Trapezoids

This geometry tutorial discusses the theories of trapezoids. Mansfield ISD teacher Scotty Hale presents.

Fraction to Decimal Lecture

Students learn to convert fractions to decimals. For example, to convert the fraction 7/10 to a decimal, first read the fraction as "7 tenths". Next, since the tenths place is one place to the right of the decimal point, 7 tenths can be written as the decimal 0.7. To convert 11/20 to a decimal, first find a fraction that is equivalent to 11/20 that has a denominator of 100, so multiply both the numerator and denominator by 5, to get 55/100. Next, read the fraction as "55 hundredths", which can b

Equivalent Fractions

Introduction to the concept of equivalent fractions with examples. The instructor uses the Paint Program to illustrate his points.

Division with Fractions

This video indicates it is for pre-algebra, however this video would be good for anyone who is reviewing or learning division of fractions. In the video division of fractions starts with dividing a whole number by a fraction. The instructer uses a number line to show this concept, then does the problem, when doing the problem he uses the reciprocal and then multiplies. He does a few examples using both of these methods. Then they move on to the problem, change division to multiplication, cross c

Addition With Number Line

Uses the number line to show addtion. It is narrated by a jumping bean. It shows the concept clearly and is engaging to watch.

What Is the Meaning of Congruent?

The meaning of the word congruent is very similar to being equal, and it is often used in geometry in reference to side lengths and angle degrees. The instructor uses a document camera to explain this concept.

Introduction to Volume

This animation, from the Pilot Math Essentials 10 series, explains the concept of Volume when the Pilot characters decide to throw a hot tub birthday party for Lian.

How to Find Probability and Chance

This five minute video does a very good job of explaining probability. This is good for most age groups. You need to have a follow-up activity to use, especially in using groups to work on this concept. A good introduction video.

Capacity - Standard Measurement

This is a great basic introduction to the concept of capacity using standard measurement. Students work together to give examples of various ways to measure capacity in this video.

Comparing Integers Using Inequalities

In this video they discuss inequalities. They show the greater than/less than symbol. They then explain these symbols using a number line. On a number line the greater than symbol "" "is greater than "or" is to the right of" on the number line. Then they show the "" symbol which is "less than" or "is to the left of" on the number line. They show a number of examples using these symbols. They proceed to the greater than or equal to symbol and the less than or equal to symbol. Once again they do m

Electric Circuits

This video introduces the concept of an electric circuit. It describes the difference between an open and closed circuit.

Orbitals

Instructor talks briefly about the theories of Bohr and introduces orbitals. Instructor uses his computer screen and different colors to educate students. Instructor says this video series introduces information covered in a first-year high school course in chemistry.

Electrons

Using an animated model of an atom, Eureka! illustrates how electrons whiz so quickly round the nucleus that they appear to form layers. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Molecules in Liquid

As molecules in a solid get hotter, they vibrate faster and faster and eventually slip out of their lattice-work pattern. When this occurs, the substance melts, changing from a solid to a liquid state. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Work

A circus strongman and a clown help present the physics definition of work. Concept: Work = force x distance. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Heat as Energy

Heat is produced whenever there is movement and friction between two objects. Since movement is a form of energy, it follows that heat must also be a form of energy. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Radiation Waves

Viewers learn that one of the chief ways in which heat energy moves is in the form of waves. This kind of heat transfer is called radiation. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Radiation Spectrum

Viewers learn that the waves of heat energy radiated by the sun come in many forms, which together make a band, or spectrum, of energy waves. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level.

Introduction to Motion

Introduction to basic physics of motion. Introduces the concept of variable velocity/acceleration. This video, which is suitable for high school students, starts with a black screen because the instructor uses it as a 'chalkboard.'

Inertia

This program introduces the series and sets forth the concept of inertia, the first law of physics: Things like to keep on doing what they're already doing. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in a simple and well-illustrated way. Good for students of any elementary school level. The 'meat' of the video starts at 01:28.
