# Transcript: Adding Three Digit Numbers

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.
