This March Tip of the Month introduces teachers to the foundations of morphology with a focus on suffix instruction. It clarifies key concepts like morphemes, roots, and bases while breaking down the difference between inflectional and derivational suffixes. Educators will learn why suffixes are critical for building vocabulary, how spelling rules connect to suffix use, and how to teach them through explicit, systematic routines. The post also provides practical classroom activities and games to make suffix learning engaging and meaningful for students.
