Introduction
Slope is an important piece to designing any building or car you see. Today you and your friends want to climb a ladder to get to your tree house. You want to make a ladder on a slant and high enough to reach the tree house. You will learn about an equation that defines slope. Let's get started!
Task
You will work in groups using websites and YouTube that will be given
use web
Process
Lets first understand the different parts of a line. Below are the different terms, use the resources to find their definition and use to understand y=mx+b
What is the gradient?
What does m stand for?
What does b stand for?
How do you solve for m?

If your treehouse is 10 feet high, what slope could you have? How far away is the bottom of the ladder from the treehouse? Do not make this ladder completely vertical.
Hint: b will equal 0
Evaluation
Group turns in one sheet of paper with their answers.
100 - correct definitions from using the resources on one sheet a paper and a slope
90 - individual papers with correct definitions and a slope
80 - mostly correct answers with individual papers
70 - partial work completed
evaluate each process
Conclusion
Now that you understand making a slope, besides ladders and roller coasters, what else has a close? How can you measure it?
