trail of clues around the house, ending in something small.
One box, one slot, and a toddler who will not stop posting.
Freeze small toys in a tub of water and let them dig them out.
Every blanket in the house, one afternoon, one secret headquarters.
A tube taped to the wall and a basket of things to drop through it.
