Give each student a newspaper article about a current event, and instruct them to write five sentences that discuss the main points of each article. Ask each student to stand in front of the class and read out their sentences. You can give them feedback as they present their ideas.
To help your students understand the importance of using the right verb tense for the subject of sentences, you can give each student a worksheet with 20 sentences that have multiple choices of verb tenses. The students would choose the right verb for each sentence.
You can encourage students' creativity and teach them good sentence writing skills by having them write a one-page paragraph about their families. Encourage them to discuss any unique facts about certain relatives and give them pointers on sentence structure before they write the paragraphs.
Another way to have fun while learning sentence structure is to have each student write five sentences that describe what they ate for lunch the previous day. Ask the students to be creative and to use humorous and colorful words in their descriptions.
