Apostrophe Omission and Possession

The last time I saw Dr. Jones, he was at the nurses station. 

The punctuation mark used to indicate either possession or the omission of letters or numbers.

• comma

• semicolon

• quotation mark

• apostrophe

The sentence below in red is incorrect. It is missing a singular possessive apostrophe. The subject noun, teacher, does NOT need to be made plural. Where should the possessive apostrophe go in the sentence below? The teachers computer is brand new.

• The teacher' computer is brand new.

• The teacher's computer is brand new.

• The teachers' computer is brand new.

Revise the sentence below by adding the possessive apostrophe + s to the correct location. *(Fix the sentence by rewriting it correctly. = revise) The teacher computer is brand new.

What are the two correct ways to edit the incorrect sentence below?

• Mrs. Collins's staplers' are on the desk.

• Both of these are correct: Mrs. Collins's stapler is on the desk. or Mrs. Collins stapler is on the desk.

• Mrs. Collins' stapler is on the desk.

• Both of these are correct: Mrs. Collins's stapler is on the desk. or Mrs. Collins' stapler is on the desk.

Revise the incorrect sentence in the paragraph below. The last sentence in red that is underlined and italicized is the only one that is incorrect. Retype it and add the possessive form to the correct location.

Current GUHSD students have access to technology to a much greater degree than Mr. Rabat and Mrs. Collins ever had as students. Every single student can borrow a computer for free. One day, the computers will need to be updated. The student computers are a year old currently.

(Again, retype and correct only this sentence: The student computers are a year old currently.)
