| UNION won!!
As did Belding, Greenville, Lowell, and Tri-County!!
And my sister won her basketball game too! What a great day for my highschool sports teams! | | |
| Today I got an applause from my students for explaining something to them! We were talking about dividing, specifically about dividing by zero, which we all know is undefined -- but do we understand it??
I told them an example about cooking. Suppose I have 30 cups of flour, and I want to make cookies which use 2 cups per batch. How many batches can I make? This leads to the fraction 30/2, which is 15 batches.
Suppose my recipe calls for 1 cup? 30/1 = 30 batches
Suppose my recipe calls for 1/2 cup? 30/(1/2) = 60 batches (an excellent way to visuallize what dividing by fractions means!)
Now suppose I want to make no-bake cookies and my recipe doesn't use any flour, how many batches can I make? 30/0 = ??? You can't really tell! It's undefined -- I might be able to make an infinite number of cookies, assuming I had all the other ingredients....
Anyway, the kids enjoyed the real-life application of math, and gave me an applause. Well, two kids. But still, it was clapping. And it brightened my day! | | |
| Hey 'yall,
FIRST DAY OF CLASSES!!! It was really cool! I love my kids!
I must admit... when I first saw all the freshman, my first reaction was that they are soo -- dare i say it -- cute! They are so small and scared and like little kittens!
Of course, by second hour they learned everything and were plain ol' cats, but those first few minutes.... 
Anyway, can't write now 'cause its WAY past my bed time of 10:00. Will post mo' tomorrow.

| Nothing much to say today. My cat Newman is crazy. He learned that if he runs really fast onto the floor rug he can have it slide across the linoleum - and then it gets all bunched up. So then he crawls under it and just sits there ... waiting ... to pounce on unsuspecting victims that he must think can't see him because he's under the carpet. But that big bunchie in the carpet (with a tail that swings back and forth) isn't hard to miss.

| So, strange little thing reminded me of mom today. I was cutting a pie that we had for dinner today. Normally I cut a pie in half first, and then cut one half into 4 pieces. All my life it has worked perfectly because each of us gets one piece, and the entire half is gone. But today -- for a second I was frustrated because though I had done everything correctly - the whole half wasn't gone - there was a piece left. We don't use up a whole half anymore - there's this odd piece left out.
Of course, I didn't let me bother me too long - I just ate that piece.
But it frustrated me because there's no easy way to cut things into thirds. Halves are easy. Fourths are easy. But thirds is just tough. How do I cut a pizza so that everyone in our family has an equal number of pieces? I have to learn to cut in sixthes now.... It just isn't the same.
I suppose I am being too much of a math geek - but I figured if you're reading this, you were wondering what's going on in my head, and that's what's going on.  | Currently Playing
