Notation and Terminology

Check for the following:

•I did not use calculator notation. (I didn’t include things like ‘x^2’ for or Sn for Sn) •I used appropriate mathematical vocabulary.

Communication

Check for the following:

•The reader will not need to refer to the list of questions in order to understand my work. •My responses are not numbered.

•I have an introduction, conclusion, title page, and table of contents. •All graphs are labeled – Each graph has a title, labeled axes, and appropriate scale. •My graphs and tables are within the body of my work. They are not separate or in an appendix. •I have explained why I made the choices I did when going through the task. •I did not include key stroke sequences, e.g. “I pressed the 2nd key, then TRACE…” •My tables do not straddle pages.

•My tables are labeled well, including my variable definitions in each column.

Use of Technology

Check for the following:

•I used technology to illustrate my points and ideas. I didn’t just “stick in” a graph. •Each graph or table (or other piece of tech.) is accompanied by explanations and my ideas. •I did not include too many graphs on the same axes – my graphs are easy to read.

Mathematical Process (Type 1)

Check for the following:

•I explicitly defined variables and parameters the first time I used them, even if they were already defined in the portfolio handout.

•I stated any constraints/limits on the values of the variables (e.g., “time cannot be negative”). •I did not state conjectures/ideas as facts.

•I used proper mathematical strategies to produce my data. •I organized my data in a table, chart, or other useful representation. •I tested my general statement by using known data.

•After testing my general statement with known data, I considered further examples in order to further test and apply my general statement.
