Builders know what to do by using special plans called blueprints. These blueprints are like big maps that show builders how to make houses and buildings.
First, the builders look at the blueprints to see what they need to build. They check how big the walls are, where the doors go, and how many windows there should be.
Then, they get their tools like hammers, saws, and drills. They also use materials like wood, bricks, and cement.
As they build, they always check the blueprints to make sure everything is right. It’s like following a recipe when you make your favorite snack!
So, by looking at their special plans and using their tools, builders know just what to do to make buildings strong and safe!
