Teacher Charmain stands in a studio next to a large touchscreen. She has long black hair in a ponytail and wears a blue shirt with a print that reads "Homework zone."

A caption reads "Teacher Charmain."

Charmain says HI, TVO KIDS.
IT'S TEACHER CHARMAIN HERE.
TODAY WE'RE GOING TO LEARN
HOW TO ADD LARGE NUMBERS.
THREE DIGITS BY
THREE DIGITS.
SO LET'S DO AN
EXAMPLE TOGETHER.

A chart appears on the large touchscreen. The columns read "Hundred thousands, ten thousands, thousands, hundreds, tens, ones."

Charmain says SO LET'S GET THE NUMBER 368..

She writes each digit in the corresponding column, then says
AND WE'RE GOING TO ADD THAT
TO ANOTHER VERY
LARGE NUMBER, 279.

She writes the number below the other one and says
SO I'M GOING TO USE THIS
PLACE VALUE CHART TO HELP ME
BECAUSE WHEN WE'RE ADDING LARGE
NUMBERS, WE WANT TO MAKE SURE
WE'RE ADDING THE RIGHT DIGITS
IN THE RIGHT PLACE VALUE.
SO I'M GOING TO PUT A LINE
HERE AS MY EQUAL LINE
TO LET ME KNOW THAT ANYTHING
BELOW THAT IS WHERE MY
ANSWER IS GOING TO GO.

She draws a line under the addition and syas
LET'S START WITH
THE ONES COLUMN.
SO I HAVE EIGHT PLUS
NINE, WHICH IS SEVENTEEN.
WELL, I CAN'T PLACE TWO DIGITS
IN ONE PLACE VALUE COLUMN,
SO I'M GOING TO PUT THE SEVEN
HERE BECAUSE THAT IS IN
THE ONES PLACE, AND I'M
GOING TO CARRY THAT TEN
FROM THE SEVENTEEN OVER
TO MY TENS COLUMN.

She writes 7 under the line and adds a 1 above the 6.

She says SO I'M JUST GOING TO REPRESENT
THAT WITH THAT LITTLE ONE THERE,
WHICH ACTUALLY
REPRESENTS TEN.
NOW I'M GOING TO ADD UP
EACH ONE OF THE DIGITS
IN THE TENS COLUMN.
SO ONE PLUS SIX IS SEVEN, AND
SEVEN PLUS SEVEN IS FOURTEEN.
I'VE GOT ANOTHER DOUBLE
DIGIT SO I'M GOING TO PUT
THE FOUR OF THE FOURTEEN
HERE IN THE TENS COLUMN,
THEN I'M GOING TO CARRY OR
TAKE THE TEN FROM THE FOURTEEN
OVER TO THE HUNDREDS PLACE.

She adds a 1 above the 3 and continues
SO, AGAIN, I'M GOING
TO DO THE SAME THING.
I'M GOING TO ADD ALL THE
DIGITS THAT ARE NOW
IN THE HUNDREDS PLACE.
ONE PLUS THREE IS FOUR,
AND FOUR PLUS TWO IS SIX.
SO I'M GOING TO PUT
THIS DOWN HERE.
NOW I DON'T HAVE
ANYTHING ELSE TO ADD,
IT LOOKS LIKE I'VE
GOT MY FINAL SUM,
WHICH IS 647.
SO WHEN WE'RE ADDING LARGE
NUMBERS, AND WE HAVE NUMBERS
THAT ARE OVER TEN, WE HAVE
TO MAKE SURE WE CARRY THOSE
NUMBERS OVER TO THE
NEXT PLACE VALUE
UNTIL WE GET TO
THE FINAL SUM.
GOOD JOB, TVO KIDS.
GOOD LUCK WITH
YOUR ADDING.
