Station 4. Directions: Each slide will present a sentence. . Write the sentence on your paper.. Identify if the sentence is complex or compound-complex.. After EVERYONE in the group has written the sentence & made a selection, check your answer by pressing the space bar.. .. . Once a student knows the difference between the three sentence types (simple, compound, and complex), it is possible to write with sentence variety. Sentence variety helps make your writing more interesting.. MACROSCOPIC SCALE. Elements combine to make compounds.. ATOMIC SCALE. Atoms combine to make molecules, or extended structures..
