This activities requires students to determine the definitions of common and proper nouns and abstract and concrete nouns. They then have to decide whether different nouns are common, proper, abstract, or concrete. I have include the options of using QR codes as well as a set that does not include QR codes. My students love these activities. I print them on colored card stock and then cut them apart. There are 48 multiple choice questions and an answer sheet for them to record their responses. I include two options for recording sheets. One they just write their answers, and the other they write their answer, and then check whether their answer was right or wrong. Please let me know if you have any questions.
