Teaching prefixes and suffixes is an essential part of building proficient readers. Students that learn affixes are prepared to break down longer and more difficult words into parts that are more easily understood. Not only does an understanding of prefixes and suffixes improve decoding skills, but it also boosts comprehension. Learning affixes also demystifies the process of spelling. This deck consists of prefix and suffix cards with definitions and illustrated for additional support, as well as matrixes and word sums. The activity is aligned to the Reading Literature and Informational standards.
