Expertise is like being a superhero in something you love to do. Imagine you have a special power to draw the best pictures. You know all the colors and shapes, and you can make your drawings come to life. That’s because you’ve practiced a lot and learned all the secrets of drawing. Just like a superhero who knows how to save the day, you know how to make amazing art.

Think of expertise as building a tall tower with blocks. At first, you start with just a few blocks, and your tower is small. But as you keep adding more blocks, your tower gets taller and stronger. Each block is like a piece of knowledge or a skill that you learn. The more you practice and learn, the taller your tower becomes, and soon you have the tallest tower in the room!

Another way to think about expertise is like baking a delicious cake. At first, you might not know all the ingredients or how long to bake it. But after baking many cakes, you remember the recipe by heart and can make the yummiest cake without even looking! That’s because you have expertise in baking.
