Colourful animated numbers with googly eyes jump around and form the name "Wacky Number Songs."

A song says IT'S THE WACKY WACKY
NUMBER SONGS.
OH YEAH.

Ava stands in a nice bedroom filled with furniture. She is around 12, with two long braids. She wears a striped yellow shirt under a denim overall.

In a big screen, Ava appears wearing animated wigs, hats and different clothing.

Ava says DO YOU HAVE SISTERS AND BROTHERS
AND COUSINS?
MAYBE AN UNCLE, AND AN AUNT, OR
A GRANDMA?
WELL, I HAVE A BIG FAMILY.
NUMBERS HAVE FAMILIES TOO.
THEY'RE CALLED FACT FAMILIES.
THE FACT FAMILY SHOWS THE
RELATIONSHIPS BETWEEN THE THREE
NUMBERS INVOLVED.
WE CAN EASILY CHECK OUR ANSWERS
BY REARRANGING OUR MATH
EXPRESSIONS.
IT'S A GREAT WAY TO SEE HOW THE
THESE NUMBERS RELATE TO EACH
OTHER.
SO LET'S STEP INTO THEIR HOUSE
AND SEE JUST HOW 2, 3 AND 5 ARE
RELATED.
HIT IT!

An animation shows numbers 2, 3 and 5 inside a house.

With a blond wig and a white hat, Ava sings ADD TWO NUMBERS TOGETHER AND
THE TOTAL DOES INCREASE.
SUBTRACT A BIGGER NUMBER FROM
THE FIRST AND YOU SEE IT
DECREASE.
BUT THESE NUMBERS LOOK LIKE
THEY COULD BE.
A GROUP OF FACTS IN A FACT
FAMILY.
ADD 2 AND 3, THEY EQUAL
5.
SWITCH THEM AROUND AND IT'S
STILL ALL RIGHT.
NOW IT'S TIME TO
FLIP THE FACTS.
TO SEE IF THE NUMBERS WILL
SUBTRACT.
TAKE NUMBER FIVE AND
PUT IT FIRST.
SUBTRACT TWO, YOU'LL SEE THIS
RELATION WORKS.
FLIP IT AGAIN AND SUBTRACT THE
THREE.
IT EQUALS TWO AS YOU CAN
SEE.
SIMPLY GREAT.
ONCE WE SEE HOW
THEY RELATE.
YOU CAN SEE THE SIMILARITY.
NUMBERS CAN MAKE UP A HAPPY
FACT FAMILY.

The song ends.

Ava says FACT FAMILIES HELP US ADD AND
SUBTRACT.
THE FACT FAMILY NUMBERS HELP
EACH OTHER, JUST LIKE MY FAMILY
HELPS ME!
(laughs)
AND THAT'S, A FACT!
