Doctor Bean, Stacey, PsychoToddler...get your calculators ready. This one is fun.
Here is a math trick so unbelievable that it will stump you. Who comes up with these things...?
1. Grab a calculator. (you won't be able to do this one in your head)
2. Key in the first three digits of your phone number (NOT the area code)
3. Multiply by 80
4. Add 1
5. Multiply by 250
6. Add the last 4 digits of your phone number
7. Add the last 4 digits of your phone number again
8. Subtract 250
9. Divide number by 2
Do you recognize the answer?
I guess someone's got your number!

My daughter is in third grade. I was in third grade circa 1969.
Math is not her subject. Math was not my subject then, nor is it still today.
She learns new math. I learned old math.
Her logic questions involve adding, subtracting, based on the way the questions read. The questions talk about purchases: purchasing cell phones, purchasing computers, purchasing CD players, purchasing cameras.
My logic questions involved adding, subtracting, based on the way the questions read. The questions talked about purchases: purchasing apples, purchasing grapes, purchasing bananas, purchasing oranges.
As we were working on math the other night, and I came across her logic questions, it hit me: "Ah, that's why they call it NEW MATH." I could just try to imagine my 8-year-old self looking at these questions in 1969 and asking: "What's a CD player, what's a cell phone...?"
