Another reason why printable questions and answers are so helpful comes from the fact that you can make as numerous copies as you need for your class jobs. There are some circumstances where it would be more convenient (and for that reason cost-effective) to just provide the students one set of answers rather than a whole book or lesson.
Using group work in the classroom can be a great way to make class interaction more unforgettable and significant. Often it’s much easier to ask questions to a larger group rather than whittle your answers down to a handful.
