Stanley the Skelton
A seven minute video featuring a talking skelton. A good way to teach students the main bones in the human body. It is best used if there is a handout or other visual to go along with the video. A word wall with the bones listed would also be of value.
The skeletal system serves many purposes in an organism's body, including supporting and protecting body movements and producing red blood cells that the circulatory system carries. Jellyfish and worms have skeletons which are hydrostatic and allow the organism to push water in or out of their bodies. Arthropods have exoskeletons. Humans are vertebrates and have an endoskeleton made mainly of collagen. (06:55)
Operations with Radical Expressions - Yay Math
Adding, subtracting, multiplying, and simplifying radical expressions. White board in a class setting, some interaction, engaging, several examples of increasing complexity. The discussion is clear and understandable. Produced by Robert Ahdoot, yaymath.org
Adding & Subtracting Radical Expressions With Fractions
When adding and subtracting radical expressions, remember that a
radical has a root in it. A math instructor explains how to keep the denominators the same when adding the tops of fractions with examples on a whiteboard. Narrator speech is shown on bottom of screen.
How to Solve Square Root Equations
In math, the square root of one number is found by looking for another number that will equal the first when multiplied by itself. Solve square root equations with tips from a math teacher in this video.
How to Solve Square Root Equations
A lesson on solving square root equations. A math teacher explains to make sure that the square root is definitely by itself, and make sure that the number on the other side is a positive number. Learn how to cancel out a square root with examples being solved on a display. Instructor uses a document camera to presents examples.
Extraneous Solutions to Radical Equations
In this video, the instructor discusses extraneous solutions to radical equations. 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
Introduction to Algebra
This lesson consists of providing you with a Self-Tutorial on what is algebra, what are variables, constants, coefficients, terms, and expressions. The tutor explains the use of proper notation, how to combine like terms, find the negation of an algebraic expression, how to evaluate an expression (by hand and by using your calculator), and finally, there is a VERY detailed section on how to translate English phrases into algebraic expressions.
Finding Missing Numbers in a Number Sentence
This lesson shows a student demonstrating how to find what numbers are missing in simple number sentences. The student uses a number line to explain the first example.
