The Alphabet Song
This is a great song to help teach the sounds that each letter makes plus help students learn over 50 new words that go with all the sounds of the alphabet.
"Hip Hop Alphabet" song
"Hip Hop Alphabet" sings about the alphabet in a different, fun way. Some of the lyrics include--"Get ready, get set, hop to the alphabet". The letters of the alphabet are displayed on screen while the singer says each one. The song is repeated several times. This would be a good teaching resource for young students. (1:36)
Comparing Adverbs
This lesson explains the three levels of adverbs: positive, comparative, and superlative. The lesson provides examples of each level. The video is an excerpt and doesn't go into a great deal of detail.
The History of Valentine's Day
This professional video explores the history and legends surrounding Valentine's Day. The presenter explains the legend of St. Valentine. The end of the video consists of impromptu interviews of customers at a greeting card store. (03:59)
Basic Math: Lesson 2 - Equalities & Inequalities
This lesson consists of providing you with a Self-Tutorial on the basics of equalities and inequalities. I go over how to write results in interval notation, inequality notation, and set (set-builder) notation. I also explain in the printed notes how to use your graphing calculator to help you make comparisons between numbers.
Solving Inequalities
This video involves solving linear inequalities. This video starts off with a black screen because the narrator uses it as a 'chalkboard' by using the Paint Program.
Solving Compound Inequalities
This lesson demonstrates how to solve a compound inequality then shows how to graph the inequality. The instructor goes through how to do this step by step on a white board. Then, he shows the solution set on a number line.Â
Solving a Compound Inequality
This video shows how to combine two inequalities. The example used is very simple and the instructor shows the steps necessary to combine the inequalities. He emphasizes the concepts that will be needed to solve more complex compound inequalities in the future.
Linear Inequalities - A Visual Proof
An instructor shows why we flip the sign when multiplying or dividing by a negative when solving inequalities. Â He uses a flip chart and shows several examples including both inequalities and word problems.
Linear Inequalities
If we want to solve for or describe a region in a coordinate plane, we can use linear inequalities. Linear inequalities give us a set of solutions as opposed to just one solution. This video clip explains how to solve linear inequalities using similar methods as in solving multi-step equations, except that there are extra rules when using multiplication and division. We graph linear inequalities by shading regions of number lines or coordinate planes. (6:20)
Solving Inequalities Using Multiplication
This video explains how inequalities follow different rules than equations when dealing with multiplication. Solving inequalities using multiplication involves watching for negative numbers. When we multiply both sides by a negative number we must change the direction of the inequality sign. This happens when using multiplicative inverses to simplify the way we would when solving multi-step equations. (2:11)
Solving Quadratic Inequalities
This video shows the basic procedure and one full example of how to solve quadratic inequalities. The instructor goes through and explains each step as it is written on the white board.Â
Quadratic Formula Song
Learn the quadratic formula and how to use it in problems. This catchy video comes from the Algebra Upgrade online course at www.learningupgrade.com. It is one of those tunes that could get stuck in your head (which could be a good thing when you are trying to remember a formula!).
Quadratic Regression
This instructor in this video, Sal Khan, uses a calculator to perform a quadratic regression. Mr. Khan uses computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The viewer may want to open the video to 'full screen' as the instructor fits a lot of information on a dark screen.
Solving Inequalities in One Variable
This video shows examples of inequalities with one variable and the instructor goes through the steps necessary to solve the inequalities. While he does this, he explains some of the important rules necessary for correctly solving inequalities. He also identifies some common mistakes students make when solving inequalities.Â
Graphing Inequalities on a Number Line
Instructor uses a white board to demonstrate solving inequalities in one variable and graphing the solution on a number line. Â Examples include one-step, two-step, and multi-step linear inequalities. Â
How to Divide Inequalities
How to Divide Inequalities. Part of the series: Math Fractions and Equations. When dividing inequalities, treat the equation like any other standard equation. Flip the inequality sign when dividing an inequality by a negative number with help from a math author and teacher.
Solving and Graphing Inequalities
Inequalities are useful for finding a range of solutions. Solving and graphing inequalities is a key to finding and showing that range. This video clip explains how to solve inequalities using a lot of the same methods as those in solving multi-step equations when dealing with additive inverses, although some things are different when solving inequalities using multiplication. We graph inequalities using number lines. (1:32)
Graphing Inequalities in Two Variables
This is a video tutorial of how to graph and shade inequalities involving two variables. Instead of using a number line, the inequality is graphed on an x,y graph. The instructor relates what is know about graphing equalities and applies this knowledge to graphing inequalities. He works quickly through examples and doesn't show all of the steps needed in drawing the lines on the graph.
Graphing Systems of Linear Inequalities
In this video, the instructor goes through the steps needed to graph a system of linear inequalities. He discusses slope, shows how to draw the line on the coordinate plane, and explains what section of the graph should be shaded. There is some shadow on the white board which makes it a little more difficult to see at times during the instruction.
