Question 4.
Write a number bond in each number sentence to show how to make ten.

a. 9 + 5 = 14

b. 8 + 5 = 13

c. 6 + 9 = 15

d. 17 = 8 + 9

Explanation:
a. In the above image we can observe 9 + 5 = 14  number sentence . In that five is divided into two parts. One is four and another one is one. A number bond is a simple addition of two numbers that add up to give the sum. ADD one with nine then we got ten. By adding ten with four results fourteen.
b. In the above image we can observe 8 + 5 = 13  number sentence . In that five is divided into two parts. One is three and another one is two. A number bond is a simple addition of two numbers that add up to give the sum. ADD two with eight then we got ten. By adding ten with three results thirteen.
c. In the above image we can observe 6 + 9 = 15  number sentence . In that six is divided into two parts. One is five and another one is one. A number bond is a simple addition of two numbers that add up to give the sum. ADD one with nine then we got ten. By adding ten with five results fifteen.
d. In the above image we can observe17 = 8 + 9  number sentence . In that eight is divided into two parts. One is seven and another one is one. A number bond is a simple addition of two numbers that add up to give the sum. ADD one with nine then we got ten. By adding ten with seven results seventeen.
