Lesson notes

Indicator: B8.3.3.1.1 - Understand rotation and identify real-life situations involving rotation.

By the end of the lesson, learners can:

Define rotation as a transformation that turns a shape around a fixed point called the centre of rotation.
Identify and describe real-life situations involving rotation from their surroundings.
Distinguish between clockwise and anti-clockwise rotational movement.
Demonstrate a rotation by physically turning an object or shape through a given angle.
Recognise that rotation preserves the size and shape of the object (the image is congruent to the original), without yet drawing images on a coordinate plane.
