ABBIE'S CANDLE

She made a movie with a
Romantic candlelight dinner.
Which candle will burn out first?
Which candle will be the winner?

Centimeters at the beginning and,
Candle B is ten

PALINDROME SONG
Chorus:
Go forward then go backward.
If the number reads the same, then it's a palindrome.
Go backward then go forward.
If the number's still the same, then it's a palindrome.
It's not a palomino on the western plain,
Where cowboys love to roam.
No! The wonder of all wonders, a backward-forward number.
It's called a palindrome!
First Verse:
Let's see! Take a 33! Read it in reverse.
Hey it reads the same, So it's a palindrome.
And 505, or 2002,
So they're both examples of that one I love.
It's a palindrome! It's a palindrome! It's a palindrome!
(to Chorus, except say:)

SYSTEMS RAP by Algo Rhythm
(Verse 1 intentionally omitted)
Verse 2:
y equals mx + b
Ax plus By is C. Different forms you see
Plug in mx and b for y in the Ax plus By is C
Which becomes an equation with just x
You know how it be.
Wait. x we need y, don't

the gate, at this rate,
find the ordered pair
x and y are mates
Substitution.
it's not Subway
But I be keeping math fresh
all day every day
Weird flex but okay
Mr. Walker goin' cray
With my words on play
And all I have to say is
Chorus: (x2)
I'm on a mission
Solving systems
Of equations.
Don't be hatin'.

Today is Pi Day, a key day on the mathematical calendar. I have much to say about how I celebrated it in the classroom this year.
But first things first -- I received the dreaded pink slip today. I've been expecting this ever since I took this job in the first place. Recall that last year I got the pink slip, and I wasn't rehired until July. So I already know that I got the last open position, placing me right at the bottom of the seniority list. And enrollment is declining everywhere -- there were fewer babies born in the Great Recession, and that's the generation that's now reaching hi ..read more

Netflix charges 14 plus 1 per film.

This is a repeat of a song I performed a few months ago -- I describe it in my October 19th post. Indeed, I played it in the fall for my Math III class -- and in that post, I even wrote that I'll be playing it again for Math I someday, once that class reaches the chapter on systems. Well, someday is today.
I don't provide a Mocha l ..read more
