Mathematical Reasoning

EXPERT

Demonstrates a clear and complete understanding of the nature of the problem. Constructs a correct algebraic or linear equation that can be used to find the number of guests for six tables and the number or tables needed to seat 24 guests.
3: PRACTIONER

Demonstrates a good understanding of the nature of the problem. Constructs and algebraic / linear equation or explanation that can be used to find the number of guests to be seated at six tables or the number of tables needed to seat 24 guests.
APPRENTICE

Demonstrates an understanding of the relationship between the guests and number of tables. Some errors in calculations were observed.
NOVICE

Demonstrates a poor understanding of the relationship between the guests and number of tables. Some errors in calculations were observed.
Mathematical Content

EXPERT

Demonstrates understanding and correct use of an algebraic or linear equation to find the number of guests and tables for the Thanksgiving Dinner.
3: PRACTIONER

Demonstrates understanding and correct use of an algebraic or linear equation to find either the number of guests that can sit at six tables or the number of tables needed to seat 24 guests.
APPRENTICE

Demonstrates limited understanding of use of algebraic or linear equation to find either the number of guests that can sit at six tables or the number of tables needed to seat 24 guests.
NOVICE

Demonstrates limited understanding of use of algebraic or linear equation to find neither amount of guests for six tables nor the amount of tables needed to seat 24 guests.
Multiple Representations

EXPERT

The work is presented in multiple ways including: sketches, tables, written explanations, and equations. There are strong connections between the representations.
3: PRACTIONER

The work is presented in multiple ways including: sketches, tables, written explanations, and equations. The connections between the representations are adequate.
APPRENTICE

The work is represented in multiple ways including: sketches, tables, written explanations, and equations. The connections between the representations are weak and show very little significance to the task.
NOVICE

The work is represented in multiple ways including: sketches, tables, written explanations, and equations. The connections between the representations are not made.
Written Explanation

EXPERT

Explanation is detailed and clear. It shows a clear relationship between the mathematics and the model.
3: PRACTIONER

Explanation is clear and shows a relationship between the mathematics and model.
APPRENTICE

Explanation is somewhat difficult to understand, but includes critical components.
NOVICE

Explanation is difficult to understand and is missing several components or was not included.
Solution

EXPERT

The solution clearly defines a reasonable solution of how many guests could be seated at six tables and how many tables would be needed to seat twenty-four guests.
3: PRACTIONER

The solution clearly defines a reasonable solution of how many guests could be seated at six tables.
APPRENTICE

The solution partially defines a reasonable solution of how many guest could be seated at six tables.
NOVICE

The solution is not clearly defined of how many guests would be able to seat at six tables.
Presentation

EXPERT

The work is presented in a neat, clear, and organized fashion that is easy to read and eye-catching.
3: PRACTIONER

The work is presented in a neat and organized fashion that is easy to read.
APPRENTICE

The work is presented in a fairly organized way but it difficult to read or understand at times.
NOVICE

The work appears sloppy and unorganized. It is difficult to know what information goes together.
