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

A chart appears on the large touchscreen. The columns read "Hundreds, tens, ones, decimal, tenths, hundredths, thousandths."

Robyn says HI, TVOKIDS.
I'M TEACHER ROBYN.
I'M GOING TO SHOW YOU
A REALLY EASY TRICK
FOR MULTIPLYING THREE-DIGIT
NUMBERS BY POWERS OF TEN.
AND TODAY I'LL SHOW
YOU TEN, A HUNDRED
AND A THOUSAND.
THE THREE-DIGIT NUMBER
I'LL CHOOSE IS
TWO-HUNDRED AND
SEVENTY-FIVE.

She writes 2 under hundreds, 7 under tens and 5 under ones.

She says LET'S TRY MULTIPLYING
IT BY TEN.
NOW I SEE THAT TEN
HAS ONLY ONE ZERO.
SO I'M GOING TO
TAKE THE ZERO,
PUT IT IN THE ONES'
COLUMN AND THEN BUMP OVER
MY TWO-HUNDRED AND
SEVENTY-FIVE
TO MATCH UP.

She writes 2 in thousands, 7 in hundreds, 5 in tens and 0 in ones.

She says SO, TWO-HUNDRED AND
SEVENTY-FIVE TIMES TEN
IS TWO-THOUSAND
SEVEN-HUNDRED AND FIFTY.
THE SAME TRICK APPLIES
WITH A HUNDRED.
NOW I HAVE TWO ZEROS.
SO, AGAIN, I'LL
START IN THE ONES
AND NOW I'LL BRING IN
MY TWO SEVENTY-FIVE.

She writes 2 in ten thousands, 7 in thousands, 5 in hundreds, 0 in tens and 0 in ones.

She says SO, TWO SEVENTY-FIVE
TIMES A HUNDRED
IS TWENTY-SEVEN THOUSAND
FIVE-HUNDRED.
I THINK YOU KNOW WHAT
I'M GOING TO DO
WITH THE THOUSAND.
YEP, I SEE THREE ZEROS,
THREE ZEROS STARTING
IN THE ONES.

She repeats the process adding three zeroes, so the final number is 275000.

She says THEN I'LL BRING OVER MY
TWO SEVENTY-FIVE.
TWO-HUNDRED AND SEVENTY-FIVE
MULTIPLIED BY A THOUSAND
IS TWO-HUNDRED AND
SEVENTY-FIVE THOUSAND.
REMEMBER THIS TRICK
AND MULTIPLYING
BY POWERS OF TEN
WILL BE EASY.
GOOD LUCK.
