Pupils identify, compare and sort shapes on the basis of their properties and use vocabulary precisely, such as sides, edges, vertices and faces.

Non-statutory guidance: Pupils handle and name a wide variety of common 2-D and 3-D shapes, including quadrilaterals and polygons, and cuboids, prisms and cones, and identify the properties of each shape (for example, number of sides, number of faces).

Compare and sort common 2-D and 3-D shapes and everyday objects.

Identify 2-D shapes on the surface of 3-D shapes,.

Identify and describe the properties of 3-D shapes, including the number of edges, vertices and faces.

Identify and describe the properties of 2-D shapes, including the number of sides and line symmetry in a vertical line.

They recognise these shapes in different orientations and sizes, and know that rectangles, triangles, cuboids and pyramids are not always similar to each other.

Non-statutory guidance: Pupils handle common 2-D and 3-D shapes, naming these and related everyday objects fluently.

Recognise and name common 2-D and 3-D shapes, including: 2-D shapes 3-D shapes.

Here’s what the National Curriculum expects to be taught about 2D shapes: 2D shapes in Year 1 Geometry is taught in every year group in KS1 and KS2. Read more: 2D And 3D Shapes: Properties of Shapes When do children learn about 2D shapes in primary school?

A heptagon or septagon is any shape with 7 sides.

A parallelogram has two pairs of parallel lines and opposite equal angles.

A trapezium has one pair of parallel lines.

A rhombus has two pairs of parallel lines, as well as equal sides and opposite equal angles.

A rectangle has two pairs of parallel straight lines and each angle equals 90°.A kite has two pairs of equal-length sides and the diagonals cross at right-angles.A square is a regular quadrilateral and each angle equals 90°.An isosceles triangle has two sides and two angles that are the same.A scalene triangle is an irregular triangle.A right-angled triangle is any triangle with one right angle.An equilateral triangle is a regular triangle and each angle equals 60°.A semi-circle has 2 sides 1 curved side and 1 straight side.Learning 2D shapes through Third Space Learning’s online interventions Properties of 2D shapesĪs well as the names, children need to know the properties of 2D shapes as listed below and in the printable table. When we move on to 3D shapes we talk about faces, edges and vertices. The properties of 2D shapes refer to their sides and angles. An irregular shape has different length sides and/or interior angles.A regular shape has all sides the same length and all interior angles the same size.

A polygon is a 2D shape with straight sides.In primary school, children will learn about the following 2d shapes: polygons, regular and irregular shapes.

For example, if the length is measured in feet, and the width is measured in inches, you must make sure to convert the length to inches, or the width to feet.Download Free Now! Which 2D shapes do children learn about? You need to make sure that the units you are using are the same for both sides, otherwise the area will be incorrect. The area of the rectangle is 28 units squared. If we have a rectangle with a length of 7 and a width of 4, we can calculate the area by plugging in the numbers: Simply take the length of the rectangle and multiply it by the width. The area of the square is 9 units squared.įor a rectangle, the approach is similar to that of a square. So, if we have a square with a side length of 3, we would do the following calculation: Find the length of one side, multiply it by itself, and you have the area. Since all four sides are the same, length and width are the same value. The simplest shape to calculate the area of is a square. However, the general rule is:Īrea = Length × Width ext Area = Length × Width Calculating the area of a 2D shape depends on what shape you have.
