Math SL Portfolio – Tips and Reminders Checklist
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.

Internal Assessment – LASCAP’S Fraction
The goal of this task is to consider a set of fractions which are presented in a symmetrical, recurring sequence, and to find a general statement for the pattern.
The presented pattern is:
Row 1
1 1
Row 2...

Circles
Introduction
The objective of this task is to explore the relationship between the positions of points within circles that intersect.
The first figure illustrates circle C1 with radius r, centre O, and any point P. r is the distance between the centre O and any point (such as A) of circle C1.
Figure 1...
...Evaluate/Compare and Contrast/Discuss/Examine models or theories of one cognitive process with reference to research studies (22)
Human beings actively process information and it is cognitive processes that guide behavior. These cognitive processes are influenced by social and cultural factors. One of the cognitive processes is memory. Many researchers and psychologies have proved that the mind can be studies scientifically by developing theories and using a number of scientific research...

As shown from the table above, showing the height achieved by the gold medalists at various Olympic games, the Olympic...
...In Lacsap’s Fractions, En(r) refers to the (r+1)th term in the nth row. The numerator and denominator are found separately, therefore to find the general statement, two different equations, one for the numerator and one for the denominator, must be found. Let M=numerator and let D=denominator so that En(r) = M/D.
To find the numerator for any number of Lacsap’s Fractions, an equation must be made that uses the row number to find the numerator. Because the numerator changes depending on the...
...SL TYPE 1LACSAP’S FRACTIONS
* INTRODUCTION
This investigation is going to do research patterns relates to the Lacsap’s Fractions. For its external structure, Lacsap’s Fraction is analogous to Pascal’s Triangle. Lacsap’s Fraction presents the way of generating and organizing the binomial coefficients. Within this investigation, the work is planning to be divided into two parts. In the first part, the content will relate to the pattern of numerators. In the second part, I...

Lacsap’s Fractions
Lacsap is Pascal spelled backward. Therefore, Pascal’s Triangle can be used practically especially with this diagram.
(Diagram 1)
This diagram is of Pascal’s Triangle and shows the relationship of the row number, n, and the diagonal columns, r. This is evident in Lacsap’s Fractions as well, and can be used to help understand some of the following...

April 11th/2012
In this portfolio, there will be investigations on the topic of the relationship between females of different ages and their body mass index (BMIa measure of one's body fat). Body mess index is calculated by taking one's weight (kg) and dividing by the square of one's height....
