Basic Two Dimensional Shapes for Kids

An Introduction to Two Dimensional Shapes in Year 1

Two-dimensional shapes are those shapes that have only two dimensions such as length and width. They are flat shapes. Two-dimensional shapes are also written as 2D. Examples of 2D shapes include circles, squares, rectangles, triangles, etc.

For better understanding, we have given an example below for 2-D shapes year 1. It is a rectangle that has two dimensions, which are length and width. It is a flat shape. So it is clearly a two-dimensional shape.

2-D Shapes and Their Properties

Some important 2-D shapes that kids should know and their properties are given below.

A circle is a 2-D shape that is made up of a curved line. Each point present on the curved line is placed at an equal distance from its centre. So circles are completely round in shape.



A triangle is a shape having three sides. There are different types of triangles such as equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene. You will learn about types of triangles in higher classes.



A square is a shape having 4 sides of equal length.



A rectangle is a shape whose opposite sides are of equal length.


Kids are familiar with the most common shapes before going to school because they see them in daily life. The above article discusses all the basic shapes in Year 1 that a kid needs to know. Parents and teachers can also read the article as it will be helpful for them to teach 2-D shapes to their children.

FAQs on Basic Two Dimensional Shapes for Kids

1. When do children learn about 2-D shapes?

Children see different two-dimensional shapes in daily life. After seeing these shapes, they might ask their parents about the name of such 2D shapes and identify them. Parents and teachers need to cater to their curiosity. When children go to school, shapes in Year 1 are introduced with some fun activities like the colouring of shapes, drawing different shapes, cutting papers of shapes, etc. so that kids learn about 2-D shapes easily and can memorise them.

2. What are the 2-D shapes that should be taught to a kid in Year 1?

Kids should be familiar with some basic shapes such as circles, squares, rectangles, triangles and other 2-D shapes in Year 1. They should be able to identify these shapes. Parents should teach them the properties of 2-D shapes in an engaging way. They should initiate some interesting activities to impart knowledge with fun to ensure their children not only enjoy learning but also retain what they have learnt and recall when required.
