How do you know if the pronoun agrees with it's antecedent. I am not sure what antecendent really means

An antecedent is the noun to which the pronoun is referring.

Jill painted her cousin's room yellow.
(The pronoun "her" is referring to "Jill" -- "Jill" is the antecedent for "her.")

Additionally --

If an antecedent is singular, then the pronoun needs to be singular, too, as in the Jill/her example I gave you above.

If an antecedent is plural, then the pronoun needs to be plural, too:
The students need to have their textbooks with them during each class.
(The pronoun "their" refers to "students" -- both are plural.)

The antecedent is the word to which the pronoun refers. In these examples, the pronoun is in italics and the antecedent is in bold.

Marilyn drank her glass of water in one gulp.

The boys gave their opinions about the new coach.

Mr. and Mrs. Standard bought the big house on the corner, and they plan to move in Saturday.

Pronouns must be of the same gender (male or female) and the same number (singular or plural) as their antecedent.
