Reading Passage
It was the day of the big class party at Lincoln Elementary. The students were working hard to finish their math projects before the celebration. Ms. Hill told them to crunch the numbers one last time. Kevin and Maya graphed it out on their poster to show how much lemonade they could sell.
Emily noticed something didn’t add up with the total, so she asked to double-check the answer. “We need to break it down,” she said. Luis smiled and said, “Let’s take it step by step.”
As the group worked, Jayden forgot to carry the one, and their final answer was off by a mile. Ms. Hill helped them round it off, and the problem made sense again.
Finally, they all counted on each other to get it done. Ms. Hill looked over and said, “Now it all adds up! Let’s get to that party.”
