Properties of 3D Shapes Worksheet | Key Stage 1 PDF Geometry ... - Free Printable

Let's solve this step-by-step.

Section A: Name the 3D Shapes

We are given 8 images of 3D shapes and a list of names to match them with. The names are:

- Cylinder
- Cube
- Square-based pyramid
- Triangular prism
- Cuboid
- Triangular-based pyramid
- Sphere
- Cone

Now, let’s identify each shape:

1. First row, left to right:
- Blue cube: All faces are squares → Cube
- Pink rectangular box: Rectangular faces → Cuboid
- Red round ball: Smooth, no edges → Sphere
- Blue cylinder: Two circular ends, curved side → Cylinder

2. Second row, left to right:
- Orange cone: One circular base, tapers to a point → Cone
- Purple pyramid with square base: Square base, triangular sides → Square-based pyramid
- Green pyramid with triangle base: Triangle base, triangular sides → Triangular-based pyramid
- Yellow prism with two triangles and three rectangles: → Triangular prism

✔ So, matching each image:

| Shape | Name |
|------|------|
| Blue cube | Cube |
| Pink cuboid | Cuboid |
| Red sphere | Sphere |
| Blue cylinder | Cylinder |
| Orange cone | Cone |
| Purple pyramid (square base) | Square-based pyramid |
| Green pyramid (triangle base) | Triangular-based pyramid |
| Yellow prism | Triangular prism |

Section B: Match descriptions to 3D shapes

We are given a list of shapes on the left and descriptions on the right. We need to connect each shape to its correct description.

One is already done:
- Sphere → "Has one curved face and can roll in any direction"

Let’s go through each:

#### 1. Cone
- Description: "Has one flat circular face. Rolls in a circle."
- ✔ Correct — a cone has a circular base and rolls in a circle when pushed.

#### 2. Cube
- Description: "Has 6 flat faces. All of the faces are squares."
- ✔ Correct — all six faces are equal squares.

#### 3. Triangular prism
- Description: "Has two triangular faces and 3 faces that are rectangles."
- ✔ Correct — it has two triangular bases and three rectangular sides.

#### 4. Sphere
- Already matched: "Has one curved face and can roll in any direction"
- ✔ Correct — smooth, no flat faces, rolls freely.

#### 5. Square-based pyramid
- Description: "Has one square face, the others are triangles."
- ✔ Correct — base is square, four triangular faces meet at apex.

#### 6. Cuboid
- Description: "Has 6 flat faces. All of them are rectangles."
- ✔ Correct — like a box, all faces are rectangles (can be different sizes).

#### 7. Triangular-based pyramid
- Description: "Has 4 flat faces. All of the faces are triangles."
- ✔ Correct — also known as a tetrahedron; all four faces are triangles.

#### 8. Cylinder
- Description: "Has two flat circular faces and one curved face. Will roll in a straight line."
- ✔ Correct — two circular ends, curved surface, rolls straight.

Section B: Matching Descriptions

| Shape | Description |
|-------|-------------|
| 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. |
| Cuboid | 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. |

✔ Summary

This worksheet helps students understand the properties of common 3D shapes by matching visual representations and descriptive features. Key concepts include:
- Number and type of faces
- Whether faces are flat or curved
- How the shape rolls
- Base shape (e.g., square, triangle, circle)

These skills build foundational geometry knowledge for later math topics.
