Post the pages around your room in a random order. The students may start on any letter. They write the letter they start at on the line on their answer sheet and solve the scientific notation problem. Then, they need to find the answer to their problem on the bottom of another page. They should write that letter on the little line and solve the problem on that page. They will continue around the room until they have been to every page. If they end up at the same one or they cannot find their answer then they did something wrong and should come ask the teacher.
