Practice identifying and writing the past tense forms of regular and irregular verbs.

Problem Overview:

The task involves identifying irregular verbs from a list of present tense verbs and writing their correct past tense forms. The worksheet explains the difference between regular and irregular verbs:
- Regular verbs form their past tense by adding "-ed" (e.g., "talk" → "talked").
- Irregular verbs do not follow this rule and have unique past tense forms (e.g., "sing" → "sang").

Solution Approach:

1. Identify Irregular Verbs: Determine which verbs in the list do not follow the "-ed" rule for forming the past tense.
2. Write Past Tense Forms: For each verb, write its correct past tense form. If the verb is irregular, circle it.
