Describing a rotation's direction and size
Lesson details
Learning outcome
I can understand the size and direction of rotation.
Key learning points
- Rotations can be either clockwise or anti-clockwise.
- The size of the rotation is given in degrees.
Keywords
Clockwise - Clockwise is the direction that the hands of an analogue clock travel.
Anti-clockwise - Anti-clockwise is the opposite direction to which the hands of an analogue clock travel.
Degrees - The most common unit of measurement for angle. One whole turn is equal to 360 degrees, written 360°.
Common misconception
"Right means clockwise" and "left means anti-clockwise"
This is only true when referencing the top of the object being rotated. Rotating "left" and "right" is incorrect for all other vertices.
Teacher tip
In the Cycle 2 , it is important to note that there are infinitely many answers (you can continue rotating the object through full turns) - this is why it states each rotation is under 360° (or one full turn).

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.
