What's the largest number you can represent with 3 digits? Nope. It's not 999.

This post is about my fight against "Standardized Testing" in math, and what later became "Common Core." It goes back to 2008 when my daughter was in grade school. I got a call to come to the principal's office. I was surprised, as this was a real first. Like all fathers I suppose, we tend to think of our little girls as angelic and saintlike. In my case, this was the absolute truth.

"Your daughter was being disruptive in class."

It was like an arrow through my heart. I looked over at her. There were tear-streaked marks all down her face. She looked down at her shoes when I shot a glance over at her. And she started sobbing again. The principal continued his monotone diatribe, while I walked over to kneel besides my daughter and hug her.

"Really, Mr. Trice, that's not appropriate..."

I continued to ignore him. "Are you OK?" I asked her. She looked up, nodded her head, and sniffled.

"Tell me what happened" was all I said as I tried not to stare through the principal's skull with my X-ray vision superpower.

"Your daughter tried to correct her math teacher. The teacher explained why she was wrong, and she insisted that she was correct."

I laughed.

I knew she was right and the teacher was wrong. I couldn't wait to hear this one.

"What was the question?" I asked as the principal was about to interject a rebuke to my outburst.

The teacher was also present, and he spoke up. "The question was, what was the largest number that can be represented with 3 digits. I said it was 999, your daughter disagreed."

I remember thinking "Uh-oh. What the heck was she thinking?"

That's when she spoke up, anger in her voice, "Oh yeah? Tell me what 9 raised to the 9th power raised to the 9th power is then??"

Holy crap! She was right! Technically, the problem is not asking for the largest 3-digit number, which is exactly where my mind went upon hearing the question. The question is asking you to represent a number using 3 digits, so exponentiation cannot be ruled out.

I looked over at her and smiled and said "Way to go! You're 100% correct!" And I gave her a high-five. She smiled. Then cried some tears of joys as she laughed. She knew I had her back.
