## Algebra (Class 84)

**Overview**

In today’s class we continue our work examining the relationship between the length of the side and the area of a rectangle with a fixed perimeter in order to develop equations which can be used to describe and predict different measurements of these rectangles.

**Textbook Sections**

§12-4 (Txt. p.572) Graphs of Quadratic Functions

**Key Attitudes**

Mathematics is about generalizing and applying patterns.

**Key Ideas**

Equations can be written to represent quadratic relationships.

Equation can be used to predict key features of a graph of a parabola.

**Key Skills**

Calculate the area of a rectangle with a fixed perimeter given one dimension.

Graph non-linear data.

Use graphs and equations to make predictions.

Determine the perimeter of a rectangle given a table of values or graph.

Create equations given a graph or a table of values that can be used to predict the area of a rectangle with a fixed perimeter when the length is known.
