Grade 3 Maths Worksheets: Addition (3.2 Addition of 4 Digit ... - Free Printable

Problem Overview:

The task involves solving a crossword puzzle by completing addition sentences and plotting the results on the provided grid. The clues are given as addition problems, and the answers must be written in the corresponding positions on the crossword grid.

Step-by-Step Solution:

#### 1. Solve Each Addition Sentence:

We will solve each addition problem listed under "Across" and "Down."

---

Across:
1. \( 4563 + 2572 \)
\[
4563 + 2572 = 7135
\]

2. \( 5346 + 7328 \)
\[
5346 + 7328 = 12674
\]

3. \( 3679 + 4782 \)
\[
3679 + 4782 = 8461
\]

4. \( 9287 + 8577 \)
\[
9287 + 8577 = 17864
\]

5. \( 7964 + 8472 \)
\[
7964 + 8472 = 16436
\]

6. \( 4679 + 3879 \)
\[
4679 + 3879 = 8558
\]

---

Down:
1. \( 3589 + 1879 \)
\[
3589 + 1879 = 5468
\]

2. \( 2598 + 2186 \)
\[
2598 + 2186 = 4784
\]

3. \( 9986 + 9557 \)
\[
9986 + 9557 = 19543
\]

4. \( 9867 + 6515 \)
\[
9867 + 6515 = 16382
\]

---

#### 2. Plot the Answers on the Crossword Grid:

Now that we have solved all the addition problems, we will plot the answers on the crossword grid according to their respective positions (Across or Down).

- Across Clues:
- 1. \( 7135 \)
- 2. \( 12674 \)
- 3. \( 8461 \)
- 4. \( 17864 \)
- 5. \( 16436 \)
- 6. \( 8558 \)

- Down Clues:
- 1. \( 5468 \)
- 2. \( 4784 \)
- 3. \( 19543 \)
- 4. \( 16382 \)

#### 3. Fill in the Grid:

Using the solved answers, fill in the crossword grid:

- Across:
- 1. \( 7135 \)
- 2. \( 12674 \)
- 3. \( 8461 \)
- 4. \( 17864 \)
- 5. \( 16436 \)
- 6. \( 8558 \)

- Down:
- 1. \( 5468 \)
- 2. \( 4784 \)
- 3. \( 19543 \)
- 4. \( 16382 \)

Here is how the grid would look after filling in the answers:

```
1 2 3
+---+---+---+
1 | 7 | 1 | 3 |
+---+---+---+
2 | 1 | 2 | 6 |
+---+---+---+
3 | 8 | 4 | 6 |
+---+---+---+
4 | 1 | 7 | 8 |
+---+---+---+
5 | 1 | 6 | 4 |
+---+---+---+
6 | 8 | 5 | 5 |
+---+---+---+
7 | | | |
+---+---+---+
8 | | | |
+---+---+---+
9 | | | |
+---+---+---+
```

And for the Down clues:

```
1 2 3
+---+---+---+
1 | 7 | 1 | 3 |
+---+---+---+
2 | 1 | 2 | 6 |
+---+---+---+
3 | 8 | 4 | 6 |
+---+---+---+
4 | 1 | 7 | 8 |
+---+---+---+
5 | 1 | 6 | 4 |
+---+---+---+
6 | 8 | 5 | 5 |
+---+---+---+
7 | | | |
+---+---+---+
8 | | | |
+---+---+---+
9 | | | |
+---+---+---+
```

#### Final Answer:

The completed crossword grid with all answers filled in is as follows:

\[
\boxed{
\begin{array}{|c|c|c|}
\hline
7 & 1 & 3 \\
\hline
1 & 2 & 6 \\
\hline
8 & 4 & 6 \\
\hline
1 & 7 & 8 \\
\hline
1 & 6 & 4 \\
\hline
8 & 5 & 5 \\
\hline
\end{array}
}
\]

Each answer corresponds to the solved addition problems, and the grid is now complete.
