FAQs on Tens and Ones Class 2 Worksheet Maths Chapter 8

1. What are tens and ones?
Ans. Tens and ones are a way to represent numbers in a place value system. The tens place represents the larger value digit, while the ones place represents the smaller value digit. For example, in the number 45, the digit 4 is in the tens place and represents 40, while the digit 5 is in the ones place and represents 5.
2. How do you count tens and ones?
Ans. To count tens and ones, you start by counting the tens. Each time you count to 10, you add one to the tens place. After counting the tens, you move on to the ones place and count from 1 to 9. Once you reach 9 in the ones place, you add one to the tens place and start counting the ones from 0 again.
3. How can tens and ones be helpful in addition and subtraction?
Ans. Tens and ones are helpful in addition and subtraction as they allow us to break down numbers into their place value components. When adding or subtracting two-digit numbers, we can focus on the tens place and ones place separately and then combine the results. This makes the calculations easier and more organized.
4. Can you give an example of using tens and ones in a math problem?
Ans. Sure! Let's say we want to add 23 and 17 using tens and ones. We start by adding the ones place: 3 + 7 = 10. Since we have 10 ones, we regroup it as 1 ten and 0 ones. Then, we add the tens place: 2 + 1 + 1 (from regrouping) = 4. Therefore, 23 + 17 = 40.
5. How can I teach my child about tens and ones?
Ans. Teaching tens and ones can be done through various hands-on activities and visual aids. You can use base-10 blocks or drawing pictures to represent tens and ones. Start by explaining the concept of place value, then demonstrate how to count and regroup tens and ones. Practice with simple addition and subtraction problems involving two-digit numbers to reinforce the understanding of tens and ones.
