Another reason why printable questions and answers are so beneficial comes from the truth that you can make as many copies as you require for your class projects. There are some scenarios where it would be more convenient (and for that reason affordable) to just offer the students one set of answers rather than a whole book or lesson.
Using group work in the class can be a great method to make class interaction more unforgettable and significant. In some cases it’s much easier to ask questions to a bigger group rather than whittle your answers down to a handful.
