Another reason why printable questions and answers are so beneficial comes from the fact that you can make as many copies as you require for your classroom projects. There are some circumstances where it would be more practical (and therefore cost-effective) to just give the students one set of answers rather than a whole book or lesson.
Using group work in the class can be an excellent method to make class interaction more unforgettable and meaningful. In some cases it’s much easier to ask questions to a larger group rather than whittle your answers down to a handful.
