Question 1:

William has 136 crayons in his pencil box. Phillip has 148 crayons in his pencil box. How many crayons do William and Phillip have altogether?

#### Solution:
1. Add the numbers: \( 136 + 148 \).
2. Perform the addition step by step:
- Add the units place: \( 6 + 8 = 14 \). Write down 4 and carry over 1.
- Add the tens place: \( 3 + 4 + 1 \) (carry-over) \( = 8 \).
- Add the hundreds place: \( 1 + 1 = 2 \).

So, \( 136 + 148 = 284 \).

#### Answer:
\[ \boxed{B} \]

Question 2:

Josie plants 137 flowers in her backyard. Lena gives her 58 more flowers to plant in her backyard. How many flowers does Josie have now?

#### Solution:
1. Add the numbers: \( 137 + 58 \).
2. Perform the addition step by step:
- Add the units place: \( 7 + 8 = 15 \). Write down 5 and carry over 1.
- Add the tens place: \( 3 + 5 + 1 \) (carry-over) \( = 9 \).
- Add the hundreds place: \( 1 + 0 = 1 \).

So, \( 137 + 58 = 195 \).

#### Answer:
\[ \boxed{A} \]

Question 3:

Charles finds 129 seashells at the beach. Phillip finds 46 seashells at the beach. How many seashells do Charles and Phillip find at the beach together?

#### Solution:
1. Add the numbers: \( 129 + 46 \).
2. Perform the addition step by step:
- Add the units place: \( 9 + 6 = 15 \). Write down 5 and carry over 1.
- Add the tens place: \( 2 + 4 + 1 \) (carry-over) \( = 7 \).
- Add the hundreds place: \( 1 + 0 = 1 \).

So, \( 129 + 46 = 175 \).

#### Answer:
\[ \boxed{C} \]

Question 4:

Lily has 162 gumballs and 155 jellybeans. How many pieces of candy does Lily have?

#### Solution:
1. Add the numbers: \( 162 + 155 \).
2. Perform the addition step by step:
- Add the units place: \( 2 + 5 = 7 \).
- Add the tens place: \( 6 + 5 = 11 \). Write down 1 and carry over 1.
- Add the hundreds place: \( 1 + 1 + 1 \) (carry-over) \( = 3 \).

So, \( 162 + 155 = 317 \).

#### Answer:
\[ \boxed{B} \]

Question 5:

Mrs. Jones caught 63 banana moon pies and 28 chocolate moon pies at Mardi Gras. How many moon pies did she catch in all?

#### Solution:
1. Add the numbers: \( 63 + 28 \).
2. Perform the addition step by step:
- Add the units place: \( 3 + 8 = 11 \). Write down 1 and carry over 1.
- Add the tens place: \( 6 + 2 + 1 \) (carry-over) \( = 9 \).

So, \( 63 + 28 = 91 \).

#### Answer:
\[ \boxed{C} \]

Question 6:

Mrs. White made 115 round cookies and 176 square cookies. How many cookies did Mrs. White have ready for the bake sale at school?

#### Solution:
1. Add the numbers: \( 115 + 176 \).
2. Perform the addition step by step:
- Add the units place: \( 5 + 6 = 11 \). Write down 1 and carry over 1.
- Add the tens place: \( 1 + 7 + 1 \) (carry-over) \( = 9 \).
- Add the hundreds place: \( 1 + 1 = 2 \).

So, \( 115 + 176 = 291 \).

#### Answer:
\[ \boxed{A} \]
