Educational worksheet teaching students to identify shapes based on the number of sides.

To solve the problem, we need to identify each shape based on the number of sides it has. Let's go through each shape step by step:

Shapes and Their Names:

1. Triangle: A shape with 3 sides.
2. Quadrilateral: A shape with 4 sides.
3. Pentagon: A shape with 5 sides.
4. Hexagon: A shape with 6 sides.

Identifying Each Shape:

#### Row 1:
- Shape 1: This shape has 5 sides.
Answer: Pentagon
- Shape 2: This shape has 3 sides.
Answer: Triangle

#### Row 2:
- Shape 3: This shape has 4 sides.
Answer: Quadrilateral (specifically a trapezoid)
- Shape 4: This shape has 6 sides.
Answer: Hexagon

#### Row 3:
- Shape 5: This shape has 3 sides.
Answer: Triangle
- Shape 6: This shape has 4 sides.
Answer: Quadrilateral (specifically a square)

#### Row 4:
- Shape 7: This shape has 4 sides.
Answer: Quadrilateral (specifically a parallelogram)
- Shape 8: This shape has 4 sides.
Answer: Quadrilateral (specifically a rhombus)

#### Row 5:
- Shape 9: This shape has 4 sides.
Answer: Quadrilateral (specifically a rectangle)
- Shape 10: This shape has 5 sides.
Answer: Pentagon

Final Answer:

\[
\begin{array}{cc}
\text{Pentagon} & \text{Triangle} \\
\text{Quadrilateral (trapezoid)} & \text{Hexagon} \\
\text{Triangle} & \text{Quadrilateral (square)} \\
\text{Quadrilateral (parallelogram)} & \text{Quadrilateral (rhombus)} \\
\text{Quadrilateral (rectangle)} & \text{Pentagon} \\
\end{array}
\]

Thus, the completed worksheet looks like this:

\[
\boxed{
\begin{array}{cc}
\text{Pentagon} & \text{Triangle} \\
\text{Quadrilateral} & \text{Hexagon} \\
\text{Triangle} & \text{Square} \\
\text{Parallelogram} & \text{Rhombus} \\
\text{Rectangle} & \text{Pentagon} \\
\end{array}
}
\]
