Use the ruler to draw a line on the left side of the cardboard, starting about an inch from the top. Draw another line the same length on the right side of the cardboard. Write “questions” above the line on the left side of the cardboard. Write “answers” above the other line.

Starting at the top of the line, mark six evenly spaced dots along each line. They should be at least 1 inch apart. Label each hole in the “question” column 1 to 6. Label each hole in the “answer” column A to F.
