Recognise right angles
In this lesson, we will learn how to make a right angle measurer (90), then use this to identify right angles within angles, shapes and daily objects.
Recognise acute and obtuse angles
In this lesson, we will learn to recognise acute and obtuse angles and shapes, then draw them on paper.
Angles within a shape
In this lesson, we will learn how to recognise and draw angles within shapes, then understand statements about angles and properties of shapes.
Compare and order acute, obtuse and reflex angles
In this lesson, we will learn about reflex angles, and then consider how to compare and order acute, obtuse and reflex angles.
Reading angles on a protractor (Part 1)
In this lesson, we will learn how to read a protractor and measure accurately to 10°, 5° and 1°.
Reading angles on a protractor (Part 2)
In this lesson, we will learn how to use a protractor to measure multiple angles and angles in a shape.
Reading angles on a protractor Part 3
In this lesson, we will learn how to use a protractor to calculate and measure a reflex angle and an angle in a shape.
Draw angles with a protractor 1
In this lesson, we will learn how to use a protractor to draw acute and obtuse angles as well as identify common mistakes.
Draw angles with a protractor (Part 2)
In this lesson, we will learn how to use a protractor to draw reflex angles and angles within a shape.
Calculating angles on a line or around a point
In this lesson, we will learn how to calculate angles on a straight line, vertically opposite angles and angles around a point.
Calculating angles within a shape 1
In this lesson, we will learn about different types of triangle and how to calculate angles within a triangle.
Calculating angles within a shape (Part 2)
In this lesson, we will learn about different types of quadrilaterals and how to calculate angles within composite shapes.
Calculating angles within a shape 3
In this lesson, we will learn about parallel lines, their angles and how we can use this information within composite shapes.
