CHILDREN, IN ALGEBRA YOU WILL ENCOUNTER SOMETHING UNUSUAL, LETTERS REPRESENTING NUMBERS. THESE LETTERS ARE CALLED VARIABLES. VARIABLES ARE FOUND WITHIN EXPRESSIONS TO CHALLENGE AND BROADEN…YOUR MINDS…

EXPRESSIONS, EXPRESSIONS ARE MAKING BIG IMPRESSIONS

7 x n = 49
NOW TELL ME WHAT TO FIND, USE YOUR MIND USE YOUR MIND
(n) IS A LETTER WHO IS BETTER WHEN YOU FIND
WHAT HE REPRESENTS, REPRESENTS, REPRESENTS
7 x (WHAT) = 49?
IF YOU KNOW YOUR MULTIPLICATION YOU’LL BE FINE YOU’LL BE FINE

IF I SAY “NOW LITTLE STUDENT LITTLE STUDENT WHAT’S 5 MORE THAN A NUMBER?”
YOU CAN SAY IT BACK TO ME BACK TO ME, “TEACHER, TEACHER, TEACHER, TEACHER
THAT’S A LETTER NOT A NUMBER NOT A NUMBER NOT A NUMBER?”
WHEN WE DON’T KNOW THE NUMBER USE A LETTER THAT IS BETTER
A VARIABLE IS A LETTER THAT IS BETTER THAT IS BETTER
n + 5 OR 5 + n = IT’S SO EASY IT’S SO EASY LEMON SQUEAZY
