Subtracting Decimals with No Place Holder
In this is an easy-to-understand, brief video the instructor uses a sketchpad program to demonstrate how to subtract decimal numbers. Several examples are modeled with emphasis placed on regrouping and lining up the decimals.
This is a brief (approximately) two-minute video from Sal Khan about subtracting decimals using the problem: 9.005-3.6.
Mr. Khan uses computer software for demonstration. The screen is a little 'busy' so the viewer may want to open the screen to 'full screen' to see all more clearly.
Subtracting Decimals - Word Problem
This video is from Sal Khan about subtracting decimals using the problem: Leo has $4,522.08 in his bank account. He deposits another $875.50 and then withdraws $300.00 in cash. How much is left in his bank account?

Mr. Duey - Fractions Rap
This is an excellent, catchy rap by Mr. Duey with lots of examples and great visual effects teaching how to convert fractions to percentages and how to change improper fractions to mixed numbers. (02:35)
This is a lesson on how to divide fractions.The instructor uses a white board. He uses a great expression called 'flip and dip." (03:02)
Basic Math: Lesson 6 - Video Clip #9 - Arithmetic of Fractions: Addition
Concepts covered: Addition of Improper and Proper Fractions and also Mixed Numbers.
Redefining the Wall: Architecture, Materials and Macroelectronics
As a principle element of architecture, technology has allowed for the wall to become an increasingly dynamic component of the built environment. The traditional connotations and objectives related to the wall are being redefined: static becomes fluid, opaque becomes transparent, barrier becomes filter and boundary becomes borderless. Combining smart materials, intelligent systems, engineering, and art can create a component that does not just support and define but significantly enhances the ar

The desert biome is characterized by low precipitation, a high rate of evaporation (seven to fifty times as much as precipitation), and a wide daily range in temperature. The dramatic temperature fluctuations are the result of low humidity, which allows up to 90 percent of solar radiation to penetrate the atmosphere and heat the ground during the day, then for this accumulated heat to be released back into the atmosphere at night. Precipitation in deserts, unlike other biomes, is highly irregula
22.611J Introduction to Plasma Physics I (MIT)
In this course, students will learn about plasmas, the fourth state of matter. The plasma state dominates the visible universe, and is of increasing economic importance. Plasmas behave in lots of interesting and sometimes unexpected ways. The course is intended only as a first plasma physics course, but includes critical concepts needed for a foundation for further study. A solid undergraduate background in classical physics, electromagnetic theory including Maxwell's equations, and mathema
7.1 Evidence required This Part is about showing you can develop a strategy for using and improving your number skills, monitor your progress, and evaluate your overall performance and strategy. The evidence you present must show what you have done as you worked through the processes of planning strategically, monitoring, evaluating and presenting your work.

Of Mice and Children: Unraveling the Effects of a Technologized Infancy
Dimitri's passion is developing actionable strategies to optimize the cognitive, emotional, and social development of preschool children. The pursuit of that passion has taken him from the exam room, to the community and most recently to cages of newborn mice. Christakis' laboratory focuses on the effects of early environmental influences on child health and development. He speaks frequently to international audiences of pediatricians, parents, and educators about the impact of early learning

Three essays on bank efficiency
Since commercial banks play important roles in the financial markets, it is important to evaluate whether banks operate efficiently. Moreover, given increased competition from non-bank financial institutions, commercial banks should operate more efficiently than they did previously. Commercial banks might operate more efficiently if they have superior information. If this is true, bank size should not matter to the operation of the bank. Thus, as long as the bank has superior information, it wil
This video gives a brief description of a Stem-and-leaf plot, how to make them and use them to find the median and range. (08:07)
Relative Frequency Histogram
In this video, an unfinished histogram is pictured. The instructor explains how to complete the histogram and does each step necessary to do so.
Drawing a Histogram
This lesson takes provided data about mass to create a histogram about the data. While the lesson relates to a previous experiment, it still provides good step by step instruction on how to draw a histogram. Graph paper will be needed to follow along and complete the lesson along with the instructor. It is hard at times to see what the instructor is writing because the writing is very small.
In this video (06:08), Mr. Khan explains how to visualize data using a histogram. Mr. Khan uses the computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.
