Easy as ABC

As I was cleaning up dinner last night, Peter approached me with some questions. The questions came in the form of a song, sorta of. He had a tune that accompanied each question.

"Mom, what shape is this?" holding up a square block. "Alright."

"Mom, what shape is this?" holding up a triangle block. "Alright."

He continued asking the shape of each individual block.

Then he held up a cup, and circled the rim with his finger...."What shape is this?"

I passed with flying colors. I think.....

"Good job Mom, now you know all your letters!"
