So this just happened on my way home from lunch with my two boys in the van.

They are G who is 7 and C who just turned 6. And to be fair I am a math teacher, and we do talk math often (usually in the van). This is just the first time I am writing about it.

G: "There is 60 minutes in an hour C. If you take one minute away you would have 59."

Me: "That's right G. And if I took 7 minutes away from 1 hour what would you get?"

Pause

G: "53 minutes"

Me: "Nice. What if you took 10 minutes away?"

G: "That's easy. 50"

Me: "20 minutes way?"

G: "Easy. 40"

Me: "G, if you had 1 and took away 3, where would you end up?

Pause

G: "At minus 2"

Me: "How do you know about minus numbers?"

G: "From the winter."

Me: "What do you mean?"

G: "When it's cold the TV says it's minus ten."

I wonder how far I can push it.

Me: "So G. If you started at minus 2 and took away 3 more where would you end up?

G: "Minus 5."

Me: "If you started at minus three and added 5 more where would you end up?

G: "2"

We pull into the lane way.

C: "Dad did you know 3 is in the middle of 1 and 5.

Me: "Can you tell me two other numbers 3 is in the middle of?

C: "1 and 6."

Me: "Not quite C. If three is in the middle then you need to go the same amount on each side of it. So with 1 and 5 we go over 2 each way. So C when you said 1 and 6, for 6 you went over 3 from 3, and for 1 you went back 2, so 3 is not in the middle of those two numbers"

G: "So nothing and 6."

C: "So 2 and 4."

Me: "So how far did you go over on that one?"

C: "1"

Me: "Nice. So if we went over 10"

G: "13 and....."

Pause. This is the moment.......

G: "Minus 7"

Me: "Nice G. OK boys let's go in. Mom's going to be home soon and we need to clean the house."

C and G: collective "awww"

As we are walking in C: "Dad can we do some more math?"

Nice!!!!

So Mr. Danielson- surprising? What I should expect at this age? Other thoughts?

From circle man to triangle man! Love your work.

Triangle Man is indeed wonderful, and so is the kid snippets site, although admittedly not as educational, just hilarious!
