Another reason why printable questions and answers are so useful comes from the reality that you can make as numerous copies as you need for your class jobs. There are some scenarios where it would be more practical (and for that reason economical) to just offer the students one set of answers rather than an entire book or lesson.
Using group work in the class can be a great method to make class interaction more significant and remarkable. In some cases it’s simpler to ask questions to a larger group rather than whittle your answers down to a handful.
