Here is a revised version of your paragraph in approximately 150 words, suitable for Class 3 students:

Student of Class 6 are requested to bring one notebook and their stationery tools (like pencil, eraser, sharpener, ruler, etc.) to the class. In this lesson, we will learn about nouns and their different types. A noun is the name of a person, place, animal, or thing. We will also discuss how we use nouns in our daily life — for example, when we talk about our family, school, or favorite toys. The teacher will explain everything in a very simple and easy way so that all students can understand. Fun activities and examples will be used to help students learn quickly. After the explanation, students will be given exercises to practice identifying and using nouns correctly. Each step will be taught clearly, and students can ask questions if they don’t understand something. Let’s get ready to enjoy learning nouns in a fun and exciting way!
