All right, who should I call on?
Kate. Please come up to the board.
I can definitely solve these!
I’ll just carry the three down here.
And the four moves up here.
And I finish with the nine, all the way down.
Oh, uh, yes. Take your seat, please.
What just happened?
Gosh. I’m hungry.
Time to break out my secret snack!
Huh? It’s empty! I must have already eaten it.
All I’ve got are wrappers.
Well darn. Now what?
The candy safe! Of course!
That’s where teacher has been stashing all our confiscated candy.
I know she took some good stuff from me.
NO!
If I could just break into the safe, I can take it all back!
All right. Time to be like Ocean’s Eleven.
Okay. Now to break open this safe.
Shoot! I don’t know the code!
They make it seem so easy in the movies.
No way! She’s got the password right here!
Well, if I can do the math, anyway.
Ugh. Why am I so bad at math?
I don’t think I can count this on my fingers.
Wait! Doy. I have my phone!
Except I forgot to charge it.
Kate! What are you doing over there?
Oh, I thought you were the teacher. Come help me.
Oh! The candy safe! I got it! Easy!
Okay watch this.
First let me copy down the equation.
I’ll draw a line here. Then add a plus and the first six.
I’ll do the same on the other side.
Now I’ll solve this first side. 650.
And then solve the second side.
That gives you 240.
And the round numbers are much easier to add.
We have 890 as a total.
Now we’ll go back up and add the 6 and 2.
And then we’re going to subtract the 8 from the 890.
That gives us 882. Our final answer!
That’s it! That’s the safe code!
Amazing! You’re so good at math!
Time to get our candy back.
It worked! It’s full of candy!
What is going on up there?!
Oh no! She’s back!
We were just really hungry…
All right, let me show you how to solve this.
This is sooo boring.
I better write this down in case it’s on the test.
Are you following me? Okay, so next steps.
Ah! It’s just too much!
Why is she making this so hard?
Seriously? No way!
Kate? What’s so funny?
There’s a much easier way to do this.
Watch. I’ll show you this hack.
It’s 80 percent, so we’ll take the 8.
Of ninety, so we’ll multiply it with the nine.
That gives us 72. Which is the same as the answer.
Are you kidding me? It’s that simple?
Wow! That’s so much easier!
I’ll just cross out all these notes.
And then just write it down like Kate showed us.
Phew. What a huge relief.
Oh! There’s the bell!
I need the eraser.
Oh no. I’ve been caught!
Gotta play it smooth.
Hold it right there, Madison!
Since you like to draw on the board, you can solve this equation.
Ooooh… I’m not sure…
Psst! Kate! Help me out!
Don’t ask me! I don’t know!
Really girls? Come here, let me show you.
Just use your fingers. The ones you drew, I mean.
We have 6, 7, 8, 9, and 10 on each finger.
Now, where’s the 7? Right here.
And the eight is this finger.
Now, fill in all the lower numbers, too.
We’ve got 5 fingers total.
So, we write the five up here.
And then what about the fingers that are remaining?
Three on this hand and two on this one.
Multiply those together and we get 6.
And that’s the answer!
Wow. I didn’t know our fingers could do so much!
Well, I am a teacher. Now take your seat.
Oh! I’m so nervous about this test!
Really? I think it’s gonna be easy!
I don’t even know where to start…
Okay, she’s not looking. Now’s my chance.
Calculator, you are going to save me.
Is she using a calculator?!
Madison. I can see you.
Oh, sorry. I’ll put it away.
How am I going to solve these?
Maybe it’s something like this…?
No. This isn’t right at all.
What does Kate have for the answer?
No way! She’s done already!
What’s that on her paper? Doodles?
Kate. What are those butterflies?
Here. I’ll show you.
Here are the fractions.
Now I’ll draw kitty corner circles on both sides.
And then turn it into a butterfly.
Next, multiply the corners.
And put the answer by the antennae.
Don’t forget to do both corners.
The next step is multiplying the bottom row.
Then subtract the antennae numbers.
That’s your top number, and you already have the bottom number.
There you go!
Wow! It’s useful and pretty!
I’m done! Let’s turn in our tests.
I do love a math test.
This will be super easy, of course.
I’ll just diagram my answers.
It never hurts to show your work.
And first question, solved!
What? How is she done already? And no diagrams!
How did you do that?
Teacher. Teacher!
Ugh. What, Madison?
Oh, Kate. You’re done?
Really? That was so fast! Good job!
Come on up here and let me see your answers.
Of course. Here I come.
Now, let’s see…
You got them all correct! You earned an A plus!
Oooh. That makes me so mad!
I bet she cheated somehow.
Madison, don’t be like that. Let me show you.
Fine. But only because I like to learn.
Okay. Take the number and multiply it by 2.
Make sure to do each number.
That gives us 6244.
Now, we’ll add a decimal in the first spot.
And that’s the answer!
Wow. That’s veery impressive. Thank you for sharing your knowledge.
