Another reason printable questions and answers are so helpful originates from the truth that you can make as many copies as you require for your classroom projects. There are some circumstances where it would be easier (and for that reason economical) to just offer the students one set of answers instead of an entire book or lesson. You might want to do some group deal with an approaching project that needs numerous long hours of description. In this case, it would be more cost-effective to just have a couple of group sheets printed rather than printing out several hundred pages of handouts.
Utilizing group work in the classroom can be a great way to make classroom interaction more meaningful and memorable. Often it’s simpler to ask questions to a bigger group rather than whittle your answers down to a handful.
