Read the clauses. Then write main or subordinate for each clause. if the clause is a subordinate clause add a main clause to make it a complex sentence

Great! All are right.
Nice job! Here's an explanation for each clause:
1. "Before I go to school" - subordinate clause; To make it a complex sentence, add a main clause: "Before I go to school, I take a shower."
2. "We heard a concert at Town Lake Park" - main clause; It does not need any additional clauses.
3. "That I read for English class" - subordinate clause; To make it a complex sentence, add a main clause: "I finished the book that I read for English class."
4. "The principal's office is at the front of the school" - main clause; It does not need any additional clauses.
5. "Although the team played well" - subordinate clause; To make it a complex sentence, add a main clause: "Although the team played well, we lost by two points."
Remember, a main clause can stand alone as a complete sentence, while a subordinate clause cannot.
