DOG DEBATE PORTFOLIO
please help me i am very confused and its stressing me out :/
UNIT NAME: EQUATIONS AND INEQUALITIES
Directions: The traditional method for calculating a dog's age in dog years is to
multiply its age in human years by 7. The chart below describes a different method
some veterinarians use to estimate a dog's age based on its size.
Size Small Medium Large Giant
Weight 20 pounds
or less
21‒50
pounds
51‒90
pounds
more than 90
pounds
Age at 2 in
Human Years
23 dog years 24 dog years 22 dog years 20 dog years
Age Increase
Each Year
After 2 in
Human Years
4 dog years 5 dog years 6 dog years 7 dog years
1. Choose a dog breed in each size category. You can use the dog breed charts
on the following page or do research to choose a different breed.
2. Complete a table to show the dog year equivalent for each breed from 2–5
human years.
3. Let x equal the age, in human years, for a dog that is 2 years old or older.
For each of your chosen breeds, write an expression to model its age in dog
years. [Hint: Use (x 2) in each expression.]
4. Choose what you consider to be a really old, but realistic, age for people.
5. For each expression you write, plug in the value you chose in step 4—an old age for a
human—for x. Set each expression equal to A.
6. Solve each equation, and explain what the solution means. Add the old-age
values to your table.
7. Use your solutions to develop a convincing argument for why the method
described in the chart is better than the traditional method.
8. You may wish to do research to find the average lifespan for each dog breed
and use those facts in your argument.
Use your table, equations, solutions, and arguments to create your debate
presentation. Your presentation can be written, but you could also use slide
presentation software or create a video of yourself giving the presentation. Your
completed presentation will be submitted as your portfolio assessment.
It seems like you need help with a dog debate portfolio for your math unit on equations and inequalities. I can assist you with the steps outlined in your assignment.
1. Choose a dog breed in each size category: You can use the provided dog breed charts or do research to choose different breeds. Make sure you select one breed for each size category (Small, Medium, Large, Giant).
2. Complete a table: Create a table where you can list the dog year equivalent for each breed from 2-5 human years. For each breed, calculate the dog's age using the chart's method. For example, for a Small dog, the dog year equivalent at 2 human years is 23.
3. Write expressions: Let x represent the age, in human years, for a dog that is 2 years old or older. Write an expression for each chosen breed to model its age in dog years. Use (x-2) in each expression as a hint. For example, for a Small dog, the expression could be 23 + 4(x-2), where 4 represents the age increase each year after 2 in human years.
4. Choose an old age for humans: Select what you consider to be a really old, but realistic, age for people. This age will be used to compare with the dog ages in the following steps.
5. Plug in the value: For each expression you wrote in step 3, plug in the value you chose in step 4 (old age for a human) for x. Set each expression equal to A, where A represents the age in dog years.
6. Solve the equations: Solve each equation from step 5 to find the value of A, which represents the age in dog years for each breed at the old age you selected. Explain what the solution means.
7. Develop a convincing argument: Use the solutions you found in step 6 along with research on the average lifespan for each dog breed to develop a convincing argument for why the method described in the chart is better than the traditional method of calculating a dog's age in dog years.
8. Create your debate presentation: Use your table, equations, solutions, and arguments to create your debate presentation. You can choose to write it, use slide presentation software, or create a video. Make sure to include all the required components mentioned in the directions.
