Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
A school has 1000 students. Half of the students were taken on a trip to the nearby beach. Half of the remaining students were sent home. How many students are still in the school?

### Response:
1000/2= <<1000/2=500>>500 students were taken on a trip to the nearby beach.
So 1000-500 = <<1000-500=500>>500 students were not taken to the beach.
Half of the students who were not taken to the beach, 500/2 = <<500/2=250>>250, were sent home.
The total number of students who are still in the school is 250.
