Building high towers out of the cardboard blocks is fun for kindergartners. The only problem is...their ambitions are taller than their bodies. I allow them to carefully use stools or chairs to get their building taller.
However a well-constructed tower isn't wobbly even at those heights. They know they could get their building taller, if only they could reach higher. It's fun to watch them problem-solve this and see the idea appear in their minds that they could recruit a taller person to help.
I'm always happy to oblige if asked to add a few blocks to the top of a tower they've created. Here's one that went up Friday.
Sad to say, they didn't work quickly enough to put the blocks away before time ran out—more than a few students continued to play when it was time to clean up—so these blocks shall stay on the shelves on Monday.
