By the end of this lesson, you will appreciate the role of mathematics in understanding and describing the world around you.

## Objectives Of Learning The Chapter “What’s In The Name?”

In this chapter, “What’s in a Name?”, our objective is to help students understand the significance of names in mathematics. By exploring how names identify numbers and shapes, we aim to enhance their ability to communicate mathematical ideas effectively. Students will learn to recognize and articulate the characteristics of various mathematical objects, fostering a deeper appreciation for the role of mathematics in everyday life. Through engaging activities and examples, we aspire to cultivate not only knowledge but also confidence in using mathematical terminology, laying the groundwork for future learning in mathematics.

**Understanding Names in Mathematics**

Just like how each person has a unique name that identifies them, in mathematics, we use names for various objects, shapes, and numbers. These names help us communicate our ideas.

**Why Do We Need Names?**

Further in the chapter “What’s in a Name?” we explore an answer to the question, why do we need names. This involves-

**Identification**: Names help in object identification. For example, a square is referred to as a “square” because it has four equal sides and four right angles.**Communication**: Using particular labels for numbers and shapes helps efficient communication when discussing math challenges. For example, you can tell right away that when I say “triangle,” I’m speaking of a shape with three sides.**Learning**: Knowing mathematical terms improves the understanding of ideas. Understanding the terms and features of kinds helps us solve problems more efficiently.

**Fun with Counting**

When there are more objects to count, marking is quite helpful. Students can make marks in groups, such as by bundling marks in groups of five, to avoid becoming disoriented or losing track. To make it simpler to add up to bigger numbers, they may mark the objects as ||||| ||||| ||, for example, if there are 12 objects. This way, each group of five is grouped.

This method provides a physical representation of each item, which ensures accuracy and encourages careful counting. Additionally, it aids in the early development of grouping and numerical pattern comprehension skills. All things considered, using marking to assist with counting is a fundamental method that helps young students effectively understand amounts and numbers.

**Activity: Identifying Shapes**

Now let’s get started with a task! Observe your classroom and note the various shapes there. Are there any triangles, squares, rectangles, or circles that you can see? Share a list of the shapes you observe with your fellow students.

**What Are Numbers?**

Further in the chapter What’s in a Name?, we’ll understand what are numbers. Numbers are symbols we use to count, measure, and label. They help us quantify objects and understand relationships.

**Activity: Counting Objects**

Let’s practice counting! Find a group of objects in your classroom, such as books or pencils. Count how many there are and write down the number. Then, share your findings with your classmates.

**The Importance of Numbers**

The chapter “What’s in a Name?” gives a clear understanding of the importance f the number. The ones place and the tens place are the two positions in two-digit numbers. For instance, the digits “4” and “7” in the number 47 represent 40 and 7, respectively, in the tens and ones places. They make up 47 in total. When students count, they add one more to the place of one to go from one number to the next.

- For example: Begin at 34. The following number is 35, where the one’s location is increased by 1.
- The tens place changes when the one’s place reaches nine, after which one is added. For example, 40 comes after 39.

Students can identify patterns in numbers by counting by tens (10, 20, 30, 40, etc.) when working with two-digit numbers. This gets them ready to comprehend bigger numbers and carry out addition and subtraction tasks. In order to assist kids develop number sense and get familiar with numbers up to 99 and beyond, counting two-digit numbers is an essential first step.

**Learning Number Names**

Learning number names in Class 3 is an important step in understanding how to read and write numbers in words. It helps students connect the numerical symbols they see with their corresponding word forms, enhancing their number sense and comprehension.

For two-digit numbers, students learn how to combine the names of the tens and ones places. For example:

**21**is read as “twenty-one.”**45**is read as “forty-five.”**68**is read as “sixty-eight.”

Here’s how it works:

**Tens place:**Numbers like 20, 30, 40, etc., are named as “twenty,” “thirty,” “forty,” and so on.**One’s place:**The numbers from 1 to 9 are named as “one,” “two,” “three,” etc.- When writing a two-digit number, students combine these names. For example, 54 is written as “fifty-four,” where “fifty” represents 50, and “four” represents the 4.

Special attention is also given to numbers like 11-19, which don’t follow the regular pattern:

**11** is “eleven,” **12** is “twelve,” and so on.

By practicing number names, students gain confidence in reading and writing numbers, which is essential for their mathematical development and everyday life.

**Grouping**

The concept of grouping in Class 3 math is a fundamental strategy to help students understand how large numbers are organized and counted efficiently. Grouping means organizing objects or numbers into smaller, manageable sets to make counting, addition, or multiplication easier.

For example, if a student has 15 pencils, instead of counting each pencil individually, they can group them into sets of 5:

- Three groups of 5 pencils each: 5 + 5 + 5 = 15.

**Patterns and Relationships**

In mathematics, we also explore patterns and relationships. Patterns are sequences that follow a specific rule. Recognizing patterns helps us make predictions and solve problems.

**Types of Patterns**

**Number Patterns**: A sequence of numbers that follows a specific rule. For example: 2, 4, 6, 8 (adding 2 each time).**Shape Patterns**: A sequence of shapes arranged in a specific order. For example: triangle, square, triangle, square (alternating shapes).

**Activity: Create a Pattern**

Let’s create our own patterns! Use colored paper or drawing materials to make a pattern using shapes or colors. For example, you could create a pattern using red circles and blue squares.

**Recognizing Patterns in Life**

Patterns are not only found in math but also in nature, art, and music. Recognizing these patterns helps us understand the world better.

**Nature**: Many plants and animals exhibit patterns, such as stripes on a zebra or the petals of a flower.**Art**: Artists often use patterns to create visually appealing designs.**Music**: Musical compositions frequently have repeating patterns and rhythms.

**Conclusion**

In conclusion, the CBSE Class 3 Math Chapter 1 – What’s in a Name? Provides students with a foundational understanding of how names in mathematics—such as numbers and shapes—help us communicate and solve problems effectively. Through activities like counting objects, identifying shapes, and recognizing patterns, students develop essential skills that will support their learning journey. Understanding the concepts from What’s in a Name? is not only crucial for academic success but also for everyday problem-solving.

As you move forward, remember that Chapter 1 – What’s in a Name? Serves as a building block for more complex mathematical ideas. Embrace the patterns, numbers, and names around you—they are more than just symbols; they are the language of mathematics that will help you better navigate the world!

**Key Takeaways**

**Names in Mathematics**: Names help us identify and communicate different mathematical objects.**Numbers**: Numbers are used to count, measure, and label, and they play a vital role in our daily lives.**Patterns**: Recognizing patterns helps us make predictions and understand relationships in mathematics and nature.
