A secret that will change the way he looks at the world forever!

Our story begins with Mojo, a friendly monster who loved school, especially math.

Until one day, when something terrible happened. The math problems got harder.

Nothing made sense anymore!

Mojo had a devastating thought.

He just wasn't smart enough for school.

It seemed the only reasonable thing to do was pack his things and leave forever.

Just then, he heard his friend, Katie, laughing.

"Mojo, you can't just give up," she said.

"I have no choice, Katie!" said Mojo. "You're either born smart, or you're not."

"And I realized today that I'm not."

"Mojo, that's not how it works," said Katie.

"Anyone can be smart, you just have to work at it."

"Pssh, that's the most ridiculous thing I've ever heard," said Mojo.

"It's not ridiculous, it's science," said Katie. "Neuroscientists studied the brain

for years and discovered an incredible secret: that your brain is like a muscle!

"When you try challenging things, like those hard math problems, you're giving your brain

the exercise it needs to get stronger, which make you smarter!"

"Oh! Is that really true?" said Mojo.

"Of course," said Katie.

"It's like how when you were a baby: you didn't know how to talk."

"But you kept trying, exercising your brain, until one day, you could!"

Mojo couldn't believe what he was hearing.

If your brain was really like a muscle,

Did that mean anyone could become smarter? Even him?

He turned to ask Katie, but just then, she had to be off to her next class.

But maybe you can answer Mojo's question.

What do you think? Can Mojo become smarter?

What about you?

Hmm, now that's an interesting question indeed!
