We have been learning about slope in class. The Slope Intercept form of an equation is very important for helping us graph and understand linear situations.
Remember from your foldable from notes section 6-2 that in slope intercept form each variable stands for a different property of the line.
y = mx + b
y value= slope(x-value) + y-intercept
What is Slope?
By definition slope is the steepness of a line. In the web-course you will see many different examples of where you might find slope in the real world. As you work through completing this course you will be graded on the different activities. Complete the tasks in order for homework each night this week as we study Slope in depth in class. You will have Thursday-Monday to complete the final project. All final projects due by Monday in class. Be prepared to present your project to the class!

Learning Objectives for this page:
CCSS.Math.Content.8.EE.B.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
CCSS.Math.Content.8.EE.B.6 Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
Task 1-
Practice identifying slope intercept -Cockroach game!
Play Algebra and the Cockroaches to practice finding slope and y-intercept by placing your cursor over the website below then follow the link that appears below. When you are finished playing answer the questions below and be prepared to share your answers in class tomorrow.

1. What was difficult about this game?
2. Did you find your skills improving the longer you played?
3. What was your highest score?
4. What would make this game even better?
5. Can you think of an internet game idea that would help students understand slope better?
(10 points)

Task 2The pictures to the left are all examples of positive slope.
Find 3 pictures that show negative slope. Copy and paste into a word document and turn in for homework tomorrow (5 pts- completion) Task 3
Remember slope is much more than a hill or a wheelchair ramp. Anytime you are comparing the change in two variables you can determine a slope (temperature and time, money and hours worked, growth over time, etc.) (5pts for completion).
1. Make a list of 3-5 different situations where slope might be found in the real world. Be prepared to share these in class tomorrow. 2. Slope and Pizza? Any ideas how slope could be a factor in choosing toppings on a pizza? (10 points-completion) |
Task 4- Virtual Field Trip- Mt. Everest
![]() FACT: Did you know? Mount Everest was named after Sir George Everest, the surveyor who used mathematical equations to calculate the location and height of the world’s tallest mountain.
|
Step One: Watch the YouTube video on the left to review how to calculate slope.
Step Two: Take the virtual field trip to Mt. Everest by clicking the link below. Be sure to watch the video at the bottom of the page! http://www.airpano.com/360Degree-VirtualTour.php?3D=Everest-Nepal Step Three: Open the document below and answer the questions. Please turn this in for homework tomorrow. (20 points- successful completion of the worksheet and discussion participation in class tomorrow)

Task 5- Final Project
You will create your own real life slope scenario!
We have shared many ideas and examples of linear situations in class this week. It's your turn to come up with one example of a linear situation that has meaning in your life. It could involve a job, sports team, building your favorite pizza, or a hobby that is important to you.
You will present this problem for your classmates using prezi, powerpoint, video or any other form of media approved by Mrs. Obenschain.
Your slides should include:
Initial word problem you have created
Verbal model of the linear situation
Slope intercept representation of your equation
A graph of your equation
The solution to your problem
A verbal explanation of your answer given the situation
This project is worth 45 points. Refer to the rubric below for grading details.
Please submit your presentation by December 13th. We will present in class the week of Dec 16-20.
