Another reason that printable questions and answers are so useful originates from the truth that you can make as many copies as you need for your classroom projects. There are some scenarios where it would be easier (and therefore economical) to just offer the students one set of answers rather than a whole book or lesson. You might wish to do some group deal with an approaching project that requires numerous long hours of description. In this case, it would be more cost-efficient 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 way to make class interaction more unforgettable and meaningful. In some cases it’s much easier to ask questions to a bigger group rather than whittle your answers down to a handful.
