Leo’s alarm clock let out a persistent beep-beep-beep at seven o’clock sharp. Usually, Leo loved the sound of the morning, but today was different. It was the first Monday of September, which meant it was the first day of third grade at Oak Creek Elementary. He pulled the covers over his head, wishing he could stay in his cozy bed forever. Summer had been filled with swimming pools, ice cream cones, and late nights watching movies. Now, everything was about to change.

His mother knocked gently on the door. "Time to get up, Leo! You don't want to be late for the big day." Leo sighed and climbed out of bed. He put on his favorite striped shirt and his brand-new sneakers. When he looked in the mirror, his face looked a little pale. He felt like a swarm of tiny butterflies was fluttering around inside his stomach. This was a feeling he got every year, but this year felt bigger. Third grade meant longer books, harder math, and a brand-new hallway in the school building.

During the walk to school, Leo clutched the straps of his backpack tightly. The morning air was crisp, and the leaves on the maple trees were just starting to turn a pale shade of yellow. He saw his neighbor, Sam, running ahead with a group of friends. Sam was in fifth grade and seemed to have no fear at all. Leo wondered if he would ever feel that confident.

When they reached the school gates, the playground was a whirlwind of activity. Children were laughing, parents were taking photos, and teachers were holding colorful signs. Leo spotted the sign for Room 12. His teacher’s name, Mrs. Gable, was written in bright purple letters. He took a deep breath and kissed his mom goodbye.

"You’re going to have a wonderful day," she whispered, giving his hand a reassuring squeeze. Leo walked down the long, shiny hallway until he found Room 12. The door was covered in giant paper sunflowers. In the center of each flower was a student's name. He scanned the yellow petals until he found "Leo." He stepped inside, and the familiar scent of school—a mix of whiteboard markers and floor wax—filled his nose.

The classroom was bright and organized. There were tall bookshelves filled with colorful spines and a large rug in the corner with a map of the world on it. "Hello there! You must be Leo," a warm voice said. Leo looked up to see Mrs. Gable. She wasn't nearly as tall as he had imagined, and she had a kind, crinkly smile. She wore a cardigan with tiny embroidered apples on the pockets. "Your desk is right over there, next to the window."

Leo walked to his desk and saw a girl already sitting in the chair next to his. She had bright green glasses and two bouncy pigtails. "Hi! I'm Maya," she said enthusiastically. "I was in Mrs. Gable’s class for summer reading, and she is the best. Do you like dinosaurs? I brought my favorite plastic triceratops for show-and-tell."

Leo felt a little bit of the tension leave his shoulders. "I'm Leo. I don't have a dinosaur, but I have a dog named Buster who acts like a T-Rex sometimes." Maya laughed, and the sound made Leo smile for the first time all morning. As the rest of the students filed in, Mrs. Gable gathered everyone on the large map rug. Instead of starting with a difficult lesson, she told a funny story about her own first day of school when she accidentally wore two different shoes. The whole class giggled, and Leo realized he wasn't the only one who had been nervous.

The morning flew by. They played a game to learn everyone’s names and started an art project called "The Map of Me." Leo drew his house, his soccer ball, and a giant pepperoni pizza. He was so focused on his drawing that he didn't even notice when the clock moved toward lunchtime. By the time the final bell rang at the end of the day, Leo’s stomach felt perfectly still. The butterflies were gone. As he spotted his mom waiting by the gate, he realized that while summer was great, third grade was going to be an even better adventure.
