Troy stands next to a gray chalkboard showing math signs, different coins and colourful logo that reads "TVOKids Home Work Zone." He is in her early thirties, clean-shaven and bald. He wears a blue T-shirt and a watch.

Holding a meter sitck, he says HEY GUYS, IT'S
TEACHER TROY HERE TO HELP YOU
WITH MEASURING LENGTHS.
WHEN WE TALK ABOUT MEASURING
LENGTHS, WE USUALLY TALK ABOUT
USING RULERS AND WE TALK ABOUT
UNITS OF MEASURE, SUCH AS THE
METRE, THE CENTIMETRE, THE
MILLIMETRE.
TODAY WE'RE GOING TO TALK ABOUT
METRES AND CENTIMETRES.
IF YOU LOOK AT THIS, THIS IS
WHAT'S CALLED A METRE STICK THAT
I'M HOLDING UP IN FRONT OF YOU.
A METRE STICK IS ACTUALLY 100
CENTIMETRES AND IF YOU LOOK AT
IT, A CENTIMETRE IS ONE OF THESE
VERY, VERY SMALL DIVISIONS.
SO, IF YOU TOOK THE END OF THE
RULER TO THIS FIRST LINE HERE,
SO ALMOST THE WIDTH OF MY
FINGER, A LITTLE LESS, THAT
GIVES YOU ONE CENTIMETRE.
SO, IF YOU LOOK AT IT AND YOU
KEEP COUNTING 2, 3, 4, 5, 6, 7,
8, 9, 10 AND IT KEEPS GOING, 100
OF THOSE WILL GIVE YOU THE FULL
METRE STICK OR ONE METRE.
WHEN YOU MEASURE THINGS, YOU
WANNA MEASURE THINGS THAT ARE
SMALL USING CENTIMETRES OR
MILLIMETRES.
WHEN YOU'RE GETTING INTO
MEASURING THINGS THAT ARE LARGE,
WE START TALKING ABOUT THINGS
LIKE METRES AND EVEN LIKE,
THINGS LIKE KILOMETRES.
SO, IF YOU HAVE TO WALK TO THE
LOCAL STORE WHICH IS PROBABLY A
KILOMETRE AWAY, THAT'S 1,000
METRES.
SO, REALLY IMPORTANT, JUST TO
GET BACK TO IT AND GIVE YOU A
BRIEF EXPLANATION.
WE HAVE ONE CENTIMETRE AND ONE
METRE AND ONE METRE IS EQUAL TO
100 CENTIMETRES.

Using chalk, he writes down the measures mentioned and continues SO, IT'S BASICALLY THE SAME
RELATIONSHIP THAT YOU HAVE
BETWEEN A PENNY AND A DOLLAR.
THERE'S 100 PENNIES WILL GIVE
YOU 1 DOLLAR, 100 CENTIMETRES
WILL GIVE YOU A METRE.
SO, FOR EXAMPLE, I'M ALMOST TWO
METRES TALL.
SO, I'M BASICALLY 100 AND ALMOST
85 CENTIMETRES, JUST TO GIVE YOU
AN IDEA OF HOW THE UNITS DIFFER.
SO, WHEN YOU'RE MEASURING THINGS
THAT ARE BIGGER SIZE, YOU WANNA
USE METRES.
WHEN YOU'RE MEASURING THINGS
THAT ARE REALLY SMALL, YOU'RE
GONNA WANNA USE CENTIMETRES OR
THINGS THAT ARE REALLY, REALLY
SMALL, LIKE INSECTS, THEN YOU'RE
GONNA GET INTO THINGS THAT ARE
CALLED MILLIMETRES.
I'M TEACHER TROY AND I HOPE THAT
HELPS.
