These three short online lessons discuss asteroids, comets and meteors.

Three activities which illustrate the law of exponents.

This is a simple video which describes how indices problems are solved using simplified laws.

Other objects in the solar system are discussed in this online textbook viz. asteroids, meteorites, comets and dwarf planets.

Online problems where the student is required to simplify the expression using the product property of exponents.

An activity explaining the properties of exponents.

This online lesson explains what rotations are.

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

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.
