Another reason why printable questions and answers are so beneficial comes from the truth that you can make as many copies as you need for your class tasks. There are some situations where it would be more convenient (and for that reason cost-efficient) to simply provide the students one set of answers rather than a whole book or lesson.
Utilizing group work in the classroom can be a great method to make class interaction more remarkable and meaningful. Often it’s easier to ask questions to a bigger group rather than whittle your answers down to a handful.
