[school bell rings]

A stick figure teacher stands in a classroom next to an old TV set and a chalkboard that reads "Shapes" and shows a triangle, a square and a rectangle.

He says OKAY, CLASS,
SETTLE DOWN.
IT'S TIME TO PRACTISE
OUR MULTIPLICATION.
DOES ANYONE KNOW HOW
TO USE AN ARRAY?
NO?
OKAY, HOW ABOUT A JOKE?
WHAT DO COLUMNS AND
ROWS SAY AT A PEP RALLY?
HIP, HIP,
ARRAY!
GET IT?
[class reacting]
ARRAYS ARE MADE UP
OF COLUMNS AND ROWS.
OKAY, WELL, ALL RIGHT,
LET'S JUST WATCH THE VIDEO.

He turns on the old TV.

(music plays)

Several squares with eyes appear on the screen.

Two of them look at each other and sing
DID YOU KNOW...
YOU CAN VISUALIZE
MULTIPLICATIONS
TELL ME IN WHAT WAYS
YOU GROUP OBJECTS INTO
ROWS AND COLUMNS
WE CALL THESE
GROUPS ARRAYS
CHECK IT OUT!

A male voice says 3 MULTIPLIED BY 2 IS
THE SAME AS SAYING
3 GROUPS OF 2.

Three groups of two squares each appear on screen.

The voice continues
SEE, 1, 2, 3 GROUPS
WITH 2 OBJECTS
IN EACH GROUP.
OR WE CAN PUT THOSE
OBJECTS INTO AN ARRAY.

The squares shift to form three rows of two squares each.

The voice continues
AND NOW WE HAVE 3 ROWS
WITH 2 OBJECTS IN EACH ROW.
LET'S COUNT.
3 MULTIPLIED BY 2 IS 6.
LET'S DO ANOTHER
EXAMPLE.
OKAY, 4 MULTIPLIED BY 3
IS THE SAME AS SAYING
4 GROUPS OF 3.
SEE, 1, 2, 3, 4 GROUPS
WITH 3 OBJECTS IN EACH GROUP.
OR WE CAN PUT THOSE
OBJECTS INTO AN ARRAY.

The 4 groups of 3 squares shift forming an array of 4 rows with 3 squares each.

The voice continues
AND NOW WE HAVE 4 ROWS
WITH 3 OBJECTS IN EACH ROW.
LET'S COUNT.
4 MULTIPLIED BY 3 IS 12.

The two squares with eyes sing
YOU CAN VISUALIZE
MULTIPLICATIONS
OH, TELL ME IN WHAT WAYS
YOU GROUP OBJECTS
INTO ROWS AND COLUMNS
WE CALL THESE GROUPS
ARRAYS, ARRAYS, ARRAYS

The song ends and the stick figure teacher says
SO, IT'S GOOD TO USE
AN ARRAY TO HELP YOU
VISUALIZE MULTIPLICATION
BY GROUPING OBJECTS INTO
ROWS AND COLUMNS.
HEY, THAT REMINDS ME.
I WENT TO SCHOOL
ONCE WITH
ARRAY.
YEAH, HE WAS SO STRANGE.
HE WAS ALWAYS GROUPING THINGS.
HA, HA!
[class reacting]
OH, COME ON!
THAT JOKE WAS LIKE
ARRAY
OF SUNSHINE.
