Sarah stands next to a wall touch screen showing a definition and a maple leaf. She is in her mid-twenties, with short straight brown hair. She wears a blue T-shirt with a print that reads "Home Work Zone" and black tights.

She says HI, TVO KIDS.
TEACHER SARAH, HERE.
AND TODAY WE'RE GOING TO TALK
ABOUT STEM and LEAF PLOTS.
A STEM and LEAF PLOT IS JUST
ANOTHER WAY TO KEEP TRACK
OR TO ORGANIZE DATA
OR SETS OF DATA.
AS YOU CAN SEE, STEM and LEAF PLOT
HAS TWO PARTS: A STEM AND A LEAF
A STEM AND LEAF PLOT
BREAKS NUMBERS DOWN
BY USING THEIR PLACE VALUE
INTO THE TENS AND THE ONES.
AS YOU CAN SEE, THE MAPLE LEAF
HAS TWO PARTS:
IT HAS STEM,
BUT IT ALSO HAS A LEAF.

Using her index finger, she circles the part of the leaf.

She continues ANY TWO DIGIT NUMBER CAN ALSO BE
BROKEN DOWN INTO TWO PARTS,
JUST LIKE THIS MAPLE LEAF.
WE CAN BREAK NUMBERS DOWN,
BY USING TENS COLUMNS
AND THE ONES COLUMNS.
LET'S LOOK AT THE EXAMPLE 45
FOR A SECOND.
WE KNOW THAT THE FOUR IN 45,
IS IN THE TENS PLACE.
AND WE ALSO KNOW THAT THE FIVE
IN 45 IS IN THE ONES PLACE.
SO THE STEM, IN THE STEM and LEAF
PLOT REPRESENTS THE VALUE,
OR THE DIGITS
IN THE TENS COLUMN.
AND THE LEAF REPRESENTS
THE VALUE,
OR THE DIGIT IN THE ONES COLUMN.

She clicks on a top menu and a two-column table appears on the touch screen.

She continues HERE'S AN EXAMPLE OF
A STEM and LEAF PLOT.
THIS STEM and LEAF PLOT
SHOWS INFORMATION
ABOUT THE NUMBER OF PAGES READ
DURING THE INDEPENDENT READING.
I CAN SEE THAT I HAVE
MY TWO PIECES:
I HAVE MY STEM
AND I ALSO HAVE MY LEAF.
ALL OF THE NUMBERS IN THE STEM
COLUMN REPRESENTS
THE TENS COLUMN
OR THE TENS PLACE VALUE.
AND ALL OF MY NUMBERS OR ALL OF
MY VALUES IN MY LEAF COLUMN,
REPRESENTS THE NUMBERS IN MY
ONES COLUMN.
SO LET'S SAY, I WANTED TO KNOW
WHAT A DIGIT WAS.
I WOULD A LOOK AT MY ONE, AND MY
OTHER ONE AND I WOULD SEE
THAT THAT PIECE OF DATA IS 11.
NOW, I CAN SAY, WHAT ABOUT THIS
ONE? CHECK FOR MY TENS,
I HAVE A ONE, CHECK FOR A DIGIT
IN MY ONES, I HAVE A TWO,
SO THAT REPRSENTS 12.
THE SAME THING IS TRUE
NO MATTER WHAT TENS VALUE IS.

She writes down the numbers mentioned and continues SO IF I WANTED TO TAKE A LOOK
HERE, I WOULD KNOW THAT
THESE THREE REPRESENTS THE TENS
COLUMN, OR THREE TENS.
AND I WOULD KNOW THAT THESE
THREE, BECAUSE IT'S IN THE LEAF
REPRESENTS THE ONE COLUMN,
OR THREE ONES.
THREE TENS PLUS
THREE ONES IS 33.
THERE YOU HAVE IT, TVO KIDS.
A STEM and LEAF PLOT.
SEE YOU NEXT TIME!
