I created this fun activity to accompany my Plural Endings Sort and Plural Endings Sort 2. For this acticvity worksheet, students read and determine if each word should have an S added to make it plural, an ES or drop the Y and change to I then add ES. This could be a great seatwork activity during literacy stations or reading groups, morning work, homework, or even guided practice after introducing the topic of plural nouns. As an extension, using the color-coded words on the sheet, students can record the plural nouns into a journal or on a piece of notebook paper.
