This slideshow adds to the introduction to subject-verb agreement that I provided as a free slideshow.

The lesson offers the following:

1.) A brief review of the concept
2.) A simple working definition
3.) A brief review of subject and verb
4.) Three examples of how subject-verb agreement functions in a sentence
5.) Fifteen interactive review questions with built in answer keys (I have students show their answer choices by "finger voting" on the count of three-1 finger = A, 2 fingers = B, and so on)
