These are flashcards that have been extremely successful in my classroom. Each word has three cards, the word, a definition, and a picture to represent the word. All of the the cards are linked through qr codes. In my classroom I usually print 3-5 sets, cut out the cards and laminate them. I have vocabulary sorting parties in my classes. I see which classes can work together to get the most complete sets. There are many other ways they can be used. Print the cards as 6 to 9 slides per page. I also have Characteristics of Life Presentation that goes along with the flashcards. URL is also inc. for product in google presentation format that you can copy and edit to your google drive.
