Another reason that printable questions and answers are so beneficial comes from the fact that you can make as lots of copies as you need for your classroom tasks. There are some circumstances where it would be more convenient (and therefore economical) to simply provide the students one set of answers rather than an entire book or lesson. You might wish to do some group work on an approaching task that requires a number of long hours of explanation. In this case, it would be more economical 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 a terrific way to make classroom interaction more memorable and significant. Often it’s easier to ask questions to a larger group rather than whittle your answers down to a handful.
