This powerpoint goes over all the rules for capitalization. It also includes pronoun rules as a bonus in the second part of the powerpoint. This can be used in a virtual classroom or traditional setting with a smart board (or similar device). There are 5 slides where students practice by circling (or pointing to) the sentence that is capitalized correctly.
This would make a great mini lesson as part of your writing lessons. This lesson also aligns with Study Island.
