Exercise Solutions

Solution to Question 1: Both words share the diphthong sound /ɔɪ/. Coin is spelled with oi because it sits in the middle of a syllable; boy is spelled with oy because English words typically use oy at the end of a word or syllable.

Solution to Question 2: The combination making /ɔːr/ is or. The triplets making /ɜːr/ are er, ir, and ur.

Solution to Question 3: Volcano divides as vol-ca-no. The middle syllable ca is open (ends in vowel a), producing a long a sound.

Solution to Question 4: The FLOSS rule states that one-syllable words with one short vowel ending in f, l, s, or z double the final consonant. Grass follows the rule (double ss); gas is one of the rare common sight word exceptions with a single s.

Solution to Question 5: In unhelpfully: Base word = help; Prefix = un-; Suffixes = -ful and -ly.

Solution to Question 6: Their shows ownership (their backpacks); there indicates a place (over there); they're is a contraction for they are.

Solution to Question 7: Weakest to strongest: warm, hot, boiling.

Solution to Question 8: Alphabetical order: space (spa-), speed (spe-), spill (spi-), spoon (spo-).

Solution to Question 9: Playful is an Adjective; barked is an Action Verb; loudly is an Adverb (manner); under is a Preposition.

Solution to Question 10: The plural possessive form is: the girls' treehouse (apostrophe after the s).

Solution to Question 11: Comparative = heavier (change y to i); Superlative = heaviest (change y to i).

Solution to Question 12: The correct choice is hoots ("the wise old owl hoots" because singular owl pairs with hoots ending in s).

Solution to Question 13: Declarative (period .); Interrogative (question mark ?); Imperative (period . or exclamation point !); Exclamatory (exclamation point !).

Solution to Question 14: Corrected sentence: "On Monday, Maya and I saw three deer in Yellowstone." (Capitalize On, Monday, Maya, Yellowstone; change me to I; change deers to zero-change plural deer; add end period).

Solution to Question 15: "Carlos wanted to play outside, but the heavy rain poured down."

Solution to Question 16: Leo shouted, "Watch out for that bee!" (Comma after shouted, quotation marks around spoken words, capital W, end mark inside quotes).

Solution to Question 17: A feeling is temporary and changes rapidly based on circumstances (like feeling frustrated for five minutes); a character trait is enduring and defines a person's lasting personality (like being persistent or brave).

Solution to Question 18: A topic is a one- or two-word general label (like "Sharks"); a main idea is a complete sentence stating the central assertion or point the author proves about that topic.

Solution to Question 19: The five parts in order are: 1. Heading (date), 2. Greeting, 3. Body, 4. Closing, 5. Signature.

Solution to Question 20: O-R-E-O stands for: Opinion (state your belief), Reason (explain why), Example (provide proof/facts), Opinion (restate your belief in fresh words).

Solution to Exercise 1: Answers will vary based on individual growth; for example, a student might highlight mastering vowel teams or writing structured five-sentence paragraphs.

Solution to Exercise 2: A student could write: Becoming a stronger reader and writer prepares me for third grade because I can now decode multisyllable chapter books independently and understand complex science texts. In writing, knowing how to plan, draft, revise, and edit ensures that I can write multi-paragraph reports and exciting personal narratives with complete confidence.
