To make the cards cut into rows. You then fold in half and either glue or laminate. One side is then question (which the students shows to others) and the other side is the Q and answers.Students have 1 card each & they test each other in pairs by asking the questions on the back. They take this in turns and then they trade cards and find another partner. They do this for a set time (5-10 mins).As a teacher you can go round and join in and ensure that you are satisfied that students understand.
