Assad was looking out the window of his Kindergarten classroom when he saw a big truck pull up outside. He watched as a woman wearing a hard hat and a bright orange vest got out of the truck and walked over to the school. Her name was Patty and she was a paver.

Patty walked into the classroom and introduced herself to Assad and his classmates. "Hi everyone, my name is Patty and I'm part of a construction crew that's here to build a bridge over the river at your school," she said.

Assad and his classmates were excited to hear about the new bridge. "Wow, that's so cool!" he exclaimed.

Patty smiled and continued, "But building a bridge is not easy. We need to figure out how to make it strong enough to hold everyone who wants to cross it. That's where engineering comes in."

Assad's teacher, Mrs. Johnson, chimed in, "Engineering is about finding solutions to problems. You need to use your brain to come up with ideas and then test them to see if they work."

Patty nodded, "Exactly! And that's why we're going to work together to build the best bridge we can."

Assad and his classmates were excited to help out. They couldn't wait to see what kind of bridge Patty and her crew would build.

Patty and her crew got to work right away, measuring the distance across the river and deciding how long the bridge needed to be. They brought in piles of wood and metal beams, hammers and nails, and all sorts of tools.

Assad watched as they worked, amazed at how quickly they were able to put everything together. But then, as they neared the end of the construction, they ran into a problem.

One of the metal beams they had used for the base of the bridge was not straight, and so the bridge was lopsided. "Oh no, what are we going to do?" cried Patty. "We can't have a bridge that leans to one side like this."

Assad could see that Patty was upset and he wanted to help. "Maybe we can use another beam," he suggested.

Patty thought for a moment and then exclaimed, "You're right! We can swap this beam out for another one and then the bridge will be level again."

They quickly found a new metal beam and swapped it out for the crooked one. The bridge was now level, but there was something else they hadn't noticed. One of the wooden planks used for the bridge had a tiny crack on it.

Patty and her crew didn't realize that the wooden plank had a crack in it until they were finished building the bridge. Assad noticed it immediately and pointed it out to Patty.

Patty inspected the plank closely and realized that it was too risky to use. "We need to replace this plank before someone crosses the bridge and it breaks," she said.

But they didn't have any more of that kind of wood, and the hardware store was closed for the day. "What are we going to do?" asked Mrs. Johnson.

Patty thought hard. "I know what we can do," she said. "We can use another type of wood that's stronger and safer. It might not match the other planks, but it's better to be safe than sorry."

They found a piece of stronger wood and replaced the cracked plank. The new plank didn't match the others, but the bridge was strong and safe.

When the bridge was finally finished, everyone gathered around to admire it. Patty and her crew had built a beautiful bridge that was safe and strong.

Assad and his classmates were proud that they had helped Patty and her crew build the bridge. They had learned so much about engineering and problem-solving, and they knew that they could use those skills in their own lives too.

As they crossed the bridge, Mrs. Johnson reminded them of the moral of the story. "Remember, always tell the truth because a liar won't be trusted," she said. "And always remember to use your brain to solve problems, just like Patty and her crew did today."

Assad smiled and felt happy knowing that he had been a part of building something important. He knew that he had learned a lot from Patty and her crew, and that he would always remember the lessons he had learned that day.
