By the end of this unit you will be able to:

• Understand when to use Venn diagrams.
• Draw Venn diagrams.
• Interpret Venn diagrams.

Fraction comparison with lowest common denominators.

This video explains how to order fractions by their size.

YouTube video that explains how to use prime factorization to find the highest common factor and lowest common multiple. It is very simple using the method described in the video.

This video looks at set notation, Venn diagrams and probability.

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

This online lesson explains what rotations are.

Sometimes, when the probability problems are complex, it can be helpful to graph the situation. Tree diagrams and Venn diagrams are two tools that can be used to visualize and solve conditional probabilities.

This online lesson explores these two tools.

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.
