- We are multiplying by seven, today in the math park.

- Get ready for a very special, super duper math class.

We're going on a field trip, where learning math is tons of fun.

Our destination is the Math Park.

With our friends Ranger Riff, Ashley, Charles, Mike, Janet, Kiffin and Math Dylan.

- Hello, chipmunks.

Welcome to Math Park.

I'm Parker Ranger A. Rith Metic, but you can call me Ranger Riff.

Math Park is the place where trees are shady characters, leaves are fall guys and math is always fun.

We're going to have a grand time.

Today we're going to learn multiplying by seven.

- We're multiplying by seven and you don't have that many new facts to learn.

Let's go over the old stuff first.

- 7 x 1 = 7 and 1 x 7 = 7.

7 x 2 = 14 and 2 x 7 = 14.

7 x 3 = 21 and 3 x 7 = 21.

7 x 4 = 28 and 4 x 7 = 28.

7 x 5 = 35.

5 x 7 = 35.

7 x 6 = 42 and 6 x 7 = 42 and 7 x 10 = 70 and 10 x 7 = 70.

- So now let's go over to the Multiplication Station and practice these facts again.

But this time they will not be in the same order.

Think you can do it?

Let's find out.

- [Piano Music playing] - And now the new stuff.

We only have three facts to learn.

7 x 7 = 49.

8 x 7 = 56 and 9 x 7 = 63.

You've learned a lot.

- Now let's go back to the Multiplication Station and practice the new stuff.

[Vacuum Cleaner Whining] - Hey Roberto, let's play some multiplication coverup.

- Yeah, sounds good.

Let me raise the board.

- Okay.

Yeah.

Okay.

Let's listen to the rules again.

- Sure.

- The object of the game is to cover four squares in a row.

You can cover them horizontally, vertically, or diagonally.

To cover a product, you must say the multiplication fact that goes with the product.

Punch the buttons on your remote control to cover the product you want.

- Okay.

How about if I'm green?

- Yeah, I'll be red.

- Sounds good.

- And I'll start - Please.

- 5 x 7 = 35.

Cover.

- 2 x 7 = 14.

Cover.

- 4 x 7 = 28.

Cover.

- 4 x 7 = 28.

- 9 x 7 = 63.

Cover.

- 8 x 7 = 56.

Cover.

- 3 x 7 = 21.

- 1 x 7 = 7 seven.

Cover.

- 3 x 7 = 1.

Cover.

- 9 x 7 = 63.

Cover.

- 10 x 7 = 70.

Cover.

- 1 x 7 = 7.

Cover.

- 7 x 7 = 49.

Cover.

- 8 x 7 = 56.

Cover.

- 6 x 7 = 42.

Cover.

Four in a row.

I love it.

Roberto, man, you did a good job.

I just did a little better this time.

- You did.

Good job.

- Can you say the product to the next multiplication fact you see before the surfer dude does.

[Clock Ticking] - 42.

- Howdy, Sidewinders.

I'm Math Dylan.

And we're going to have a little contest today to see who can multiply faster.

The way this works is you're going to grab a pen and a paper and when that multiplication factor appears on the screen, we're going to see who can write the product faster.

But wait, till it appears and then I'll say, draw.

Get ready, get set, Draw.

Done.

If you got 49, then you are correct.

Why, you're sharper than a box of bowling balls.

And I'm going to get you next time.

[Country Music Playing] - Mm, Bananas.

I love bananas.

They're my favorite fruit and there are seven groups of two.

7 x 2 = 14.

14 bananas.

I could eat 14 bananas about right now.

[Horse Neighs] Listen to those horses.

There are two groups of seven.

2 x 7 = 14.

14 horses.

Look at that.

7 x 2 = 14.

T2 x 7 = 14.

Multiplication is something else.

- It's time to head over to the Multiplication Station, where Max, the Multiplier is multiplying by seven.

- From the Fun Factor Satellite in outer space and the proud Product Studios in Hollywood.

You are watching the Multiplication Station.

- Hey, this is your Multiplication Station VJ, Max, the Multiplier.

Today, we are multiplying by seven.

Are you ready for the Multiplication Station Quicky Quiz?

Let's find out.

- The Multiplication Station presents the Quicky Quiz.

- Wonderful!

- See if you can say the products before Charles does.

- How'd you do?

You know, if you missed some, you can go back and practice with the video again.

With a little practice, you become a multiplication sensation.

- And now it's time to wipe out the multiplication facts we learned today.

Let's wipe out multiplying with seven.

- And now it's time for the Multiplication Wipeout.

If you learned the multiplying by seven facts, you get to wipe them out.

There aren't many left, but here we go.

Here are the eights.

Wipe out 7 x 8.

And here are the nines.

Wipe out 7 x 9.

Next time we will be multiplying by eight.

I can't wait to wipe those out.

[Horn Blows] - Did you hear that?

That means Math Park is closing for today.

Until Math Park reopens, I salute you Math Chipmunks.
