Using Games in Education
Games provide an excellent environment to explore ideas of computational thinking. The fact that many games are available both in a non-computerized form and in a computerized form helps to create this excellent learning environment. A modern education prepares students to be productive and responsible adult citizens in a world in which mind/brain and computer working
together is a common approach to solving problems and accomplishing tasks.

Puzzles
A puzzle is a type of game. To better under the purpose, think about some popular puzzles such as crossword puzzles, jigsaw puzzles, and logic puzzles (often called brain teasers). In every case, the puzzle-solver’s goal is to solve a particular mentally challenging problem or accomplish a particular mentally challenging task.

Many people are hooked on certain types of puzzles. For example, some people routinely start the day by spending time on the crossword puzzle in their morning newspaper. In some sense, they have a type of addiction to crossword puzzles. The fun is in meeting the challenge of the puzzle—making some or a lot of progress in completing the puzzle.

Crossword puzzles draw upon one’s general knowledge, recall of words defined or suggested by short definitions or pieces of information, and spelling ability. Through study and practice, a person learns some useful strategies and can make considerable gains in crossword puzzlesolving expertise. Doing a crossword puzzle is like doing a certain type of brain exercise. In recent years, research has provided evidence that such brain exercises help stave of the dementia and Alzheimer’s disease that are so common in old people.

From an educational point of view, it is clear that solving crossword puzzles helps to maintain and improve one’s vocabulary, spelling skills, and knowledge of many miscellaneous tidbits of information. Solving crossword puzzles tends to contribute to one’s self esteem. For many people, their expertise in solving crossword puzzles plays a role in their social interaction with other people.

Why 09/09/09 Is So Special?

Numerologists aren't the only ones excited about Wednesday's date.

Not only does the date look good in marketing promotions, but it also represents the last set of repeating, single-digit dates that we'll see for almost a century (until January 1, 2101), or a millennium (mark your calendars for January 1, 3001), depending on how you want to count it.
Though technically there's nothing special about the symmetrical date, some concerned with the history and meaning of numbers ascribe powerful significance to 09/09/09. For cultures in which the number nine is lucky, Sept. 9 is anticipated - while others might see the date as an ominous warning.

Math magic

Modern numerologists - who operate outside the realm of real science - believe that mystical significance or vibrations can be assigned to each numeral one through nine, and different combinations of the digits produce tangible results in life depending on their application.
As the final numeral, the number nine holds special rank. It is associated with forgiveness, compassion and success on the positive side as well as arrogance and self-righteousness on the negative, according to numerologists.

Though usually discredited as bogus, numerologists do have a famous predecessor to look to. Pythagoras, the Greek mathematician and father of the famous theorem, is also credited with popularizing numerology in ancient times.

"Pythagoras most of all seems to have honored and advanced the study concerned with numbers, having taken it away from the use of merchants and likening all things to numbers," wrote Aristoxenus, an ancient Greek historian, in the 4th century B.C.As part of his obsession with numbers both mathematically and divine, and like many mathematicians before and since, Pythagoras noted that nine in particular had many unique properties. Any grade-schooler could tell you, for example, that the sum of the two-digits resulting from nine multiplied by any other single-digit number will equal nine. So 9x3=27, and 2+7=9.

Multiply nine by any two, three or four-digit number and the sums of those will also break down to nine. For example: 9x62 = 558; 5+5+8=18; 1+8=9.
Sept. 9 also happens to be the 252nd day of the year (2 + 5 +2)...

Loving 9

Both China and Japan have strong feelings about the number nine. Those feelings just happen to be on opposite ends of the spectrum. The Chinese pulled out all the stops to celebrate their lucky number eight during last year's Summer Olympics, ringing the games in at 8 p.m. on 08/08/08. What many might not realize is that nine comes in second on their list of auspicious digits and is associated with long life, due to how similar its pronunciation is to the local word for long-lasting (eight sounds like wealth).

Historically, ancient Chinese emperors associated themselves closely with the number nine, which appeared prominently in architecture and royal dress, often in the form of nine fearsome dragons. The imperial dynasties were so convinced of the power of the number nine that the palace complex at Beijing's Forbidden City is rumored to have been built with 9,999 rooms.

Japanese emperors would have never worn a robe with nine dragons, however.
In Japanese, the word for nine is a homophone for the word for suffering, so the number is considered highly unlucky - second only to four, which sounds like death.

Many Japanese will go so far as to avoid room numbers including nine at hotels or hospitals, if the building planners haven't already eliminated them altogether.

Effective Study Skills
Students often fail to secure good grades despite studying for hours. This is because they have never studied effectively. Unless you know how to make your study hours effective, you cannot get the expected results. Here we will give you some glimpses of effective study skills.

• A study is called effective if you can remember and recall the major segments of the syllabus that you have read. Do not try to cram chapters that you fail to understand. You will never be able to remember them. The easiest thing to do is to seek the assistance of your classmates or the teachers to understand the confusing portions.
• 
  You have to decide what is most important to you. Make your schedule to address those important needs. You should never compromise with your priorities. Never try to finish too many things at a time. Study all the subjects on a regular basis while allotting some time for revisions. Keep yourself motivated. It is better to know the theme of the chapter that you are planning to study. Reading it line by line will then help you understand it better.
• 
  Effective study skills also stress on reading methods. You will see that there are some words that have fonts in bold or italics; you should pay special attention to these. You can also try to find whether the current text refers to any other works of the author that you have read earlier.
• 
  Effective study skills include listening to the explanations given by teachers. You should read and understand the notes that you have taken in the classroom. Following these aforesaid effective study skills will save you disappointments and help you get the desired results.
  
  

Solid Geometry

Solid geometry is concerned with three-dimensional shapes. Some examples of three-dimensional shapes are cubes, rectangular solids, prisms, cylinders, spheres, cones and pyramids.

Cubes
A cube is a three-dimensional figure with six matching square sides.

The figure above shows a cube.

The dotted lines indicate edges hidden from your view.

If s is the length of one of its sides,

the Volume of the cube = s x s x s.

Since the cube has six square-shape sides,

the Surface area of a cube = 6 x s x s

Cuboid

In a cuboid, the length, width and height may be of different lengths.

The volume of the above cuboid would be the product of the length, width and height that is
Volume of rectangular solid = lwh
Surface area of rectangular solid = 2(lw + wh + lh)

Prisms
A prism is a solid that has two congruent parallel bases that are polygons. The polygons form the bases of the prism and the length of the edge joining the two bases is called the height.

A rectangular solid is a prism with a rectangle-shaped base.
The volume of a prism is given by the product of the area of its base and its height.

Cylinders
A cylinder is a solid with two congruent circles joined by a curved surface.
In the above figure, the radius of the circular base is r and the height is h.

The volume of the cylinder is the area of the base × height.

Spheres
A sphere is a solid with all its points the same distance from the center.

Cones

A circular cone has a circular base, which is connected by a curved surface to its vertex. A cone is called a right circular cone, if the line from the vertex of the cone to the center of its base is perpendicular to the base.

Pyramids
A pyramid is a solid with a polygon base and connected by triangular faces to its vertex. A pyramid is a regular pyramid if its base is a regular polygon and the triangular faces are all congruent isosceles triangles.
