Which is the best concluding sentence for this paragraph? a) teachers should make their cell phone enemy into an ally to make their classrooms come to life. b) technology today can do so many amazing things and so many of them are useful for educational purposes. c) on the other hand, cell phones are also extremely distracting and probably are best left outside of the classroom. d) another item of technology that teachers should not be afraid to use in their classrooms are computer tablets and laptop carts.

A definitely! It provides more closure for the paragraph. However, I would change some of the wording in your sentence. For example, I would use a transitional phrase to close the paragraph. Try investigating in some transitional phrases that are used to close a paragraph (ex. overall, in conclusion, etc). Once you’ve chosen one, pop it in front of the sentence and add a comma! In addition, instead of saying “teachers should make their cell phone enemy into an ally”, i would say “teachers should transform their once enemy of the cell phone into their ally in order to bring life to the classroom”.
