Worksheet Preview
Same or opposite?
Synonyms are words that mean the same (big/large), and antonyms are words that mean the opposite (hot/cold). A strong sense of synonyms and antonyms makes reading sharper and writing far more interesting.
The memory hook
- Synonym = Same
- Antonym = Against (opposite)
Worked examples
Synonym of big → large, huge, giant (any word with the same meaning counts). Antonym of hot → cold (the opposite).
How to solve each item
For synonyms, ask “What’s another word that means the same?”; for antonyms, “What’s the opposite?” Many words have more than one right answer, so any correct word is accepted.
Guided practice (try before the worksheet)
- Synonym of fast → quick
- Antonym of empty → full
- Synonym of begin → start
- Antonym of brave → afraid
Why it matters for writing
Synonyms let you vary your word choice so writing isn’t repetitive; antonyms sharpen descriptions and comparisons. Build this habit and your vocabulary grows word pair by word pair.
Next steps
Pairs with prefixes and suffixes to grow vocabulary even faster, and with context clues to meet new words while reading.
👩🏫 Teacher note
Synonym = same (S for same), antonym = opposite. Knowing synonyms helps students vary word choice in writing; antonyms sharpen meaning.
🏠 Parent note
Ask 'What's another word that means the same?' for synonyms and 'What's the opposite?' for antonyms.
Common Mistakes to Watch For
- Mixing up synonym and antonym
- Choosing a related word that isn't the same or opposite
