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 class projects. 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 class can be a terrific way to make class interaction more memorable and meaningful. It can also make the lessons more enjoyable for students. If you have actually always done a group work exercise then you most likely understand that you don’t constantly get to select the exact same questions. Often it’s easier to ask questions to a larger group rather than whittle your answers to a handful. By giving everyone a chance to share their understanding, you’ll be able to produce lessons that truly matter.
