Tala grabs her backpack after school and walks home. When she opens it to start homework, nothing inside looks familiar. This is not her backpack at all.
Tala walked home from school, her backpack feeling a little heavier than usual on her shoulders. She didn’t think much about it until she sat down at her kitchen table and unzipped it to start her homework.
Inside, nothing looked right. Instead of her math book, there was a book about dinosaurs. Instead of her blue pencil case, there was a green one filled with colored markers.
“This isn’t my backpack!” Tala said out loud, surprised.
She looked closely at the outside. It was the exact same color and style as hers, dark blue with a small star on the front pocket. No wonder she hadn’t noticed the mix-up right away.

“There must be another backpack just like mine at school,” Tala said to her mom. “I need to find out whose this is.”
She searched carefully through the mystery backpack for any clues. Near the bottom, she found a folded piece of paper with a name written in careful handwriting: Omar.
“Omar,” Tala said thoughtfully. “I don’t know an Omar in my class. He must be in a different class.”
The next morning, Tala brought the backpack to school and asked her teacher for help. Her teacher smiled. “I think I know exactly who that belongs to,” she said. “Omar is in the class next door. He mentioned yesterday that his backpack looked different somehow.”

Tala walked to the classroom next door and knocked politely. A boy about her age looked up, his eyes widening when he saw the blue backpack with the star on it.
“That’s my backpack!” Omar said. “I couldn’t figure out why my dinosaur book was missing yesterday. I must have taken yours instead!”
“I have a matching one,” Tala said, laughing. “I didn’t notice until I got home and found a dinosaur book instead of my math homework.”
They quickly swapped backpacks, both relieved to have their own things back.
“Thanks for figuring it out,” Omar said. “I was starting to think I’d lost my dinosaur book forever.”
“No problem,” Tala said. “Mystery solved.”
From then on, Tala tied a small red ribbon to her backpack’s zipper, just to make sure this particular mix-up never happened again.
