- The development of spatial sense enables students to solve problems involving 3-D objects and 2-D shapes. Spatial sense offers a way to interpret and reflect on the physical environment and its 3-D or 2-D representations.

- Head Off On a Shape Hunt. A great way to kick start learning about shapes (whether it be at school or home) is with a ‘shape hunt’ – exploring and identifying shapes in our environment and everyday life.
- Popstick Play. Popsticks and matchsticks are such versatile learning materials. They make a great resource for creating 2D shapes.
- Self Correcting Popstick Puzzle. Take the above activity one step further and make a self correcting puzzle by using the one colour for each shape, writing the name of the shape on each popstick and including the number of sides/corners.
- Pipe Cleaner Creations. Pipe cleaners provide a great workout for finger muscles. They can be bent and twisted to create a variety of 2D shapes. As a variation, make the shapes larger by using one pipe cleaner for each side of the shape.
In this video, children will learn how to identify the traits of common 2D and 3D shapes and how to differentiate them....more.

In geometry, a shape or a figure that has a length and a breadth is a 2D shape. In other words, a plane object that has only length and breadth is 2 dimensional. Straight or curved lines make up the sides of this shape. Also, these figures can have any number of sides. In general, plane figures made of lines are known as polygons. For example, tria...
2D shapes are further classified into 2 types – regular or irregular – based on their length and interior angles. 1. A 2D shape is considered to be regular if all of its sides have the same length and all of its interior angles are of the same measurement. 2. A 2D shape is irregular if all of its sides are unequal in length and all of its angles ar...
Regular and irregular 2D shapes include the circle, triangle, square, rectangle, pentagon, and hexagon. Let us look at a few of them and their properties. Circles are entirely round shapes formed by a single curved line. The curved line’s points are at equal distances from its centre. A semi-circle has two sides, one curved and one straight. The en...
A three-dimensional shape is defined in geometry as a solid figure or an item or shape with three dimensions — length, breadth, and height. In our day to day life, we see several objects around us which have different shapes. For example, books, balls, ice-cream cones etc. One thing common in these objects is that they all have some length, breadth...
In mathematics and real life, there are many 3D shapes and objects with different bases, surface areas and volumes. Let us look at a few of the most commonly seen 3D shapes. 1. A sphere is round and circular in shape. All the points on the surface of the sphere are equidistant from the centre. It has the following dimensions: radius, diameter, circ...
Every three-dimensional shape has a surface area and a volume metric. The surface area is the area occupied by the 3D shape at the bottom, top, and all faces, including any curved surfaces. A 3D shape’s volume is defined as the amount of space it takes up.
Let us take an example. The object below is a cube. The corners of the cube are its vertices. The 12 line segments that form the skeleton of the cube are its edges. The 6 flat square surfaces that are the skin of the cube are its faces. Observe that the two-dimensional figures can be identified as the faces of the three-dimensional shapes. For exam...
A net is a two-dimensional representation of a three-dimensional figure that is unfolded along its edges. It represents each face of the figure in two dimensions. In other words, a net is a pattern made when the surface of a three-dimensional figure is laid out. Thus showing each face of the figure. A solid may have different nets. For example, a b...
Question 1: Which of the following is true for a polyhedron? 1. Polyhedrons are 3D figures. 2. They always have a closed surface. 3. A line joining any two points on the surface always lies inside the shape. 4. Both bases are parallel to each other. Answer :(i) and (ii) are true. Question 2: What are 2D shapes? Answer:2D shapes refer to all those s...
A shape is 2D if it is flat. 2D means it has two dimensions: length and breadth. or. length and height. 2D shapes include circle, triangle, square, rectangle. pentagon, hexagon.
Learning how to identify two and three dimensional shapes is a second grade, Common Core math skill: 2.G.1. Below we show three videos that demonstrate this standard. Then, we provide a breakdown of the specific steps in the videos to help you teach your class. Prior Learnings.
What does 2D and 3D mean? Students begin by learning about the properties of ‘flat’, 2D (or two-dimensional) shapes, including polygons. These shapes can be drawn using straight lines on paper with just two dimensions; for example, length and width.
Aug 6, 2024 · Here we provide a summary of the 2D shapes and 3D shapes covered in the maths curriculum at primary school with a specific focus on the properties of shapes that teachers and parents can support children to learn and understand.
