A twist to 'Egg in a cup'

What was meant for babydoll to play, turned out to be a simple lesson for sonshine.

I prepared this Egg in a cup activity for babydoll.

Sonshine had other plans. I watched him took out each volumeric solids and tried to fit them into the cup.

He discovered that the cube and rectangular solids couldn't fit into the cup.

We discussed why this was so. I pointed to him that only the round bottoms would fit into the cup which had a circular mouth while the others wouldn't because they had  differing bottoms.

Isn't it amazing that the children can create their own lesson plans just by exploring and us just observing? It would have been a shame if i had stopped him and insist edthat he plays the way i had planned it. We would have lost a meaningful lesson!
