To identify and recognise angles
In this lesson, we will start to understand what the word 'angle' means. We will begin to identify angles within objects and shapes before we start to compare the size of angles.

To identify angles inside 2D shapes
In this lesson, we will review what an angle is. We will begin to explore various angles that are found inside 2D shapes and identify patterns between the number of sides and the number of angles.
To recognise right angles
In this lesson, we will build on our knowledge of angles and focus specifically on right angles. We will explore these on their own, in shapes and in everyday objects.
To recognise obtuse and acute angles
In this lesson, we will build on our angle knowledge by introducing the terms 'acute' and 'obtuse' for those angles which are smaller (acute) and greater (obtuse) than right angles. We will have time to look at these angles separately and within different shapes.
To revise angles
In this lesson, we will revisit our knowledge of angles. We will revise what is meant by right, acute and obtuse angles. We will then have an opportunity to identify these angles and draw them.
To identify perpendicular lines
In this lesson, we will build on our knowledge of angles, in particular right angles, and learn to identify perpendicular lines. We will look at these individually and within 2D shapes, as well as having a chance to find these ourselves.
To draw perpendicular lines
In this lesson, we will look in detail at horizontal and vertical lines and how these relate to perpendicular pairs of lines. We will then identify where we find these in the real world and begin to draw them.
To identify and explain parallel lines
In this lesson, we will build on our knowledge of lines and angles to identify pairs of parallel lines. We will identify these individually and within 2D shapes, as well as looking in detail at their meaning.
To revise parallel and perpendicular lines
In this lesson, we will revisit pairs of parallel and perpendicular lines. We will look at how they differ and what they have in common, as well as where they occur in 2D shapes.
To identify rectangles including squares
In this lesson, we will look in detail at the properties of rectangles and learn to identify these propoerties. This will build on our work on angles, particularly right angles.
To describe 2-D shapes based on their properties
In this lesson, we will recap what the various properties of 2D shapes are and begin to identify them within 2D shapes. We will think about how to work efficiently and systematically.
To draw 2-D shapes based on their properties
In this lesson, we will apply 2D shape vocabulary to accurately describe and draw them 2D shapes.
To describe the properties of 3D shapes
In this lesson, we will look in detail at the properties of 3D shapes and learn to identify these properties. This will build on our work on angles and 2D shapes.
To Identify and Describe Lines of Symmetry in 2-D Shapes
In this lesson, we will look in detail at the definition of symmetry and how to recognise this in familiar 2D shapes. This will build on our work on the properties of 2D shapes.
To revise shapes
In this lesson, we will revise our knowledge of 2D and 3D shapes. This will include describing 2D and 3D shapes, lines of symmetry and the new vocabulary we have encountered in relation to these areas.
