Happy Snappy Algebra by Susan Cantey
On the road I often think
“How long until I sleep?”
Then I see how many miles are left,
And divide by my vehicle’s speed,
But when I’m driving in the car,
And junior says “Are we there yet?”
If daddy answers “About an hour,”
He’s not doing algebra.
Happy snappy algebra,
Do it all the time,
Happy snappy algebra,
It’s so fine.
Once I needed some cement,
So I went to the store,
Bags came in many sizes,
Forty, eighty pounds or more,
So I went back home to measure,
Used my calculator,
No need to be perturbed,
My algebra was superb.
(chorus)
Let’s party!
Let’s have a pizza party,
How many should I buy?
(I don’t know.)
A small one feeds 15,
A large, 25.
I don’t like these cell phone people,
They have too many plans,
They try to make me pay a lot,
What kind of fool do they think I am?
So I drew some graphs before I bought,
Decided how many minutes I ought
To use each day, each month, and then I thought
Algebra helps me a lot.
(repeat chorus twice)
Adding Signed Numbers
By Susan Cantey
When adding signed numbers,
Think of it as cash,
Negative, you owe someone,
Positive, you have,
The answer is the balance
Ahead or behind,
You’re in the black when you’re positive,
Red’s the other kind.
Positive plus positive is always positive,
Negative plus negative is always negative,
But when you’re adding one of each,
Do yourself a favor,
Subtract their magnitudes
And keep the sign of the one that’s “greater.”
When adding signed numbers,
Never get uptight,
Negative moves left,
Positive moves right,
Always start at zero,
Then take one step at a time,
You’re standing on the answer,
When you walk the number line.
(chorus)
8 + -6 is 2,
Cause 8 has the greater magnitude,
-9 + 5 ‘s -4,
Cause between the two, 9 is more,
-5 + 2 ‘s -3,
It quite elementary.
