These amazing geometry flash cards are designed to help your students master the vocabulary and concepts of circles. There are 10 sets, and each has a term, definition, and picture. I recommend that you group your students into pairs so that they can work together, and you will see how exciting it is to hear your class buzzing with the words and discussions of what they mean! This cooperative learning process is so valuable to all students, but especially your English language learners! These cards were created for you by Judy Seki of "Math in a Flash!"
