### When and Why Do We Write Quadratic Equations?

In this video lesson, students revisit some situations that can be modeled with quadratic functions. They analyze and interpret given equations, write equations to represent relationships and constraints (MP4), and work to solve these equations. In doing so, students see that sometimes solutions to quadratic equations cannot be easily or precisely found by graphing or reasoning.

### Writing an Expository Paragraph Using Time Order - Ndakinna Wilderness Project

Students will watch a video that shows kids camouflaging themselves in order to blend into nature so they can watch wildlife. The kids follow a sequence of steps in order to camouflage themselves. The students will take notes on this process and write a paragraph that conveys the steps in proper order.

Overview
Students watch a video segment, take notes and using a time-order organizational structure, write a paragraph about how to camouflage themselves.

Why is this an important concept?
When learners can take ideas and sort them by order according to time, they can better comprehend the complexity, sequence, and relationships among the ideas. Noting the relationships among ideas leads to the ability to generalize, categorize, sort, evaluate, and understand new information.
