Nouns Lesson, Grades 3-4: Irregular Plural Nouns

One foot, two foots? In about 40 minutes, students learn three kinds of irregular plural nouns and how to tell them from regular plurals. The lesson opens with a question students already know the answer to, then teaches the three kinds: nouns that change their vowels (man, men; foot, feet; tooth, teeth; goose, geese; mouse, mice), nouns that end in -en (child, children; ox, oxen) and nouns that stay the same (sheep, deer, moose). A model slide shows students how to ask "regular or irregular?" and includes look-alikes that just add -s, such as pens.
