9 sets of 3 simple, hand-drawn flashcards, each representing superlatives. You can choose the words you’d like to teach that fit each set. Some suggestions are:
far/farther/farthest – near/ nearer/nearest,
fuffy/fluffier/fluffiest or furry/furrier/furriest,
tall/taller/tallest or big/bigger/biggest,
I suggest printing them on thicker paper, cutting them into individual cards and laminating for durability.
