Question

1. circle the larger part.

count on.
fill in the number bond.
1 2 3 4 5 6 7 8 9 10
5 + 3 =
3 + 5 =
number bond diagram
7 + 2 =
2 + 7 =
another number bond diagram
2 + 8 =
third number bond diagram

Explanation:

Step1: Calculate \(5 + 3\)

Add 5 and 3: \(5 + 3 = 8\)

Step2: Calculate \(3 + 5\)

Add 3 and 5 (commutative property): \(3 + 5 = 8\)

Step3: Calculate \(7 + 2\)

Add 7 and 2: \(7 + 2 = 9\)

Step4: Calculate \(2 + 7\)

Add 2 and 7 (commutative property): \(2 + 7 = 9\)

Step5: Calculate \(2 + 8\)

Add 2 and 8: \(2 + 8 = 10\)

For the number bonds:

• For \(5 + 3\) and \(3 + 5\), the parts are 5, 3, and the whole is 8.
• For \(7 + 2\) and \(2 + 7\), the parts are 7, 2, and the whole is 9.
• For \(2 + 8\), the parts are 2, 8, and the whole is 10.

Answer:

• \(5 + 3 = \boldsymbol{8}\), Number bond: parts 5, 3; whole 8.
• \(3 + 5 = \boldsymbol{8}\), Number bond: parts 3, 5; whole 8.
• \(7 + 2 = \boldsymbol{9}\), Number bond: parts 7, 2; whole 9.
• \(2 + 7 = \boldsymbol{9}\), Number bond: parts 2, 7; whole 9.
• \(2 + 8 = \boldsymbol{10}\), Number bond: parts 2, 8; whole 10.
