Eraser head

October 4th, 2007 § 0

Alli often requests that we give her mental math problems.  Of late, she seems to have latched onto basic multiplication.  At the first answer to 2 times 2, I thought perhaps she didn’t get the difference from adding, but when she quickly came up with the right answers for 3 times 5 or 6 times 3, I took notice.  Noticing that she wasn’t counting on her fingers and fascinated by the unique algorithms that kids come up with to do math operations, I asked her how she worked the problems out.

Her response:  “Well, it’s like I have a piece of paper and a pen in my head, and I can just write things down and look at them there.”

And a followup:  “Only since it’s a pen, I can’t erase.  I have to cross things out.”

Then: “And I only have room for 4 lines on the paper.”

I then asked her what happens when the lines are full.  She indicated that she has a few more pieces left in her head.  I then asked what happens when all of the papers are full.

Her honest response: “That’s when I throw a fit.” 

Probably the most astute observation I have ever heard.
