Math Works

This morning my son came upstairs carrying the Children's Museum magazine and asking if the Hot Wheels exhibit was there yet. So we looked through the magazine and, using addition, subtraction, and multiplication, figured the following facts about when the Hot Wheels exhibit will arrive:

I noted that the exhibit will arrive on May 26th, so being lazy, at first we estimated that the exhibit would be there is approximately 3 weeks (or 21 days). But then, by using the date at the bottom of my computer screen, we discovered that it will be exactly 18 days, thereby learning that the exhibit will be there in less than three weeks. Then I drew a number line and we learned that the exhibit will arrive in 3 fewer days than 3 weeks. And that, if 2 weeks equals 14 days and 3 weeks equals 21 days, that 18 days is approximately 2 1/2 weeks. Then we talked about how 7 plus 7 plus 7 could also be written 7 times 3 with both problems equaling 21.

(Have I mentioned how much I love homeschooling?)

And then I took this picture of my 7 year old sporting a lovely edition of bedhead and wearing his size 5T pajama shirt, which he insists still fits him just fine.
