Free U: Half and Double

Danny is obsessed with counting. He doesn't always do it in order, but who cares. He's recognizing numbers, even if he sometimes declares that the 24 on our advent calendar is a 42 and then tries to count to that number. He's also obsessed with the number 45, which he sees on speed limit signs and believes must be super fast. (I'll let him believe that one. Forever.)

This morning, he was flashing his five fingers at me, because, you know, he's now five. I'm afraid someone is going to think he's flashing gang signals. So I took advantage of this display to talk about half and double. He's been figuring that one out on his own lately, so I thought I'd build on that.

I told him to put up both hands and count his fingers. 

Then I told him to put one hand behind his back and said, "Half."

Okay, now bring your other hand back; that's double, I told him.

He then put his hand behind his back, then back out front and then behind again, dancing and chanting, "Half, double, butt. Half, double, butt."

Clearly, this is five year old humor.

And that concludes our lesson in math and fractions that I'm pretty sure would end in an automatic time out or stern look in school for potty talk.

He'd probably say that 45 is "too speedy"
