The teacher asks a question within a given subject and if the student can answer the question the aim is to be the fastest to perform an active challenge. Some examples could be standing on a chair, sitting on a table, spinning around themselves, clap five times etc. The fastest one to complete the challenge is allowed to answer. If the answer is correct they get a point, if the answer is wrong they get a minus point.The teacher could possibly change the active challenges after every five questions. If the students are in groups it would be the fastest student’s group who are allowed to answer.
