A great, fun way to practice antonyms!
Copy and laminate several sets of the cards (enough to have your class in groups of 3 or 4)
Put class into groups of 3 or 4.
Students will set out all of the cards, face up.
You will go through the teacher script. The first student to slap each correct synonym gets to keep that card.
At the end of the round, whoever has the most cards in each group wins.
I have students put a card back if they slap the wrong one.
My kiddos love this game, hope yours do too!
