Class 2 Syllabus – Mathematics Chapter 8: Tens and Ones: In this chapter, we will explore the concept of tens and ones in the context of numbers. Understanding tens and ones is fundamental to developing a strong foundation in place value, which is crucial for performing mathematical operations accurately. We will learn how to represent numbers using tens and ones, and how to perform addition and subtraction with these units.
8.1 Understanding Place Value
We start by revisiting the concept of place value. In our number system, each digit’s position in a number holds a specific value based on powers of 10. The rightmost digit represents the ones place, followed by the tens place, hundreds place, and so on. The value of each digit depends on its position in the number.
For example, in the number 53, the digit 5 represents the tens place, and the digit 3 represents the ones place. The value of 5 is ten times greater than the value of 3 because it is in the tens place.
8.2 Representing Numbers using Tens and Ones
To represent numbers using tens and ones, we group them accordingly. Each group contains ten ones, forming a new unit called a “ten.” This grouping allows us to easily understand and manipulate larger numbers.
Let’s take the number 37 as an example. We can represent it as 3 tens and 7 ones. This means we have 3 groups of ten and 7 individual ones. We can represent this visually as:
37 = 3 tens + 7 ones
We can also represent it using a place value chart:
Tens Ones
3 7The place value chart helps us visualize the number’s composition and understand the value of each digit.
8.3 Addition and Subtraction with Tens and Ones
Using the concept of tens and ones, we can perform addition and subtraction more easily. When adding or subtracting numbers, we start by focusing on the ones place and then move on to the tens place if necessary.
Let’s consider the addition problem: 26 + 14.
We start by adding the ones place: 6 + 4 equals 10. Since we have ten ones, we can regroup them as one ten and zero ones. So, we write down the zero in the ones place and carry the one to the tens place.
26- 14
40
Now, let’s look at a subtraction problem: 58 – 27.
We start by subtracting the ones place: 8 – 7 equals 1. Next, we subtract the tens place: 5 – 2 equals 3. Therefore, the answer is 31.
58- 27
31
8.4 Practice Exercises
To solidify our understanding of tens and ones, it’s important to practice working with numbers in this format. We can solve various addition and subtraction problems involving tens and ones to build our proficiency.
Example:
Add: 34 + 27
Solution:
First, add the ones place: 4 + 7 equals 11. Write down 1 in the ones place and carry the ten to the tens place. Then, add the tens place: 3 + 2 (carried ten) equals 5. Thus, the answer is 61.
34- 27
61
By practicing these exercises, we become more comfortable with manipulating numbers using tens and ones and strengthen our overall arithmetic skills.
Chapter 8 Summary:
In this chapter, we explored the concept of tens and ones as it relates to numbers. We learned how to represent numbers using tens and ones, and how to perform addition and subtraction with these units. Understanding the
place value system and the relationship between tens and ones is essential for building a solid foundation in mathematics.
