Why Lesson Planet?
Designated for English Learners, here is a worksheet that would also help native speakers with mastering prefixes that indicate negativity. It explains the prefixes im-, in-, mis-, non-, and un-, and gives root words that match each of them. Learners connect the prefixes and roots, writing the new words on lines provided. Finally, they use some of the words to fill in the blanks in four sentences with images to help with comprehension.
