"Do you know how important doctors are?" I ask. "Well, they need math for their job."
"No, they don't," my oldest argues. "They just use science."
She's in for a rude awakening when she reaches Chemistry and Physics.
I may have broken through a little bit, though, with my oldest boy. We were counting change the other day in math and doing a little playacting. "Suppose I bought this from you," I imagined with him as I held up a pen. "And suppose it cost $1.34, but all I had to give you was a $5 bill. What would you give me as change?"
He counted out the change and then suddenly his eyes lit up. "So if you're a cashier in a store, you have to use math?!"
I paused for a minute. Should I let him in on the secret of the 21st century? Should I tell him that cash registers do the work for you? That they tell you how much change to give? That you don't really have to use math to figure it out for yourself?
"You're right, Michael! Yes! Cashiers do have to use math!"
