Learning plural nouns can be challenging. If your third graders are having trouble with this grammar skill, this worksheet is key. It focuses on nouns that end in "ch," "sh," "ss," "x," "zz," "y," "f," and "fe." This resource includes the rules for forming the plural nouns. For example, if the noun ends in "f," drop the "f" and add "ves." Once your students form all 28 plural nouns, they will have a much better understanding of this concept.
