Another reason why printable questions and answers are so useful originates from the fact that you can make as lots of copies as you need for your class tasks. There are some circumstances where it would be more convenient (and for that reason cost-efficient) to simply offer the students one set of answers rather than an entire book or lesson. You may wish to do some group work on an approaching job that requires a number of long hours of explanation. In this case, it would be more economical to just have a few group sheets printed rather than printing out a number of hundred pages of handouts.
Using group work in the classroom can be an excellent method to make classroom interaction more memorable and meaningful. Often it’s much easier to ask questions to a larger group rather than whittle your answers down to a handful.
