Change the way your students learn vocabulary with Flashcard Factory by Pear Deck. Students compete and work together in their respective groups in order to create sentences and illustrations. Students make arguments for their cards and the teacher accepts or rejects the arguments for approval. Once the cards are approved, they may be uploaded to Quizlet as part of their database of flashcards. The best thing about it is that a greater understanding of each of the vocabulary words is gained by adding the illustrations and sentences to each of the cards created. Try it out!
