Welcome to Crash, Course, Math!
-
Hey Brainiacs! What do we have here?
-
We’re going to have lots of fun today!
-
We’ve got small vehicles, medium vehicles and a
-
large vehicle!
-
Here’s a small Smart Car (beep, beep)
-
A medium monster truck (rev, rev)
-
A large haul truck – woah, look how big it is!
-
We’ve also got a medium fire truck
-
and a small bulldozer!
-
Check it out! We’ve got some great big bowling pins
-
set up in the street!
-
There are 10 pins, just like in a bowling alley.
-
We can use adding to quickly count them up.
-
This row has four,
-
and this row has three.
-
So four, plus three, equals seven.
-
There are three more so seven, plus three, equals ten!
-
There are ten bowling pins set up in the street.
-
Let’s see how many of these pins each vehicle can
-
knock down!
-
Can you guess which one will knock over the most pins?
-
Let’s start with the Smart Car.
-
OK little Smart Car, let’s see how many pins you
-
can knock down!
-
Ready? Go little Smart Car!
-
Awe, the little bitty Smart Car was too small to knock
-
down many of the pins. How many did he get?
-
That’s easy, we can just count them…1, 2.
-
The Smart Car knocked over 2 pins.
-
Let’s see how many pins the little bulldozer can get.
-
Go little bulldozer!
-
I bet he can knock down more than the little
-
smart car.
-
Not too bad! There are 5 pins left standing.
-
We know that we started with 10 pins so we can find
-
how many pins were knocked down by subtracting
-
five from ten.
-
Ten, minus five, equals five!
-
So the bulldozer knocked over 5 pins!
-
How many pins do you think the monster truck
-
will knock down?
-
Ready? Three, two, one...Go!
-
Looks like the monster truck knocked down even
-
more pins!
-
There are four pins remaining, so how many did he
-
knock down?
-
We started with ten pins, so if we subtract the pins
-
that are left, we’ll find the number that was
-
knocked down.
-
So ten, minus four, equals six.
-
The monster truck knocked down 6 pins.
-
Looks like he’s in the lead now.
-
Let’s give the fire truck a try. [Siren & horns]
-
Can you guess how many pins the fire truck will
-
knock down?
-
All set? Go fire truck!
-
Wow, good job! There are only 3 pins left standing!
-
So if we started with ten, and we have three left
-
standing, that means that ten, minus three,
-
equals seven pins knocked down!
-
That’s the most pins so far!
-
Now it’s time for the giant haul truck!
-
I bet it’s gonna knock down a lot of pins!
-
Ready? GO!
-
Here we go! Let's see how many we'll get!
-
StrrrIKE! The haul truck knocked down all of the pins!
-
So there are zero bowling pins left standing!
-
So ten pins, minus zero pins left standing, equals
-
ten pins knocked down!
-
We have a winner! [cheers]
-
The haul truck knocked down the most pins of
-
all the vehicles!
-
Did you guess right?....
