Dale and I studied 3-d shapes recently.
Or Geometric Solids, as our poster says. :)
Whatever you want to call it, we were learning how a square you can hold is a cube, and a circle you can hold is a sphere ('sa-fear' by Dale's pronunciation).
I gathered a few examples from around the house, and as Dale got the idea, I sent him to find his own.
After he went in search of a cube, I kept hearing a ka-clunk, ka-clunk, bump, thunk making it's way slowly down the hall back towards me.
Want to guess what Dale came back with for his cube?
A whole table! (The blue one pictured below)
