Justin was participating in this year's talent show. He has been working all year on his act.

Justin has mastered juggling with 3 balls. He knew he wouldn't be able to win by just juggling the 3. So he began to practice more!

Justin added 3 more balls. He was now juggling 6 balls. He knew he could keep on adding more and more.

Justin kept on practicing. Every place he went, he kept juggling. He was juggling while at school. 

While swimming in a pool.

Even while riding a mule!

Roof!

Justin added 6 more balls! How many does Justin have now?

Justin has 12 balls!

What is the dog doing?

While Justin was sleeping, his dog took 4 balls from his backpack. 

Justin had 12 balls and his dog took 4. How many balls does Justin have now?

When Justin woke, he put out his balls. He began to count 1,2,3,4,5,6,7,8. Justin only has 8 balls now.

Justin went to buy more balls to juggle. With the talent show just days away he was worried he would not win with 8 balls. At the toy store, he saw 4 balls in the window.
