Triangle Angle Sum
This video explains that the sum of the three angles in any triangle adds up to 180 degrees. The importance of this fact in Geometry cannot be emphasized enough. The triangle angle sum theorem is used in almost every missing angle problem, in the exterior angle theorem, and in the polygon angle sum formula. (4:06)
Triangle Side and Angle Inequalities
This video explains why triangle side and angle inequalities are important when solving proofs. In any triangle, the largest angle is opposite the largest side (the opposite side of an angle is the side that does not form the angle). The shortest angle is opposite the shortest side. Therefore, the angle measures can be used to list the size order of the sides. The converse is also true: the lengths of the sides can be used to order the relative size of the angles. (1:54)
How to Find the Area of a Trapezoid
Note: The word trapezoid is spelled incorrectly in the video. John, a math teacher in the U.K., demonstrates on a small whiteboard how to find the area of a trapezoid. The instructor does one step at a time. (02:45)
Finding Area of a Parallelogram
Instructor demonstrates how to find the area of a parallelogram using the formula. One example is modeled using a step by step approach to plugging the values for specified variables in to the formula. Video is good quality and good for all students as a review or initial learning of the topic.
Perimeter of a Parallelogram
The instructor uses an electronic sketchpad to demonstrate how to find the perimeter of a parallelogram. One example is modeled using a step by step approach for plugging values in to specified variables in the formula. Video is good quality and good for all students as a review or initial learning of the topic.
The Rhino Song
This simple animation introduces young learners to the rhino. The video talks about its shape, its poor eyesight, and its location.
Domestic Animals
In this video they discuss what domestic animals are and gives some examples of domestic animals. Some domestic animals they show are cats, dogs, horses, cows, and pigs.
Learn About Domestic Animals
This simple animation (with the help of a talking elephant that drives) introduces young learners to animals that live on farms and in homes.
ABC's and Phonics with Puppy Dog
Strong visuals, letter repetition, and a comprehensive review teach children the alphabet. Live action of children singing and dancing while the traditional ABC song is sung. At 4 minutes and 25 seconds, simple objects are introduced for the letter "A." Snippet ends there. Video introduction is nearly 2 minutes long. (5:03)
ABC Phonics Chant With Musical Accompaniment
This video is a phonics chant to help students practice and review their phonics and alphabet at home. Each letter is shown on the screen first in upper and lower case. Then the sound of each letter is made. Finally, the letter name and sound are stated with a picture of an item beginning with the designated letter and sound. For example, M, /m/, mouse. The letters are easy to see and the sounds are clearly made, making this great for phonics practice.
Solving Inequalities in One Variable: Part 1 of 2
The instructor uses an electronic sketchpad to demonstrate how to solve linear inequalities in one variable. This video is part 1 of 2 and several problems are solved and plotted on a number line.
Graphing Linear Inequalities in Two Variables
This video begins with a simple inequality, then explains how to graph the inequality. The instructor begins by showing how to graph the boundary line, then tells how to show the correct solution set on the graph by shading.
Graphing Linear Inequalities from Standard Form
Instructor uses power point to demonstrate how to graph linear inequalities in standard form. Examples model finding the x- and y-intercepts, drawing a line through the two intercepts and forming a boundary line. The instructor then discusses whether the boundary line is dashed or solid and which way to shade the inequality, above or below the boundary line.
Solving and Graphing Linear Inequalities in Two Variables, Part I - Khan Academy
In this video, Sal Khan demonstrates how to solve and graph a linear inequality (y > 5). He starts with a number line. Salman Khan is the recipient of the 2009 Microsoft Tech Award in Education. (02:14) There is a lot of information on the screen--the viewer may want to open the video to 'full screen.' (02:15)
Graphing Systems of Inequalities, Part 2
The instructor in this video, Sal Khan, in an easy, conversational tone, continues to discuss how to graph inequalities. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small.

Melbourne 1956: The Games of the XVI Olympiad The Games of the XVI Olympiad, from Melbourne, Australia. Video gives facts about the water polo game that became known as the “Blood in the Water” match. Video also shows a slide about the boycott. There is no speaking in this video, the Olympic Theme plays in the background. .
Tokyo 1964: The Games of the XVIII Olympiad
The Games of the XVIII Olympiad, from Tokyo, Japan. These were the first Games held in Asia. Video shows pictures of the Olympic flame and gives a little information about the games. There is no speaking in this video, the Olympic Theme plays in the background. (1:38)
Helsinki 1952: The Games of the XV Olympiad
The Games of the XV Olympiad from Helsinki, Finland. These Games were best known as the first appearance from the Soviet Union. PowerPoint type presentation. (1:36)
Seoul 1988: The Games of the XXXIV Olympiad The Games of the XXXIV Olympiad, from Seoul, Korea. This video gives important facts about the Seoul Games, the mascot of the games, Seoul became the second Asian city (after Tokyo) to host the Olympic Games, American Florence Griffith Joyner won three gold and one silver medal in track and field, Ben Johnson of Canada wins the 100 meter, but is later disqualified after a positive test of stanozolol, thus giving the gold to Carl Lewis
