Examine the operations of addition, subtraction, multiplication, and division and their relationships to whole numbers. Work with area models for multiplication and division. Explore the use of two-color chips to model operations with positive and negative numbers.
Explore the properties of polygons through puzzles and games, then proceed into a more formal classification of polygons. Look at mathematical definitions more formally, and explore how terms can have different but equivalent definitions.
Continue learning about organizing and grouping data in different graphs and tables. Learn how to analyze and interpret variation in data by using stem and leaf plots and histograms. Learn about relative and cumulative frequency.

This program on Ratio, Proportion and Percent is the sixth of 13 programs on mathematics and the 32nd of 39 programs overall in the series, GED Connection. Many guests from various disciplines are featured in roll-ins to explain the basics and how that knowledge is useful in different jobs or settings. Ratios are fractions which can be simplified Ratios are explained by using the unit price of apples and their weight to calculate the total cost. Featured is a city builder who uses floor area ratio to determine the size of a building compared to the size of the lot. Percentages, or parts per 100, are explained in the context of calculating car payments and how much of those payments is principal and much is interest. The importance of Compound interest, or interest on already earned interest is highlighted. Also shown is how to calculate a magazine's price using a percentage discount. Proportional ratios are used to solve missing variable by multiplying cross-products. A cartoonist and a filmmaker demonstrate how they use proportions in their crafts.
