Another reason why printable questions and answers are so useful comes from the fact that you can make as numerous copies as you need for your class projects. There are some circumstances where it would be more hassle-free (and for that reason cost-efficient) to simply provide the students one set of answers rather than an entire book or lesson.
Using group work in the classroom can be a great way to make classroom interaction more remarkable and meaningful. Often it’s simpler to ask questions to a bigger group rather than whittle your answers down to a handful.
