Midrash is a Jewish way of telling stories and explaining what things in the Torah mean. It's kind of like a treasure hunt where we look for hidden meanings in the words of the Bible.
Imagine you have a big puzzle with lots of pieces. Each piece is important because it helps you see the big picture. In the same way, the Torah has a lot of pieces and we use midrash to help us put them together.
Sometimes the stories in the Torah are hard to understand. Midrash helps us make sense of the stories by telling us what might have happened before or after the events in the Torah. It's like telling a story to help explain a story.
For example, in the Torah, it says that Noah built an ark to save his family and the animals from a big flood. Midrash might add details about how Noah was very brave and worked really hard to build the ark, even when other people made fun of him.
Midrash is kind of like a game where we all get to be detectives and try to figure out what the Torah is telling us. It helps us understand our history and our faith.
