Spelling Grade 5 — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. We read three different stories this month.
Story ends in consonant plus y, so the y changes to i and -es is added.
2. The boys in our yard sing every morning.
Boy ends in vowel plus y, so the y stays and only -s is added.
3. Three mice ran across the barn floor.
Mouse becomes mice through an irregular vowel change, not a normal -s ending.
4. The children played quietly in the playground.
Child becomes children, an Old English plural that does not follow standard rules.
5. She packed two knives for the camping trip.
Words ending in -fe often change f to v before adding -s, giving knives.
6. I bought a bunch of ripe berries at the market.
Berry ends in consonant plus y, so it follows the y-to-ies plural rule.
7. The kids brushed their teeth after lunch.
Kid ends in a consonant, so the regular -s rule applies for the plural.
8. Two planes landed safely on the runway.
Plane ends in silent e, so only -s is added without doubling or changing letters.
9. The farmer kept five calves in the field.
Calf becomes calves; words ending in -lf often switch f to v before -es.
