Introduction to magnetism: Wikipedia article that provides an overview of the concept.

The force that acts across the air gaps between magnets is the same force that creates wonders such as the Aurora Borealis. In fact, magnetic effects pervade our lives in myriad ways, from electric motors to medical imaging and computer memory. In this chapter, we introduce magnets and learn how they work and how magnetic fields and electric currents interact.

This online interactive lesson discusses what reflections are and provides examples of reflections.

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

This online lesson explains what rotations are.

In this lesson you will learn about:

1. Enlargement and reduction of shapes using a scale factor.
2. Reflection of geometric shapes.
3. Translation of geometric shapes.
4. Rotation of geometric shapes.

This online lesson explores the concept of translations.

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.
