## Decimals and Exponents [electronic resource]

This video describes how whole numbers and decimals are used in the monetary system, how to calculate costs in foreign currencies, and how to use exponents. Dramatized segments and computer animations focus on ways to determine the international value of U.S. dollars at a currency exchange; select chairs for an interior decorating job while staying within a budget; and calculate interstellar distances using scientific notation-and imagination.

## Measurement [electronic resource]

This video describes how to estimate costs of products and services, determine the circumference of an object and its effect on motion, and calculate area and volume. Dramatized segments and computer animations illustrate ways to use measurements taken from blueprints to estimate construction costs; determine tire sizes, which affect vehicle speed; and calculate a running track's circumference to fairly stagger the start lines.

## Coordinates [electronic resource]

This video describes how to identify points, plot ordered pairs on a graph, use map coordinates to find locations, and apply graphical break-even analysis to linear functions. Dramatized segments and computer animations illustrate ways to describe positions on a game board by using coordinates; program an industrial robot to assemble TVs in a factory; use a road map while traveling; and evaluate the impact of franchise costs and product prices on profit at a frozen yogurt bar company.

## Is God a Number? [electronic resource]: Maths That Mimic the Mind

If mathematics underpins the elegant precision of the macroscopic and microscopic worlds, is there a Master Mathematician as well? This fascinating program examines the computational paradigms being used to model human consciousness and to quantify reality, from Euclidean geometry to fractal transform algorithms. Oxford mathematician Sir Roger Penrose, quantum physicist Reverend John Polkinghorne, compression technology expert Michael Barnsley, and physiologist Horace Barlow seek to understand how the brain functions-and grope for evidence of a guiding force. Outstanding computer graphics enhance this exploration of inner and outer space.

## Introduction to Math in Technology [electronic resource]

Introduction to Math in Technology is an eleven-minute video which is part of the series, Math in Technology. "But why do I need math?" Now, using this series, give students a clear, definitive, and logical answer. Math is necessary to get the job done in most technical fields, including auto mechanics, electricity/electronics, and the building trades. Each video shows real-life problem situations solved by using practical math and actual computations on the screen. Use Introduction to Math in Technology as an overview and then progress to specific topics. At last..a program to help your students succeed in the world of technical math.

## Bows, Arrows, and Aircraft Carriers [electronic resource]: Moving Bodies With Constant Mass

In this program, geometry is combined with approximation to solve relatively complex problems involving shooting an arrow and landing an airplane on the deck of an aircraft carrier. Emphasizing the value of sketching as a visualization tool, the program also explains how the solution of the archery problem, through geometric inversion, can help solve the problem of a plane landing.

## Doors, Heart Valves, and Flic-Flacs [electronic resource]: Moments

After explaining the principle of moments, this program shows how apparently dissimilar physical phenomena are actually mathematically similar through the examples of a synthetic heart valve, a lock gate, and the gymnastic maneuver known as a flic-flac, or back handspring. The need to make careful approximations during the modeling process is stressed.

## Bikes and Cars [electronic resource]: Centripetal Acceleration

This program considers the idea that circular motion must imply a force or component of a force toward the center of a circle, as in the Newtonian theory of how the Moon orbits the Earth. The reasons why bicyclists lean during turns, why roads are banked, and why car tires react as they do during a turn are investigated.

## Math in Construction Technology [electronic resource]

In this dramatized program, a contractor trainee prepares an exterior painting estimate for a house that has been vandalized by taking exact measurements, calculating square footage using geometry, adding cost of materials, and multiplying labor costs per hour. Afterward, a group of teens gets ready to build a bike repair shed by reading blueprints, calculating floor area, and squaring the shop's footprint by equalizing the floor's diagonal measurements.

## Parachuting [electronic resource]: Moving Bodies With Constant Mass

This program uses a parachutist to demonstrate the effects of drag on the force of gravity, showing how to make mathematical approximations and how the resultant forces can be equated to the product of mass and acceleration. A first-order differential equation is then used to find the minimum height from which a parachutist can jump without injury.

## Reading a Ruler [electronic resource]: English and Metric Measurements

In the first lesson, the different forms of English measurement are discussed and displayed as they would appear on a ruler. The viewer also learns how to understand fractions when measuring and how to find exact measurements using a ruler. The second lesson deals with the metric system by introducing the meter and other metric measurements. Viewers learn how to read a meter stick, and common abbreviations of metric measurements are discussed. Viewers also learn how to convert measurements using the decimal point.
