• Interpret Venn diagrams.

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

This YouTube video explains how river basins are formed.

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

This online lesson explains what rotations are.

This YouTube documentary highlights the ecological and socio-economic importance of the Tana River Basin in Kenya.

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.

Using a Venn Diagram, students identify similarities and differences between two things by listing certain features in a chart containing overlapping circles. Venn Diagrams can be used to summarize, compare, or comprehend information.
