Rating scale

A The solution shows a deep understanding of the problem including the ability to identify the appropriate mathematical concepts and the information necessary for its solution. Student applies procedures accurately to correctly solve the problem.

B+ The solution shows that the student has a broad understanding of the problem and the major concepts necessary for its solution. Mathematical procedures were used, and correct answer may not have been achieved. Minor Revisions are suggested but not required.

B The solution shows that the student has a good understanding of the problem and the major concepts necessary for its solution. Mathematical procedures were used, but correct answer may not have been achieved. Some Revisions are suggested, but not required

C+ The solution shows that the student has more than a basic understanding of the problem and the major concepts necessary for its solution. Mathematical procedures were used, but correct answer was not achieved. Revisions are required.

C The solution addresses some, but not all of the mathematical components presented in the task. There is some evidence of mathematical reasoning. Student could not completely carry out mathematical procedures. Revisions are required.

F There is no solution, or the solution addresses none of the mathematical components presented in the task. There were so many errors in mathematical procedures that the problem could not be solved Major Revisions are required.

Directions for learner

This assessment involves compiling information about an individual’s food intake over a two day period. Each question below performing calculations on the data you gathered, and summarizing the calculations and verbal descriptions of your results.

PART 1: Complete the following table.

1. List all the food that you, a friend, or a relative consumed over a two day period on the table I below.

(You must list at least 6 items for each day)

2. Conduct an internet search using Google or any other search engine to fill-in the calories, fat, protein, carbohydrate, calcium (Ca), iron (Fe), vitamin A, and vitamin C on the table I below. (If the exact item is not found, use the information from a similar item)

Table I

3. Use the above table I to compute the daily consumption of calories, fat, protein, carbs, calcium (Ca), iron (Fe), and vitamin C for the two day. Fill-in the Day 1, Day 2 and two- Day Total columns on table II.

4. What fractional part of calories, fat, protein, carbs, calcium (Ca), iron (Fe), vitamin A, and vitamin C comes from the food consumed in Day 1. Simplify your answer to the lowest terms, whenever possible on the last column on table II.

Table II

5. What percent of the protein were consumed in Day 1?

6. What percent of the carbohydrates were consumed in Day 2?

7. If the number of grams of fat times 9 equals the total calories from fat, describe how you would determine the total number of calories came from fat over the two days.

8. If the number of grams of protein times 4 equals the total calories from protein, describe how you would determine the total number of calories came from protein over the two days.

9. If the number of grams of carbs times 4 equals the total calories from carbs, describe how you would determine the total number of calories came from carbs over the two days.

10. If the total calories you consume come from protein, fats and carbs, how would you determine the total calories you consumed over the two days?

11. How would you determine the percent of calories you consumed came from carbs?

B. Answer the following questions:

1. Why is it important that your food intake includes calcium (Ca), iron (Fe), vitamin A, vitamin C, and folic acid?
