Use the example screen before making groups.
Click on the power button to see the images and then click on the numbers to bring up the questions. Teams race to answer the questions and bring their answers to a teacher. If the answer is correct assign points based on speed or use random point cards. I sometimes go with speed but then after a few rounds add optional jankan with the teacher. They gain or lose points depending on if they win or lose.
I usually click the power button once. let the students take memos then click it again before starting on the questions. I usually do the questions in a random order.
After the time limit is up or after every team is finished to an answer check by clicking the same number again and then move onto a different question with a new student bringing their answer.
