Snotty Dotty
(multiplying integers)
There once was a
girl,
Ohso cold cool,
Left trails of ice cubes,
All around school...
And when she
got A's,
On any math test,
She bragged all day,
She claimed to be "best..."
Her
name was Dotty,
She thought she was great,
She thought other students,
Just couldn't rate..
Multiplication quiz?
"Easy!"
Said Dotty, the girl,
As pencil point twisted,
Her hair in a twirl...
But when she
looked at the quiz,
Which lay on her desk,
She didn't have answers,
She'd just have to guess...
What made it so hard,
Why was it so tough?
What made this math quiz,
So tumble and rough?
One number
was positive,
The other was not,
Positive times negative,
Confused Mrs. Dot...
I can't figure these out,
They're not like I learned,
I need some math help,
I feel really burned..."
But no one helped Dotty,
Because Dotty was cruel,
No one helped Dotty,
Ms. Snotty at school...
So she sat at her desk,
Feeling all queasy,
Searching for answers,
Though answers are easy!!!
In multiplication,
If signs are the same,
A positive answer,
Is your end game...
Even two negatives,
Because signs make a match,
Give answers that end,
In the positive batch!
But if signs are opposite,
Like the words,
Get & give,
You will sure see,
You get negative...
Should we help Dotty,
Do her math quiz?
Ok, let's teach her,
Who's a math whiz...
