The numerator and denominators are increased to larger numbers. They do a number of different examples. Video is good quality and good for all students as review or initial learning of the concept.
Converting Improper Fraction to Mixed Number
Instructor uses a white board to demonstrate how to convert improper fractions to mixed numbers. Students learn that a proper fraction is a fraction whose numerator is less than or equal to its denominator. For example, 3/7, 16/18, and 4/4 are proper fractions. And an improper fraction is a fraction whose numerator is greater than its denominator. For example, 5/2 and 10/3 are improper fractions. Note that an improper fraction can be rewritten as a mixed number. For example, 5/2 can be rew
Absolute Value & The Opposite of a Number
The first thing that is discussed in this video is the definition of absolute value. Absolute value actually represents distance and is always positive, the symbol of an absolute value is the two bars around the value. Distances are always positive that is why absolute values are always positive. They show absolute value using a number line. Many examples are given, when an equation is between the two bars it means the answer should be in absolute value terms. Then they discuss the opposite of a
Learn what absolute values are and how to work them in this short, computer animated video. Key concepts covered are: absolute values, distance from zero, number lines, and writing and reading absolute values. The video ends with a 10 question, fill in the blank quiz.
Direct Proportion Using Hooke's Law
This is a lesson excerpt. To see the whole video go to mindbites.com/lesson/918. This video explains direct proportionality. Professor Burger uses a real-world example of a spring and Hooke's Law using a slinky. Hooke's law states that the distance a spring stretches varies directly to the force applied. If force, f, is directly proportional to distance, d, then d~f or d=kf. This equation allows us to find the constant, k, of how much the spring stretches when force is applied. After
Mean Median and Mode video
Video describing Mean Median and Mode from NextVista for Learning. Instructor is working problems on whiteboard while explaining the procedures.
Converting Between Decimals and Percents
Instructor uses a white board to demonstrate how to write percents as decimals and decimals as percents. For example, to write 82% as a decimal, think of 82% as 82/100, and remember that dividing by 100 moves the decimal point two places to the left, to get 0.82. So 82% can be written as the decimal 0.82. Since a percent can be written as a decimal by moving the decimal point two places to the left, a decimal can be written as a percent by moving the decimal point two places to the right. For ex
Fractions - Rap Song by Mr. Duey
Mr Duey performs a live action rap song about fractions. The song teaches about improper fractions, and how to get a percentage from a fraction with visuals of the mathematical computations during the rap. Entertaining while learning for kids.
Students learn that two fractions are equivalent if the fractions are the same when they are written in lowest terms. For example, 4/7 and 8/14 are equivalent fractions, because they are both equal to 4/7 when written in lowest terms. Students also learn to find fractions that are equivalent to a given fraction by multiplying the numerator and denominator of the given fraction by the same number. For example, to find fractions that are equivalent to 1/8, multiply the numerator and denominator by
Adding Mixed Numbers
Students learn to add mixed numbers by first adding the fractions, then adding the whole numbers. For example, to add 4 2/5 + 7 4/5, first add 2/5 + 4/5 to get 6/5, then add 4 + 7 to get 11. So 4 2/5 + 7 4/5 = 11 6/5. Notice, however, that the answer, 11 6/5, contains an improper fraction, 6/5, which is the same as 1 1/5, so 11 6/5 can be rewritten as 11 + 1 1/5, which simplifies to 12 1/5. So 4 2/5 + 7 4/5 = 12 1/5. Note that some of the problems in this lesson also require the student to find
Adding Fractions with Unlike Denominators
In this video they show how to add fractions with unlike denominators. The LCD or lowest common denominator is found and the fractions are converted. The LCD method is shown to students. Then the fractions are added. At the end of the video there are problems for the students to practice on. Video is good quality and good for all students as a review or initial learning of the topic.
Introduction to Fractions Part 4
In this video they are teaching the lowest common denominator. They start with a fraction problem with all different denominators, so they need to find the lowest common denominator. Some examples are done. Video is good quality and good for all students as review or initial learning of the concept.
How To Learn Multiplication Tables
In this video learn that when learning multiplication tables, fill in as many rows as possible without looking for the answer. A math teacher explains how to make a multiplication, gives tips on how to learn the table, and explains how to check how well a multiplication table has been memorized.
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing or learning place value. This video has humor, which helps make the lesson fun. Video shows how to use the number line, shows how to use the number line where the problem has more than two addends. Then they show how to add in different order by grouping numbers, knowing which numbers add up to 10 to make it easier. This video gives many examples to reinforce the lesson taught. Video is good qualit
Addition on a Number Line
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing or learning addition on a number line. This video shows how to add numbers using a number line, some of the numbers they use start with a negative, then they add a positive number. They show many different examples. They also use the number line to show how to find a missing addend, -10 + x = 2. Video is good quality and good for all students as review or initial learning of the concept.
Subtraction on a Number Line
This video indicates it is for pre-algebra, however this would be good for anyone who is reviewing subtraction. In this video they show how to subtract using the number line, this includes negative numbers. They do this using many different examples. Then they do a word problem using the number line and then equation form. Once again they do a few examples. Video is good quality and good for all students as review or initial learning of the concept.
