Spelling Grade 5 — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A pack of hungry wolves howled at the moon.
Wolf becomes wolves; words ending in -lf typically switch f to v before adding -es.
2. The geese flew south for the winter season.
Goose becomes geese through a vowel change, similar to foot becoming feet.
3. Firefighters are real heroes in our community.
Hero ends in consonant plus o, so the plural takes -es rather than just -s.
4. We brushed our teeth before going to bed.
Tooth becomes teeth through an Old English vowel change, not a regular -s ending.
5. The chef made spicy potatoes for dinner tonight.
Potato ends in consonant plus o, so -es is added to form the plural.
6. Two women stood at the front of the room.
Woman becomes women; only the middle vowel sound changes in the irregular plural.
7. I have two feet on my left foot now.
Foot becomes feet, following the same vowel-change pattern as tooth and teeth.
8. The library has shelves full of books to borrow.
Book ends in a consonant cluster, so the regular -s plural rule applies.
9. The chorus sang in many different voices today.
Voice already ends in -ce, so only -s is added to make the plural voices.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.

tomatoes
