What Are Opposite Words Flashcards?
Opposite words flashcards are a simple and effective way to teach children adjectives and basic vocabulary. Each card shows a word and its opposite, such as big–little, hot–cold, or happy–sad.
These cards help children understand comparisons, describe their world, and build memory faster. For ESL learners, learning opposites means they can double their vocabulary with each pair.
