Explore the concept of the mean and how variation in data can be described relative to the mean. Concepts include fair and unfair allocations, and how to measure variation about the mean.
In mathematics, symmetry has more than just a visual or geometric quality. Mathematicians comprehend symmetries as motions
Examine your intuitive notions of what makes a "good copy" and then progress toward a more formal definition of similarity. Explore similar triangles and look into some applications of similar triangles, including trigonometry.

Investigate the circumference and area of a circle. Examine what underlies the formulas for these measures, and learn how the features of the irrational number pi (π) affect both of these measures.
Extend your understanding of fractions and decimals. Examine terminating and non-terminating decimals. Explore ways to predict the number of decimal places in a terminating decimal and the period of a non-terminating decimal. Examine which fractions terminate and which repeat as decimals, and why all rational numbers must fall into one of these categories. Explore methods to convert decimals to fractions and vice versa. Use benchmarks and intuitive methods to order fractions.
Dave visits Mount Vernon, Monticello and Montpelier recalling the achievements of the Presidents who lived there and their aims for the estates they called home. He highlights features of Georgian and Palladian architecture and provides insightful anecdotes associated with each home. These anecdotes concern the lives of African slaves and indentured servants, epithets on the graves of the tree Presidents, and stories of Dolley Madison's successes in Washington. Viewers gain an understanding of the private lives of Presidents Washington, Jefferson, and Madison.
Learn about the relationships between units in the metric system and how to represent quantities using different units. Estimate and measure quantities of length, mass, and capacity, and solve measurement problems.
Systems of synchronization occur throughout the animate and inanimate world. The regular beating of the human heart, the swaying and near collapse of the Millennium Bridge, the simultaneous flashing of gangs of fireflies in Southeast Asia: these varied phenomena all share the property of spontaneous synchronization. This unit shows how synchronization can be analyzed, studied, and modeled via the mathematics of differential equations, an outgrowth of calculus, and the application of these ideas toward understanding the workings of the heart.

How do religions interact, adopt new ideas, and adapt to diverse cultures? As the missionaries, pilgrims, and converts of Buddhism, Christianity, and Islam moved around the world, the religions created change and were themselves changed.
From Constantinople, the Byzantine Empire carried on the traditions of Greece and Rome.n
This program on fractions is the fifth of 13 programs within the mathematics section of the series GED Connection. This episode explains the concept and many applications of fractions to make them more understandable and useful to adult learners who may have been previously intimidated by them. It explains a fraction as both a part-to-whole relationship as well as another way to write a division problem, using numerator and denominator. The program shows real-life uses of fractions in accurately measuring something, keeping time to musical beats, and in a horse trainer's calculations of required dosage and supply of medicine needed. The program explains how to find common denominators for adding and subtracting fractions, as well as how to subtract by borrowing from the whole number. Cross canceling or factoring is shown to be an easy way of simplifying a problem. Composites, numbers with many factors, and prime numbers, those whose only factors are one and themselves, are also addressed. Dividing is shown to be the same as multiplying by the reciprocal; and dividing by a number less than one is done the same way, except the result is a higher number than the dividend.
