A group of six students were chosen to create posters during art club. At the end of art club, many students were still in the middle of working on a poster. The teacher asked students to record their progress as a proper fraction if they made less than one poster, record their progress as an improper fraction if they made between one and two posters, and record their progress as a mixed number if they made more than two posters. The teacher recorded these responses onto the whiteboard and asked students to place them on an open number line. What do you notice?
