Charting of basal body temperatures is used in some methods of fertility awareness, such as the sympto-thermal method, and may be used to determine the onset of post-ovulatory infertility. [4] When BBT alone is used to avoid a pregnancy, it is sometimes called the Temperature Rhythm method.
Post-ovulation methods (i.e., abstaining from intercourse from menstruation until after ovulation) have a method failure rate of 1% per year. The symptothermal method has a method failure rate of 2% per year. Cervical mucus–only methods have a method failure rate of 3% per year. Calendar rhythm has a method failure rate of 9% per year.
Two well-known mucus-only methods are the Billings ovulation method and the Creighton Model FertilityCare System. If two or more signs are tracked, the method is referred to as a symptothermal method. Two popular symptothermal systems are taught by the Couple to Couple League and the Fertility Awareness Method (FAM) with Toni Weschler. A study ...
Sometimes, these are only alluded to in the public literature. An example is a book of exercises, described on the back cover: This book contains almost 350 exercises in the basics of ring theory. The problems form the "folklore" of ring theory, and the solutions are given in as much detail as possible. [2]
The Chisanbop system. When a finger is touching the table, it contributes its corresponding number to a total. Chisanbop or chisenbop (from Korean chi (ji) finger + sanpŏp (sanbeop) calculation [1] 지산법/指算法), sometimes called Fingermath, [2] is a finger counting method used to perform basic mathematical operations.

The use of multiple representations supports and requires tasks that involve decision-making and other problem-solving skills. [2] [3] [4] The choice of which representation to use, the task of making representations given other representations, and the understanding of how changes in one representation affect others are examples of such mathematically sophisticated activities.
