Teaching Possessive Nouns in Three Days Is Easy - Free Printable

To solve this worksheet, we need to change phrases like "seeds of pumpkins" into possessive nouns like "pumpkin seeds".

Here is the step-by-step logic based on the rules provided in the image:
1. Identify the owner: Look at the second part of the phrase (after "of"). This is who owns the first thing.
2. Check if it is singular or plural:
* If it ends in 's' (like "witches"), it is plural.
* If it doesn't end in 's' (like "boy"), it is singular.
3. Apply the Rule:
* Singular nouns: Add 's (e.g., boy -> boy's).
* Plural nouns ending in s: Add just an ' (apostrophe) at the end (e.g., witches -> witches').
4. Reorder: Put the owner before the object.

Let's work through the list:

1. seeds of pumpkins: Owner is "pumpkins" (plural, ends in s). Change to "pumpkins'". -> pumpkins' seeds
2. ghosts of castles: Owner is "castles" (plural, ends in s). Change to "castles'". -> castles' ghosts
3. bones of skeleton: Owner is "skeleton" (singular). Change to "skeleton's". -> skeleton's bones
4. sleeves of costume: Owner is "costume" (singular). Change to "costume's". -> costume's sleeves
5. candle of jack-o-lantern: Owner is "jack-o-lantern" (singular). Change to "jack-o-lantern's". -> jack-o-lantern's candle
6. darkness of night: Owner is "night" (singular). Change to "night's". -> night's darkness
7. sparkle of stars: Owner is "stars" (plural, ends in s). Change to "stars'". -> stars' sparkle
8. liquid of glass: Owner is "glass" (singular). Change to "glass's" or "glass'". (Usually, for singular words ending in s, adding 's is acceptable and common in school grammar). Let's use glass's liquid.
9. carmel of apple: Owner is "apple" (singular). Change to "apple's". -> apple's carmel
10. wands of witches: Owner is "witches" (plural, ends in es/s). Change to "witches'". -> witches' wands
11. laughter of children: Owner is "children" (irregular plural, does not end in s). Change to "children's". -> children's laughter
12. mask of boy: Owner is "boy" (singular). Change to "boy's". -> boy's mask
13. lights of houses: Owner is "houses" (plural, ends in s). Change to "houses'". -> houses' lights
14. chattering of teeth: Owner is "teeth" (irregular plural, does not end in s). Change to "teeth's". -> teeth's chattering
