A resource that I use as well as several other teachers at my school is quizlet.com . This site allows you to create vocabulary “cards” for the topic of study. Then you provide students a link and they can use it to study as flashcards, write them, spell them, and/or do a practice test. You can also provide a given code with quizlet live and the students are put into teams and race against each other to match or answer questions over the terms you submitted.
