Math "Writing" RAFTs
CRITICAL NUMBERS BY KAYA
MATH RAFT
There once was a feud between two families, The PEM (parenthesis, exponents and multiplication) family and the DAS ( division, addition and subtraction) family. Nobody knew how the feud started and nobody had the courage to stop it.
On a summer day in late August a multiplication sign was born into the PEM family, her name was, you guessed it, Multiply. Two days before a beautiful division sign was born in the DAS family and her name was Divide. They were destined to be best friends they just didn’t know it yet….
On her 10th birthday, Mulitply’s father told her that she could go into the PEM/DAS Woods. Those were the woods that separated the PEM family and the DAS family. Multiply was so excited because she was a curious girl and had always wanted to go in the woods to explore the world outside her family borders. The very next day Multiply went into the woods. She was having so much fun talking to the squirrels and smelling the exponent flowers.
Divide was nothing like Multiply. She was a girl who always followed the rules and was a bit fearful of new things. On this same day Divide ran into the woods chasing after a lost ball. She couldn’t find the ball and was searching everywhere when suddenly Divide saw something move in the bushes. She screamed as Multiply tumbled out of the bush. “Thank goodness, I thought you were a PEM. WAIT, you are a PEM,” Divide yelled in horror.
“Step back, I know karate,” said Divide.
“I’m sorry I frightened you but just because I’m a PEM doesn’t mean you have to Karate chop me. You know DAS’s aren’t that perfect either,” yelled Multiply.
“Well at least I don’t jump out and scare innocent operations!”
“I didn’t jump out! Mr. Squirrel accidentally bumped into me and I tripped over a rock!”
“Well you don’t have to get all defensive!”
In the middle of all their fighting they heard rustling in the bushes.
“Maybe it’s one of your parenthesis friends,” Divide teased.
“Shh, it sounds like some algebra.”
“Eeek I hate Algebra, it’s so scary!”
Suddenly a numerical expression jumped out from the bush.
“AAAAAHHHHHHH!!!!” both of the operations screamed hugging each other helplessly.
Fortunately the expression got tangled in the bush and couldn’t get to the girls. This caused the two operations to start laughing hysterically.
“I almost peed my…body” Multiply said barely able to speak. From that day forward, they formed an unbreakable bond. The also had the courage to break the feud and become…. PEMDAS
And that, ladies and gentleman, was how PEM DAS came to be.
Ms. Z's Sample Math RAFT: An unrequited love story of numerals separated by grouping symbols. On the outside, looking in. Looking upwards to that curving and cozy line that separates us... From them. Knowing you're in that grouping symbol is difficult for me, knowing that my only hope to be let in, to have that parenthesis disappear, means that you're no longer you. You'd be a product of you and something else.
And who is in there with you anyway, my sweet one. Is it that brash eight, who mocks my linear form, boasts of his proximity to that double-digit ten, so revered, a factor to so many. Or is it that shifty five, its contrast of curves and angles. Yes, yes. It is that 5, so well know a math fact is he.
And who made these rules, this order, anyway? That some operations get privileges different from the rest is not just unfair, it’s illogical. Do I have a lesser value than other numerals simply because I have a lesser value than other numerals? Standard form can be so unfair. Perhaps if I was represented as a fraction whole, I might garner the respect of that elite group within your grouping symbol, dear one.
Oh that multiplication sign, so varied in its representations, so practical an operation for so many. Why can’t I be a factor, too? And not just an addend. To see you in there, one, amongst the snobbish and boastful values… they know nothing of your complexity. Our kind is neither prime nor composite. We are unity, the integer between two and after zero. Natural numbers, you and I.
After peeking my eyes above your fencing parentheses, I see who is in there with you. It’s 5 and 2 and you, darling 1. Three factors whose product is 10. Alas, the heavens shine upon me! For you times them plus me is 11. Together again.
