Relative Pronouns are addressed in the Language CCSS 4.1.A.
My students really struggled with when to use who versus whom. I taught them the he (who) versus him (whom) rule.
Included in this set are Anchor Charts for when to use Who versus Whom, also a student note sheet, and a practice sheet with an answer key.
Hopefully your students will find this helpful like mine did! Please take time to leave feedback, and like and pin this product!
