This handout is meant to accompany any vocabulary unit. The students write the vocabulary word and its definition in the butterfly's body. Then, in the wings, they write any words or phrases that will help remind them of the vocabulary word. (I've included an example page in the download.) I've used this as both individual work and group work. For group work, I assign each student a vocabulary word. Then we pass the butterflies around until each student has written a "reminder word" on every butterfly.
