This online lesson explains what rotations are.

This video will look at rotation. Rotation involves turning a shape around a set point.

Part 1: Subtracting integers
Part 2: Examples of subtracting integers
Part 3: Common mistakes made when subtracting integers

Students learn about two-axis rotations, and specifically how to rotate objects both physically and mentally about two axes. A two-axis rotation is a rotation of an object about a combination of x, y or z-axes, as opposed to a single-axis rotation, which is about a single x, y or z-axis. Students practice drawing two-axis rotations through an exercise using simple cube blocks to create shapes, and then drawing on triangle-dot paper the shapes from various x-, y- and z-axis rotation perspectives.
