This exercise is designed for 6th-grade students to help them improve the use of articles "a" and "an" through long sentences and diverse examples. Students will learn when to use "a" or "an" based on whether the word starts with a vowel or consonant sound, with opportunities to practice in real-life contexts. The exercise includes three parts: first, identifying vowels; second, filling in the blanks with the correct article; and finally, matching words with the appropriate article. Enjoy enhancing your language skills while playing and learning.
