What is the grammatical form and function of "bored with...grammar lessons" and "the class clown"?

Bored with their teacher's grammar lesson is a participle clause. The implicit subject is 'the students' (the subject of the main clause). The implicit tense is the past (the tense in the main clause, laughed). The implicit relationship is cause: Because the students were bored with the lesson.

Most classes have one student who, more than others, refuses to take learning seriously and makes jokes and acts silly during class time. This student is called "the class clown". It turns out that in the story you're reading, Bobby is the class clown. This is expressed grammatically as an appositive construction.
