Another factor why printable questions and answers are so useful comes from the fact that you can make as many copies as you need for your class jobs. There are some situations where it would be more convenient (and for that reason economical) to just give the students one set of answers rather than a whole book or lesson.
Using group work in the classroom can be an excellent way to make class interaction more meaningful and remarkable. In some cases it’s simpler to ask questions to a larger group rather than whittle your answers down to a handful.
