The past simple tense is used to talk about completed actions or states in the past. For regular verbs, the past simple is formed by adding -ed to the base form of the verb. Here are some examples of regular verbs in the past simple tense:

1. I walked to school yesterday.
2. She played the piano beautifully.
3. They watched a movie last night.
4. We cleaned the house on Saturday.
5. He cooked dinner for his family.
6. The dog barked loudly.
7. She laughed at the joke.
8. They studied for the exam.
9. We visited our grandparents over the weekend.
10. He helped his friend with the project.

Remember that some regular verbs have irregular past forms, so it’s important to learn those irregular forms separately.
