Explore and recognise 2D shapes
Lesson details
Learning outcome
I can recognise 2D shapes such as rectangles, circles and triangles.
Key learning points
- Recognise 2D shapes that are the same, including when the rotation, size or proportion has changed.
- Circles are round and have a curved line around the outside.
- Triangles have 3 straight sides and 3 vertices.
- Rectangles have 4 straight sides and 4 vertices.
- Squares are a type of rectangle that have 4 sides the same length.
Keywords
Circle - A 2D shape with one curved line around the outside.
Triangle - A 2D shape with 3 sides and 3 vertices.
Rectangle - A 2D shape with 4 sides and 4 vertices.
Square - A 2D shape with 4 sides the same length and 4 vertices.
Common misconception
Children may think that a square is not a rectangle.
Count the sides and vertices of rectangles (including squares) to show they all have 4 (concept is revisited throughout Year 1 and beyond).
Teacher tip
Look for 2D shapes in the environment, for example rectangles painted on the playground, in pictures on the wall. A true 2D shape cannot be handled as it only has 2 dimensions. We can use the language of 'imagine' so that cut-outs can be explored.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
