The task involves writing an addition sentence for each array shown in the image. An
array is a way of organizing objects into rows and columns, and the total number of objects can be found by adding the number of objects in each row.
Let's solve each part step by step:
---
Array A:
- The array has
3 rows and
5 columns.
- Each row contains 5 pumpkins.
- Total number of pumpkins = \( 5 + 5 + 5 \).
Addition sentence:
\[ 5 + 5 + 5 = 15 \]
---
Array B:
- The array has
4 rows and
2 columns.
- Each row contains 2 bats.
- Total number of bats = \( 2 + 2 + 2 + 2 \).
Addition sentence:
\[ 2 + 2 + 2 + 2 = 8 \]
---
Array C:
- The array has
2 rows and
4 columns.
- Each row contains 4 owls.
- Total number of owls = \( 4 + 4 \).
Addition sentence:
\[ 4 + 4 = 8 \]
---
Array D:
- The array has
3 rows and
3 columns.
- Each row contains 3 pumpkins.
- Total number of pumpkins = \( 3 + 3 + 3 \).
Addition sentence:
\[ 3 + 3 + 3 = 9 \]
---
Array E:
- The array has
2 rows and
2 columns.
- Each row contains 2 pots of candy.
- Total number of pots of candy = \( 2 + 2 \).
Addition sentence:
\[ 2 + 2 = 4 \]
---
Array F:
- The array has
4 rows and
4 columns.
- Each row contains 4 spiders.
- Total number of spiders = \( 4 + 4 + 4 + 4 \).
Addition sentence:
\[ 4 + 4 + 4 + 4 = 16 \]
---
Final Answers:
\[
\boxed{
\begin{aligned}
&\text{A: } 5 + 5 + 5 = 15 \\
&\text{B: } 2 + 2 + 2 + 2 = 8 \\
&\text{C: } 4 + 4 = 8 \\
&\text{D: } 3 + 3 + 3 = 9 \\
&\text{E: } 2 + 2 = 4 \\
&\text{F: } 4 + 4 + 4 + 4 = 16
\end{aligned}
}
