I use these with my students to practice written Mclass written stems. I cut these sets out and put them in baggies for each level. The students use library books and classroom book on their level and they paste a stem at the top, write their name and date. They answer the question and then take an AR test on the book and write their grade. They can be used in a practice stem notebook. They can be used for homework and classwork. It really helped my students be experts at these stems.
