This morning, Emily spent over half an hour playing with these four cups.
She singled them out from the rest of the set and focused on just these four.
I sat quietly and watched her play.
She learnt that
Cup 1 fits into Cups 2, 3, and 4.
Cup 2 only fits into Cups 3 and 4.
Cup 3 doesn't fit into Cup 1.
It doesn't fit into Cup 2 either, no matter how hard you try.
Cup 1 can even go into Cup 4 upside down.
None of the cups fit into each other sideways.
Cup 4 is big enough to pretend you're drinking out of it.
Cup 1 is small enough to lick the entire inside of.
All the cups are good for biting.
They are also excellent to bang against each other.
So much to discover!
