Shapes 3-Dimensional Shapes for Class 1 Maths
This discussion is about the most common 3- dimensional shapes present in the surroundings. 3- d shapes are solid figures. This concept will help the learners to identify the 3-d shapes with their names.
In this learning concept, the student will learn about
- what is a 3 -dimensional shape
- 2 and 3-dimensional shapes
- cone shape
- cube shape
- cuboid shape
- cylinder
Each concept is explained to class 1 maths students with examples and illustrations, and a mind map is added at the end to summarize the idea. Two printable worksheets with solutions of 3-D shapes are attached at the end of the page for the students to practice. Download the worksheet to test your knowledge.
According to dimensions, there are two types of shapes:
1.Two-dimensional shapes (2-D shapes)
2.Three-dimensional shapes (3-D shapes)
We have learned about 2-D shapes. Now let’s learn about 3-D shapes.
What Is a 3-Dimensional Shape
- 3-D means ‘Three-dimensional’.
- 3-D shapes or Three-dimensional shapes are solid figure or objector shape that has three dimensions – length, width, height.
- 3-D shapes have thickness.
- 2-D shapes are flat when drawing it on paper.
- 3-D shapes are fat not flat. 3-D shapes have thickness.
- To classify 3-D shapes we look edges, corners, faces/sides of the shapes.
There are various3-D shapes. Let’s learn about it.
Sphere:
- A sphere is a perfectly round solid shape. It has no sides, no corners. It has one curved face that goes all around.
Example:
Cube:
- A cube is a solid shape with 6 square faces and 8 corners.
Example:
strong>Cuboid
- A cuboid is a solid shape with 6 rectangular faces and 8 corners.
- Some pair of faces (not all) of a cuboid can be square.
Example:
Cone
A cone is a solid shape that has a circular bottom and it all goes around up to one point.
Example:
Cylinder
A cylinder is a solid shape with a circle on the top and a circle on the bottom. It has a smooth face all around.
Example:
