Sure! Here’s a simple summary of Chapter 2 of Harry Potter and the Sorcerer’s Stone for 4th graders:

Chapter 2: The Vanishing Glass

Harry Potter lives with his mean relatives, the Dursleys. They don’t like Harry and treat him badly. One day, they take Harry to the zoo for Dudley’s birthday. While they’re there, Harry talks to a snake in its glass cage. Suddenly, the glass disappears, and the snake gets out! Everyone is shocked, but Harry doesn’t know how it happened.

Harry starts to realize that there might be something special about him, even though the Dursleys try to keep him down.
