Reading Passage
It was the day of the big school clean-up, and everyone was ready. The gym was a jungle of equipment and boxes. Mia looked at the mountain of chairs stacked in the corner. “This is going to take forever,” she said. Mr. Lewis smiled and pointed to the sea of helpers around them.
Liam was already dragging a train of carts filled with decorations. “Let’s move this tower of mats first,” he said. They worked hard, but every time they cleared a space, it felt like a floodgate of more stuff opened. By lunchtime, Mia flopped down beside a wall of trash bags.
“We’ve made a field of progress,” she joked, wiping her forehead. Just then, a loud noise came from the hallway it was a roar of laughter from another class finishing early. “We’re almost done!” Liam cheered. The last boxes were a beast of a job, but they did it. The gym looked great.
