 Today, I shall teach you about the counting on method in adding numbers. In this method, it is useful to know which number is bigger or greater. We shall use your fingers to represent the smaller add-in. How do we do the counting on method in addition? Have a look of these samples that I am going to show you. What is the sum of 9 plus 5? Here we can see that 9 is the greater number. So we put up 5 fingers for the smaller number and we count on 9, 10, 11, 12, 13, 14. 9 plus 5 equals 14. What is the sum of 4 plus 7? We see here that 7 is the greater number, so put up 4 fingers. And then we count on 7, 8, 9, 10, 11. 4 plus 7 equals 11. What is the sum of 8 plus 6? Here we see that 8 is the greater number, so put up 6 fingers. Then we count on 8, 9, 10, 11, 12, 13, 14. 8 plus 6 equals 14. What is the sum of 4 plus 9? 9 is the greater number. So put up 4 fingers for the smaller add-in. We count on 9, 10, 11, 12, 13. 4 plus 9 equals 13. What is the sum of 6 plus 3? 6 is the greater number. Put up 3 fingers. And then we count on 6, 7, 8, 9. 6 plus 3 equals 9. What is the sum of 9 plus 7? 9 is the greater number. So put up 7 fingers. We count on 9, 10, 11, 12, 13, 14, 15, 16. 9 plus 7 equals 16. You can follow the same procedure in adding numbers in a vertical manner. What is the sum of 7 plus 5? 7 is the greater number. So put up 5 fingers. Let's count on 7, 8, 9, 10, 11, 12. 7 plus 5 equals 12. What is the sum of 6 plus 7? 7 is the greater number. Let's put up 6 fingers. Let's count on 7, 8, 9, 10, 11, 12, 13. 6 plus 7 equals 13. What is the sum of 3 plus 9? 9 is the bigger number. Let's put up 3 fingers. Let's count on 9, 10, 11, 12. 3 plus 9 equals 12. What is the sum of 2 plus 8? 8 is the bigger number. Put up 2 fingers. Let's count on 9, 10. 2 plus 8 equals... What is the sum of 7 plus 8? 8 is the bigger number. Put up 7 fingers. Let's count on 8, 9, 10, 11, 12, 13, 14, 15. 7 plus 8 equals 15. It's so easy, right? When you answer drills in your book, I hope that you remember what you have learned here, especially in finding sums with two-digit numbers.
