could someone translate this into words that a teenager would use?
All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had. 33 With great power the apostles continued to testify to the resurrection of the Lord Jesus. And God’s grace was so powerfully at work in them all 34 that there were no needy persons among them. For from time to time those who owned land or houses sold them, brought the money from the sales 35 and put it at the apostles’ feet, and it was distributed to anyone who had need.
I don't see any words that are not in a teen's vocabulary.
Take it one verse at a time. Example:
32. All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had.
The believers agreed and shared everything with each other.
I'm sure you can do the rest.
