## Closed Captioned Video: Algebra Applications: Variables and Equations, 3 |
Closed Captioned Video: Algebra Applications: Variables and Equations, Segment 3: River Ratios
Why do rivers meander instead of traveling in a straight line? In going from point A to point B, why should a river take the circuitous route it does instead of a direct path? |
Applications of Equations and Inequalities, Variables and Unknowns, Variable Expressions | |

## Closed Captioned Video: Geometry Applications: Circles, 2 |
Closed Captioned Video: Geometry Applications: Circles, Segment 2: Circles and Arcs.
The Roman Coliseum is a large elliptical structure. Yet, the Romans likely used circular arcs to build it. This segment explores the properties of circles and shows how arcs can be used to create elliptical shapes. |

## Instructional Resource | Geometric Construction | Constructing an Egg Shape |
Instructional Resource | Geometric Construction | An Egg Shape
In this instructional resource, we show the steps in constructing an egg shape. In the process, students learn about using common points of tangency to create smooth curves from two different shapes. This activity can be done with pencil, compass, ruler, and grid paper. |
