It’s Leadership Day in Mr. Wright’s classroom, and the prefixes are IMpatient to take center stage. After all, they are the greatest leaders around! Prefixes attach to the beginning of words and change what they mean. But they are MIStaken about their role in the day’s festivities. . . . Mr. Wright has a lesson on President Abraham Lincoln PREpared. The prefixes are in DISbelief that they could be so carelessly IGnored. Luckily, Mr. Wright gets a REminder to include them in the lesson and the prefixes are ready to UNleash their power.
