[bright music] - All right, so right now, I have my friend... - Eva Luna.

- Eva Luna.

And we're gonna play Number Flash.

All right, so, today, I'm going to put a number of plant counters on here, I'm gonna flash it to you, and you have to see if you can show me the same amount, all right?

Are you ready?

All right, so I'm gonna show the camera, and then I'm gonna show you.

[bell dings] [upbeat music] - Five.

- Five, how did you know it was five?

'Cause you know, because how many are on the top?

How many squares are on the top row?

- Five.

- How many?

- Five.

- Five.

So, this is what I showed her, and she knew that the top row automatically had five, so she didn't even have to count.

Can you show them?

Do they match?

- Yes.

- Yes.

Great job.

All right, let's do another one.

Ready?

No peeking.

Ready?

[bell dings] - Four.

- Oh my goodness.

She knew right away it was four.

You're really good at this game.

Do they match?

- Yeah.

- Yes, and you knew that... How many are on the top all together?

- Five.

- Five, but there's one less, which makes... One, two.

- Three, four.

- Right, so five minus one we know is four.

Good job.

[bell dings] - Three.

- Oh, that was so fast.

Ready?

I did it fast.

[bell dings] - Six.

- How did you know that was six?

- 'Cause I saw it.

- 'Cause you saw it.

How many are on the top?

- Five.

- And how many are on the bottom?

- One.

- One, so we know that five and one more makes six.

Eva Luna's really good at this.

Let's see.

Do they match, friends?

- Yeah.

- Yeah.

All right, ready?

[bell dings] - Eight.

- Oh my goodness!

All right, let's see if I can get you.

Think I can get you?

All right, ready, friends?

[bell dings] - 10.

- Ah!

I'm gonna show my friends.

[bell dings] - Nine.

- My goodness, you are so good.

Let's see.

This is what I showed her, friends.

[upbeat music continues] Let's see if they match.

All right, friends, do they match?

- Yeah.

- Ready?

[bell dings] How many did I show you?

- Two.

- Two.

Oh my goodness, so fast.

I'm gonna try to do a super fast one.

Ready?

Ready?

[bell dings] - One.

- Ah, I was trying to trick you!

Let me see.

Show our friends.

They match.

I'm gonna show my friends.

I'm gonna show you.

How many is that?

- Seven.

- I can't trick her.

What if I do it this way?

[bell dings] Ready?

What is that?

- Six.

- Say it louder.

- Six.

- Six.

They match, friends?

- Yeah.

- Yeah, wow.

Okay.

I'm gonna try something new.

Ready?

All right, clear your board.

Let's see if I can get her on this one.

If I can't get her on this one, she must be an expert.

[bell dings] - [chuckles] Eight.

- Oh my goodness!

How did you know it was eight?

It was different!

How many are on the bottom?

- Five.

- And how many are on the top?

- Three.

- All right, show me.

I thought I was really gonna get Eva Luna there.

I tried to trick her by having five on the bottom and three on the top, and she still got it.

I changed the direction of where I'm putting them.

Show our friends what you have.

Do they match?

- Yeah.

- They do.

Great job.

So I just tried tricking Eva Luna in all these different ways, but her subitizing skills are so good.

Eva Luna, thanks for playing with us.

All right, friends, have a great day.

- Bye.

- Bye.
