Another reason why printable questions and answers are so useful comes from the fact that you can make as numerous copies as you need for your classroom projects. There are some situations where it would be more practical (and therefore economical) to simply give the students one set of answers rather than a whole book or lesson.
Utilizing group work in the classroom can be an excellent method to make class interaction more remarkable and significant. Often it’s simpler to ask questions to a bigger group rather than whittle your answers down to a handful.
