Year 1 Shapes - 2D
Triangles, circles and squares are three of the most common 2-dimensional shapes.

Year 1 Shapes - 2D

Spot 2D shapes in everyday objects. Learn sides and corners, and name squares, rectangles, circles, and triangles by looking, tracing, and sorting.

Fascinating Fact:

A rectangle has 4 corners and 2 long sides and 2 short sides, like a book cover or a door.

In KS1 Maths, children learn to recognise, name, and describe 2D shapes. Pupils talk about the number of sides and corners, sort shapes by features, and find examples in real life.

  • 2D shape: A flat shape you can draw on paper, like a circle or square.
  • Side: A straight edge of a shape, such as one edge of a triangle.
  • Corner (vertex): The point where two sides meet.

Warm up with a quick practice: play the Numeracy Game to order and compare numbers before starting the quiz.

What are 2D shapes for Year 1?

2D shapes are flat shapes like circles, triangles, squares, and rectangles. Children learn to name them and describe their sides and corners.

How can I teach sides and corners to KS1 pupils?

Trace shapes with a finger, count sides and corners aloud, and sort classroom items by shape. Use simple language and lots of real examples.

What is the difference between a square and a rectangle?

A square has four equal sides and four corners. A rectangle also has four corners, but opposite sides are equal, not all four.
