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.

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.

The thin plastic shapes that are sometimes used to represent common 2D shapes are actually 3D because they do have depth to them – even if it’s very small.Īs well as the names, children need to know the properties of 2D shapes as listed below and in the printable table. Examples of dimensions include length, width or breadth, depth and height. What does 2D mean?ĢD in 2D shapes stands for 2-dimensional. We normally talk about dimensions as measurements in a direction. 2D shapes are flat and cannot be physically held, because they have no depth a 2D shape is completely flat. An example of a 2D shape is a rectangle or a circle. Let’s kick off with some definitions! What are 2D shapes?ĢD shapes are shapes with two dimensions, such as width and height.

We also look at the properties of 2D shape that children are expected to know. We cover the the two-dimensional shapes children will need to have mastered in each year group from the familiar such as squares and triangles to the less familiar polygons. Children start learning about 2D shapes from as early as year 1 in primary school, so here is everything you need to know to support them.
