2D Shapes — Year 1 Lesson Plan
National Curriculum: Mathematics — Geometry: properties of shapes — recognise and name common 2D shapes, Year 1
Overview
Pupils recognise, name, and describe common 2D shapes including circles, triangles, squares, and rectangles. They explore the properties of these shapes — including the number of sides and corners — and learn to sort and identify shapes in different orientations and sizes.
Learning Objectives
- Recognise and name common 2D shapes: circle, triangle, square, rectangle, pentagon, hexagon.
- Describe shapes using the properties of sides and corners (vertices).
- Identify 2D shapes in different sizes and orientations.
- Sort shapes according to their properties.
Key Vocabulary
Suggested Lesson Structure
Place a range of 2D shapes in a feely bag. Pupil puts hand in and describes what they can feel — how many sides, are they straight? Class guesses the shape before it is revealed.
Display common 2D shapes and name each. Count sides and corners together. Establish that a square is a special type of rectangle (all sides equal). Show shapes in different orientations — a triangle pointing down is still a triangle. Sort shapes by number of sides.
Pupils sort a set of shape cards by number of sides. Then complete a shape property table: name, number of sides, number of corners. Include regular and irregular examples (e.g. a non-equilateral triangle).
Pupils go on a shape hunt around the classroom or using a picture, recording each shape they find and its name. Then draw two different triangles and explain what makes them both triangles.
True or false: 'A square is a rectangle.' Pupils discuss in pairs, then share reasoning. Establish: yes, a square is a rectangle — but not all rectangles are squares.
Common Misconceptions
- Pupils recognise only 'standard' orientations — a triangle with a flat base but not one pointing down. Use varied examples.
- Thinking a square and a rectangle are entirely different shapes — address the relationship explicitly.
Prior Knowledge
Pupils should already be able to:
- Familiarity with circle, square, and triangle from the EYFS.
- Ability to count sides on simple shapes.
