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