Another reason that printable questions and answers are so useful originates from the truth that you can make as many copies as you require for your class tasks. There are some circumstances where it would be easier (and for that reason cost-efficient) to just provide the students one set of answers rather than an entire book or lesson. You may wish to do some group work on an upcoming project that requires numerous long hours of description. In this case, it would be more cost-efficient to simply have a couple of group sheets printed instead of printing out several hundred pages of handouts.
Using group work in the classroom can be an excellent way to make classroom interaction more memorable and significant. In some cases it’s simpler to ask questions to a bigger group rather than whittle your answers down to a handful.
