Another reason why printable questions and answers are so useful comes from the truth that you can make as numerous copies as you require for your class projects. There are some scenarios where it would be more convenient (and therefore cost-effective) to just give the students one set of answers rather than an entire book or lesson.
Using group work in the class can be an excellent way to make classroom interaction more significant and memorable. In some cases it’s easier to ask questions to a bigger group rather than whittle your answers down to a handful.
