Re: Possessive adjectives VS. Personal pronouns
Welcome to the forum, MastersSara.
You'll find the labelling here rather confusing, as there is no general agreement. Depending on where you look, 'my', for example, may be described as a possessive, possessive adjective, determiner, possessive determiner or even possessive pronoun.
Are you using a coursebook or particular grammar or dictionary with your classes? If so, go with the labels used there. Unless you are working with a syllabus that insists on learners being able to label parts of speech, there is no need for you to go into great detail.
My own suggestion (others may disagree), if you have no set books, is that it does no harm to label those words that stand in place of a noun as pronouns: I, me (the speaker), we, us (the speaker and one or more others), you (the person/people spoken to), it, they, them (the person/people or thing[s] spoken about). Label those words that denote possession in some form possessives: my, mine, your, yours, his, her, hers, its, our, ours, their, theirs.
