I would agree with you, but I've actually seen the homework assignments and only acceptable correct answers to common core work, and it's disgusting.
Trying to solve 72/9? Better show your work by drawing 72 circles, or you get no credit.

I see no problem taking math out of abstraction in this way, especially as one moves onto visualizing more complex math. Seeing how the symbols interact with their meaning is a good thing.
I recently introduced my 5 year old to Dragonbox. She picked up algebra quickly, without the formalities, of course. I was pretty amazed by how quickly she understood it, too.
Playing with numbers is a really a great way to learn the meaning of formulas. There are entire schools of thought, such as Montessori, that believe numbers should be taught in this tactile way. Seeing it first hand, and comparing it to my own struggles as a child, I'm inclined to see great value in drawing 72 little circles out.
