Properties of 3D Shapes worksheet for students to identify and match 3D shapes with their names and descriptions.

Explanation:
Let’s solve Section A and Section B step by step.

Section A: Name the 3D shapes

We have 8 shapes in a grid. The possible names are:
Cylinder, Cube, Square-based pyramid, Triangular prism, Rectangular Prism, Triangular-based pyramid, Sphere, Cone.

Match each shape:

1. First shape (top-left): Blue, all sides equal, 6 square faces → Cube

2. Second shape (top row, second): Pink, rectangular faces, looks like a box → Rectangular Prism

3. Third shape (top row, third): Red, perfectly round, no flat faces → Sphere

4. Fourth shape (top row, fourth): Blue, two circular ends + curved side - rolls straight → Cylinder

5. Fifth shape (second row, first): Orange, pointy top, circular base, curved side → Cone

6. Sixth shape (second row, second): Purple, square base + 4 triangular faces meeting at a point → Square-based pyramid

7. Seventh shape (second row, third): Green, 4 triangular faces (looks like a tetrahedron) → Triangular-based pyramid

8. Eighth shape (second row, fourth): Yellow, two triangular bases + 3 rectangular sides → Triangular prism

So the matches for Section A are:
- Cube
- Rectangular Prism
- Sphere
- Cylinder
- Cone
- Square-based pyramid
- Triangular-based pyramid
- Triangular prism

Now Section B: Match descriptions to names

We’re given 8 shape names on the left and 8 descriptions on the right. One match is already done (Cone → “Has one curved face and can roll in any direction” — but wait! Let’s double-check that.)

Actually, looking carefully: the orange line connects Sphere (not Cone) to the description: *“Has one curved face and can roll in any direction.”*
But that’s incorrect — a sphere has *one curved surface* (no flat faces), and it *rolls in any direction*. That description fits Sphere, not Cone.

Wait — let’s read the descriptions again carefully:

Descriptions (right column):
1. Has one curved face and can roll in any direction. → ✔ Sphere
2. Has two flat circular faces and one curved face. Will roll in a straight line. → ✔ Cylinder
3. Has 6 flat faces. All of them are rectangles. → ✔ Rectangular Prism
4. Has one flat circular face. Rolls in a circle. → ✔ Cone
5. Has 6 flat faces. All of the faces are squares. → ✔ Cube
6. Has 4 flat faces. All of the faces are triangles. → ✔ Triangular-based pyramid
7. Has two triangular faces and 3 faces that are rectangles. → ✔ Triangular prism
8. Has one square face, the others are triangles. → ✔ Square-based pyramid

Now match left column:

Left column order:
- Cone → matches description 4
- Cube → description 5
- Triangular prism → description 7
- Sphere → description 1
- Square-based pyramid → description 8
- Rectangular Prism → description 3
- Triangular-based pyramid → description 6
- Cylinder → description 2

Let’s verify each:

- Cone: 1 circular base (flat), 1 curved surface → rolls in a circle → ✔️ description 4
- Cube: 6 square faces → ✔️ description 5
- Triangular prism: 2 triangular bases + 3 rectangular sides → ✔️ description 7
- Sphere: fully curved, no edges, rolls freely → ✔️ description 1
- Square-based pyramid: 1 square base + 4 triangular faces → ✔️ description 8
- Rectangular Prism: 6 rectangular faces → ✔️ description 3
- Triangular-based pyramid (tetrahedron): 4 triangular faces → ✔️ description 6
- Cylinder: 2 circular flat faces + 1 curved face, rolls straight → ✔️ description 2

All match correctly.

So final answers:

Section A (top to bottom, left to right):
1. Cube
2. Rectangular Prism
3. Sphere
4. Cylinder
5. Cone
6. Square-based pyramid
7. Triangular-based pyramid
8. Triangular prism

Section B matching:
Cone → “Has one flat circular face. Rolls in a circle.”
Cube → “Has 6 flat faces. All of the faces are squares.”
Triangular prism → “Has two triangular faces and 3 faces that are rectangles.”
Sphere → “Has one curved face and can roll in any direction.”
Square-based pyramid → “Has one square face, the others are triangles.”
Rectangular Prism → “Has 6 flat faces. All of them are rectangles.”
Triangular-based pyramid → “Has 4 flat faces. All of the faces are triangles.”
Cylinder → “Has two flat circular faces and one curved face. Will roll in a straight line.”

Since the question asks to solve the problem (and only wants the final answer), we provide the completed matching as the answer.

Final Answer:
Section A (left to right, top to bottom): Cube, Rectangular Prism, Sphere, Cylinder, Cone, Square-based pyramid, Triangular-based pyramid, Triangular prism
Section B matches:
Cone → Has one flat circular face. Rolls in a circle.
Cube → Has 6 flat faces. All of the faces are squares.
Triangular prism → Has two triangular faces and 3 faces that are rectangles.
Sphere → Has one curved face and can roll in any direction.
Square-based pyramid → Has one square face, the others are triangles.
Rectangular Prism → Has 6 flat faces. All of them are rectangles.
Triangular-based pyramid → Has 4 flat faces. All of the faces are triangles.
Cylinder → Has two flat circular faces and one curved face. Will roll in a straight line.
