Jack: What’s 60 + 60?
me: 120. Just take off the zero and do 6 + 6 then add back the zero.
me: What’s 6 + 6?
me: Add back the zero
me: But you don’t say it like that. Write it down. 120.
Jack: Ohhhh one hundred and twenty.
me: Yes! (maybe he’ll be math smart too?)
Jack: But if 50 + 50 is one hundred, then how come 60 + 60 isn’t 300?
me: Uhhh… Because it’s 120.
me: 150 + 150 is 300. So if you have 50 + 50 and that makes one hundred…you just add 10 to each side, so that’s 60 + 60. Or you can add 20 to the original hundred and that’s 120. (I’m losing him)
Jack: So if I want to add 150 + 150, just take off the zeros right?
me: Okay, try it and see what you get.
Jack: 15 + 15. And that equals 30. Then you add a zero to make 300.
Jack: Ohhh now I get math. To make the BIG numbers you have to MINUS stuff first! That’s easy!
me: That’s not exactly it… Why don’t you go READ something.
