How to teach 2D shapes
- Teach the names. Teach the names of the shapes.
- Teach what makes a shape unique. Teach the unique characteristics of each shape.
- Teach what makes a 2D shape a 2D shape. Teach what makes the circle, square, triangle rectangle and hexagon all 2D shapes in a simplified fashion.
- Teach shapes in the world.
What is the meaning of 2D shapes?
2-dimensional
Definition. 2D stands for 2-dimensional. 2-dimensional shapes are flat and only have two dimensions: length and width. They include squares, rectangles, circles, triangles, and more.
Why is knowing 2D shapes important?
Learning 2D shapes is key for future math learning. If students don’t recognize 2D shapes, they won’t be able to recognize 3D shapes and will not be able to handle geometry. Knowing 2D shapes is also important for measurement, as students who can’t recognize a rectangle won’t be able to measure it correctly.

How do you explain 2D shapes to kindergarten?
2D shapes are shapes with two dimensions, such as width and height. An example of a 2D shape is a rectangle or a circle. 2D shapes are flat and cannot be physically held, because they have no depth; a 2D shape is completely flat.
What are properties of 2D shapes?
A 2D shape is a flat shape with sides, vertices and sometimes lines of symmetry. If the sides and vertices on a shape are all the same, the shape is regular.
How do you identify 2D shapes?
A two-dimensional (2D) shape has only two measurements, such as length and height. A square, triangle, and circle are all examples of a 2D shape. However, a three-dimensional (3D) shape has three measurements, such as length, width, and height.
Why do we need to know shapes?
Learning shapes not only helps children identify and organize visual information, it helps them learn skills in other curriculum areas including reading, math, and science. Learning shapes also helps children understand other signs and symbols. A fun way to help your child learn shapes is to make a shape hunt game.

A triangle is a three-sided polygon (2d Shape) which has three edges and three vertices. Square. Rectangle. Pentagon. Octagon. 2D Shapes Properties. 2d Shapes and 3d Shapes.
What 2D shape has eight sides?
Regular Polygons. A polygon is a plane (2D) shape with straight sides. To be a regular polygon all the sides and angles must be the same: Triangle – 3 Sides. Square – 4 Sides. Pentagon – 5 Sides. Hexagon – 6 sides. Heptagon – 7 Sides. Octagon – 8 Sides.
