Question

david wrote about a class trip to a glassblowers workshop. he made seven mistakes when writing possessive nouns. look for the mistakes, and fix them. use the proofreading marks in the box. remember a possessive noun shows who or what owns or has something. our classs visit to ms. andersons glass workshop was really interesting. i especially enjoyed the glassblowing demonstration. it gave everyone a firsthand look at this artists amazing skills. the workshops furnace heated some glass until it melted. when the mixtures temperature was about 2000°f, ms. anderson briefly dipped a hollow iron blowpipe into it. a small amount of melted glass stuck to the blowpipes tip. ms. anderson then blew gently into the blowpipe. her breath forced the glass to bulge out and form a hollow bulb. with a few twists and turns, the glasses final shape appeared. it was now a beautiful vase. of all the crafts i have seen so far, handmade glass fascinates me the most. did you correct seven possessive nouns?

Explanation:

• "classs" should be "class's" (add an apostrophe to show possession of the visit by the class).
• "Andersons'" should be "Anderson's" (assuming it's Ms. Anderson's workshop, so add an apostrophe + s for a singular noun).
• "artists'" should be "artist's" (this refers to one artist's skills, so singular possessive).
• "workshops" should be "workshop's" (the furnace belongs to the workshop, singular possessive).
• "mixtures" should be "mixture's" (the temperature belongs to the mixture, singular possessive).
• "blowpipes" should be "blowpipe's" (the tip belongs to the blowpipe, singular possessive).
• "glass'es" should be "glass's" (the final shape belongs to the glass, singular possessive).

Answer:

1. "classs" → "class's"
2. "Andersons'" → "Anderson's"
3. "artists'" → "artist's"
4. "workshops" → "workshop's"
5. "mixtures" → "mixture's"
6. "blowpipes" → "blowpipe's"
7. "glass'es" → "glass's"
