When teaching the inflectional ending -ed, what practice should a teacher engage in?

Engaging in the practice of writing -ed on the board and defining it is an effective method for teaching this inflectional ending because it directly addresses students' understanding of how -ed functions in the formation of past tense verbs and adjectives. By visually presenting the ending and providing a definition, students can connect the spelling to both the phonetic and grammatical aspects of word formation. This approach also allows for clarity and reinforces recognition of its application in context, making it easier for students to grasp its usage in terms of forming past tenses or indicating completed actions.

In this method, teachers can provide ample examples of regular verbs, demonstrating how the rule applies consistently, which promotes familiarity and confidence in using the inflectional ending correctly.
