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 jobs. There are some situations where it would be more hassle-free (and therefore economical) to simply give 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 classroom interaction more significant and memorable. In some cases it’s easier to ask questions to a larger group rather than whittle your answers down to a handful.
