This quiz tests ten math vocabulary words using a yes, no, why format. This format is great for showing a deep understanding of math vocabulary words. This quiz is based on PSSA (Pennsylvania) math vocabulary for grades 3-5, but would be a great test prep review for many grade levels. Each of the three pages gives students a statement using a math vocabulary word and asks them to circle yes or no to answer the question, and then show a deeper understanding by having them write why the answer is what they have chosen. This is one of twelve quizzes to be posted.
