2 + 8
= 10.
3 + 7
= 10.
4 + 6
= 10.
5 + 5
= 10.
2. Addition fact sums of 11:
0 +
11 = 11.
1 +
10 = 11.
2 + 9
= 11.
3 + 8
= 11.
4 + 7
= 11.
5 + 6
= 11.
3. Addition fact sums of 12:

1 +
11 = 12.
2 +
10 = 12.
3 + 9
= 12.
4 + 8
= 12.
5 + 7
= 12.
6 + 6

= 13.
6 + 7
= 13.
5. Addition fact sums of 14:
0 +
14 = 14.
1 +
13 = 14.
2 +
12 = 14.
3 +
11 = 14.
4 +

5 + 9
= 14.
6 + 8
= 14.
7 + 7
= 14.
6. Addition fact sums of 15:
0 +
15 = 15.
1 +
14 = 15.
2 +
13 = 15.
3 +
12 = 15.
4 +
11 = 15.
5 +
10 = 15.
6 + 9
= 15.
7 + 8
= 15.
7. Add: 6 + 5 = ?
Solution:
Start
counting from the number after 6 and count up 5 steps: 7, 8, 9, 10, 11. At last, we get 11 in counting steps.
So, 6
+ 5 = 11.
8. Add: 6 + 8 = ?
Solution:
Start
counting from the number after 6 and count up 8 steps: 7, 8, 9, 10, 11, 12, 13,
14. At last, we get 14 in counting steps.
So, 6
+ 8 = 14.
9. 10 + 3 = ?
Solution:
Start
counting from the number after 10 and count up 3 steps: 11, 12, 13. At last, we
get 13 in counting steps.
So,
10 + 3 = 13.
10. 6 + 6 = ?
Solution:
Start
counting from the number after 6 and count up 6 steps: 7, 8, 9, 10, 11, 12. At
last, we get 12 in counting steps.
So, 6
+ 6 = 12.
11. 12 = 7 + ?
Solution:
Start
counting from the number after 7 and count up the steps to reach 12: 8, 9,
10, 11, 12. Here total steps = 5.
So,
12 = 7 + 5.
12. 19 = 16 + ?
Solution:
Start
counting from the number after 16 and count up the steps to reach 19: 17, 18,
19. Here total steps = 3.
So,
19 = 16 + 3.
