Developed by the Oregon Elementary English Project, the eighteen lessons in this unit aim to interest third and fourth grade students in thinking about how sentences are made, to introduce some grammatical concepts, and to build on the instinctive knowledge students already have about the English language. The first three lessons are devoted to the concept that words go together in an orderly way which we understand intuitively; lessons 4 and 5 demonstrate negative and question transformations; lessons 6 through 9 develop the noun phrase and verb phrase concepts; lessons 10 through 12 concentrate on noun recognition; lesson 13 introduces the pronoun; lessons 14 through 17 deal with verb recognition; and lesson 18 introduces the adjective. Each lesson is accompanied by a statement of its purpose, suggested procedures and materials, possible extensions, and student exercises. A packet of supplementary materials is also included.
