Rubric for PBA's5 Your solution shows that you have TOTALLY MASTERED the skill or concept involved, meaning that you:
*Have clearly show all the steps of your reasoning*Have demonstrated a full understanding of the concepts involved*Have used notation correctly*Have organized your work NEATLY and LOGICALLY on the page according to the standards expected by mathematicians around the world*Have made NO algebraic errors
4 Your solution shows that you have A GOOD GRASP of the skill or concept involved, meaning that you:
*Have demonstrated a strong understanding of the concepts involved, BUT . . .
you made some minor errorOR . . .
you failed to present your work NEATLY and LOGICALLY on the page according tothe standards expected by mathematicians around the world
3 Your solution shows that you have SOME CONCEPTUAL UNDERSTANDING of the skill or concept involved, but have no thoroughly mastered it, meaning that you made one or more major errors such as: (i) not completely answering the question, (ii) showing confused reasoning, (iii) not using consistent notation, (iv)writing muddled prose, AND/OR (v) making multiple errors in computation

2 Your solution shows that you have A MINIMAL CONCEPTUAL UNDERSTANDING of the skill or concept involved, but are still unsure about the basic aspects of the topic, meaning that you made one or more major errors such as: (i) not completely answering the question, (ii) showing confused reasoning, (iii) not using consistent notation, (iv) writing muddled prose, AND/OR (v) making multiple errors in computation
HOWEVER . . . in spite of these difficulties, you wrote some thoughtful questions or comments that show me you know you need to do more work in this area and are prepared to take active steps to improve your learning
1 Your solution shows that you have A VERY WEAK UNDERSTANDING of the skill or concept involved, meaning you may have used confused reasoning, poor prose, AND/OR made one or more serious errors in computation
0 You left the problem blank

Rational NumbersA Recipe for Success
On May 15, 2005, a group of volunteers met in Las Vegas to create what would become the world's largest cake. In order for the cake to qualify for the Guinness Book of World Records, it had to meet the following qualifications:
contain traditional ingredients in the correct proportions,be prepared in the same manner as a normalsized cake,be prepared according to appropriate hygiene standards, andbe totally edible and safe to eat.
To create the world's largest cake, the organizers had to begin with a recipe for one cake and scale the ingredients accordingly. A sample recipe for one cake is shown below.
