Educational worksheet for students to practice drawing 2D views of 3D shapes constructed from cubes.

To solve the problem of drawing the front view (FV), side view (SV), and top view (TV) for each 3D shape, we need to carefully analyze the arrangement of cubes in each 3D diagram. Here's a step-by-step explanation for each shape:

---

Shape 1 (Top Row, Leftmost):

- Front View (FV): The front view shows the number of cubes visible from the front. There are 2 columns: the left column has 2 cubes stacked vertically, and the right column has 1 cube.
- FV:
```
XX
X
```
- Side View (SV): The side view shows the number of cubes visible from the side. There are 2 rows: the top row has 1 cube, and the bottom row has 2 cubes.
- SV:
```
X
XX
```
- Top View (TV): The top view shows the number of cubes visible from above. There are 2 cubes in a row.
- TV:
```
XX
```

Shape 2 (Second Row, Leftmost):

- Front View (FV): The front view shows 3 cubes stacked vertically.
- FV:
```
X
X
X
```
- Side View (SV): The side view shows 3 cubes stacked vertically.
- SV:
```
X
X
X
```
- Top View (TV): The top view shows 1 cube.
- TV:
```
X
```

---

Shape 3 (Third Row, Leftmost):

- Front View (FV): The front view shows 4 cubes in a single row.
- FV:
```
XXXX
```
- Side View (SV): The side view shows 2 cubes stacked vertically.
- SV:
```
X
X
```
- Top View (TV): The top view shows 4 cubes in a single row.
- TV:
```
XXXX
```

---

Shape 4 (Bottom Row, Leftmost):

- Front View (FV): The front view shows 3 cubes in a row, with the middle cube being taller (3 cubes high).
- FV:
```
X
XX
X
```
- Side View (SV): The side view shows 3 cubes stacked vertically.
- SV:
```
X
X
X
```
- Top View (TV): The top view shows 3 cubes in a row.
- TV:
```
XXX
```

Final Answer:

Here is the completed table with all views:

| 3D Diagram | Front View (FV) | Side View (SV) | Top View (TV) |
|------------|------------------|----------------|---------------|
| Shape 1 | ```XX<br>X``` | ```X<br>XX``` | ```XX``` |
| Shape 2 | ```X<br>X<br>X``` | ```X<br>X<br>X``` | ```X``` |
| Shape 3 | ```XXXX``` | ```X<br>X``` | ```XXXX``` |
| Shape 4 | ```X<br>XX<br>X``` | ```X<br>X<br>X``` | ```XXX``` |

Thus, the final answer is:

\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{3D Diagram} & \text{Front View (FV)} & \text{Side View (SV)} & \text{Top View (TV)} \\
\hline
\text{Shape 1} & \begin{array}{c}XX \\ X\end{array} & \begin{array}{c}X \\ XX\end{array} & \begin{array}{c}XX\end{array} \\
\hline
\text{Shape 2} & \begin{array}{c}X \\ X \\ X\end{array} & \begin{array}{c}X \\ X \\ X\end{array} & \begin{array}{c}X\end{array} \\
\hline
\text{Shape 3} & \begin{array}{c}XXXX\end{array} & \begin{array}{c}X \\ X\end{array} & \begin{array}{c}XXXX\end{array} \\
\hline
\text{Shape 4} & \begin{array}{c}X \\ XX \\ X\end{array} & \begin{array}{c}X \\ X \\ X\end{array} & \begin{array}{c}XXX\end{array} \\
\hline
\end{array}
