This Grade 5 worksheet focuses on one of the trickiest and most important grammar topics — comparing adjectives with irregular forms. Unlike regular adjectives that follow predictable patterns, irregular adjectives like good, bad, and far change completely in their comparative and superlative forms: good → better → best, bad → worse → worst, far → farther → farthest. This worksheet helps students master these forms through five engaging and well-structured activities that move from recognition to application.
Irregular comparison forms are a key part of fluent English usage. For Grade 5 learners, this topic is important because:
1. Regular adjectives use -er/-est or more/most, but irregular ones follow entirely different patterns.
2. The three main irregular adjectives covered are good, bad, and far.
3. Using the wrong form (e.g., "more better" or "worser") is a very common error that this worksheet corrects.
4. These forms appear frequently in both formal writing and everyday speech.
5. Understanding superlatives vs. comparatives builds clearer and more expressive sentences.
This worksheet includes five grammar-rich activities that build mastery of irregular comparison forms:
Exercise 1 – Multiple Choice Questions
Students choose the correct comparative or superlative form of an irregular adjective from three options. This builds their instinct for identifying which form fits — better vs. best, worse vs. worst, farther vs. farthest.
Exercise 2 – Fill in the Blanks (Choose One from a Pair)
Students select the more appropriate irregular comparison form from a given pair to complete each sentence meaningfully. This helps them distinguish between comparative and superlative usage in context.
Exercise 3 – Match the Following
Students match each sentence to the correct comparison form from a list on the right, reinforcing their understanding of when to use comparative vs. superlative forms.
Exercise 4 – Underline the Incorrect Comparison Form
Students read each sentence and underline the incorrect comparison form. This error-spotting task helps them recognize common mistakes like "more better," "worser," and "more far."
Exercise 5 – Paragraph Writing with Irregular Comparison Forms
Students fill in blanks in a connected paragraph with suitable irregular comparison forms. This activity challenges students to apply all three adjective sets — good/better/best, bad/worse/worst, far/farther/farthest — in a natural writing context.
Exercise 1 – Multiple Choice Questions
1. b) better
2. c) best
3. a) better
4. b) farther
5. c) best
6. b) worse
7. a) farther
8. c) best
9. b) worse
10. c) farthest
Exercise 2 – Fill in the Blanks
1. better
2. best
3. farther
4. better
5. best

2. best
3. farther
4. worse
5. worst
6. farthest
7. best

Exercise 4 – Underline the Incorrect Comparison Form
1. more better (incorrect — should be "better")
2. good (incorrect — should be "best")
3. worser (incorrect — should be "worse")
4. more farther (incorrect — should be "farther")
5. better (incorrect — should be "best")

Irregular adjectives like good, bad, and far change form differently when making comparisons.
Because they do not follow the normal “-er” or “more” comparison rules in English grammar.
Irregular adjective comparisons change their form instead of just adding "er" or "est." For example, "good" becomes "better" and "best," while "bad" becomes "worse" and "worst."
