Can you do it in three different ways? There are nine levels to this online challenge and a virtual Transum Trophy available for each level. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures.

It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables. Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport.

Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. If you found this activity useful don't forget to record it in your scheme of work or learning management system.The numbers in the Red Squares form the 3x3 magic Square. The numbers beside the Red Squares show the totals for each row. The horizontal and vertical totals are to the right and below in green squares.

### Magic Square Game

The other, blue, squares show the diagonal totals - including all of the "broken diagonals". You can make your own Magic Square in two ways. Try both methods:. This reveals the underlying structure of a 3x3 Magic Square.

Actually, all 3x3 Magic Squares have an identical structure.

## Magic Square Puzzle

And, if the same numbers are used, e. In the 3x3 square, it is impossible to make all of the diagonals "magic". The Main Diagonals are "Magic" when you put the middle value the "3" and the "1" in the center location in their sequences in the top array.

If you put these "middle" numbers in other positions, then one of the broken diagonals becomes magic instead. The magic square below is the sum of the patterns that these numbers make. Use them or enter new ones and then click To understand the structure, move the mouse over the blue arrows and wait.

Look at the pattern that your selection produces in the square below The Bottom Right number under the blue down arrow above is the first number in the sequence for the square. By convention it is "1", but any number can be used. If you change the bottom row above and try using "3,2,1,0" instead, do you get the same result as "2,1,0,1"?

You can also try experimenting by writing in your own numbers in the red squares. To see the totals, press The numbers at the top and the left are the sums for the diagonal rows - including the broken diagonals. Use them or enter new ones and then click. To understand the structure, move the mouse over the blue arrows and wait. Look at the pattern that your selection produces in the square below. The Bottom Right number under the blue down arrow above is the first number in the sequence for the square.The constant sum in every row, column and diagonal is called the magic constant or magic sumM.

In this post, we will discuss how programmatically we can generate a magic square of size n. Before we go further, consider the below examples:.

Did you find any pattern in which the numbers are stored? In any magic square, the first number i. Let this position be i,j. The position of next number is calculated by decrementing row number of previous number by 1, and incrementing the column number of previous number by 1.

At any time, if the calculated row position becomes -1, it will wrap around to n Similarly, if the calculated column position becomes n, it will wrap around to 0.

Two types of degreasersIf the magic square already contains a number at the calculated position, calculated column position will be decremented by 2, and calculated row position will be incremented by 1.

Load Comments.Magic squaresquare matrix often divided into cells, filled with numbers or letters in particular arrangements that were once thought to have special, magical properties.

Originally used as religious symbols, they later became protective charms or tools for divination; and finally, when the original meanings were lost, people considered them mere curiosities or puzzles—except for some Western mathematicians who continue to study them as problems in number theory.

Arranged both vertically and horizontally, the meaningless phrase reads through the centre TENET, thus forming the two arms of a hidden cross. Examples of this square from the 1st century ad were found in the ruins of Pompeii, and it was still employed during the 19th century in Europe and the United States for fancied protection against fire, sickness, and other disasters.

Otherwise, numbered squares have always been far more significant, particularly in China where they may have originatedthe Arab world, and India. In the arithmetical magic squares, the numbers are generally placed in separate cells and arranged so that each column, every row, and the two main diagonals can produce the same sum, called the constant.

A standard magic square of any given number contains the sequence of natural numbers from 1 to the square of that number. Thus, the magic square of 3 contains the numbers 1 to 9. If these nine numbers are simply listed in three rows or three columns, they form the natural square of 3. Magic square.

You can make your own Magic Square in two ways. Try both methods:. Observe the numbers in the Magic Square. This reveals the underlying structure of a 5x5 Magic Square. One pattern represents the large numbers and the other the small ones. All 5x5 Pan-Magic Squares have a similar underlying structure.

By changing the order of the numbers in these two sets of numbers, distinct squares are possible. Reflecting, rotating, and translocating, each square multiplies this by to give a grand total of 28, different 5x5 pan-magic squares. This method always produces "Pan-magic" squares, i.

There are so many ways to use this square it seems like Magic. A zinc adjustable handle provides tool-less angle adjustments.

This allows you to use the square to hold material offset to each other. Tighten the tabs onto the front or back of your square and you can immediately get to work. Sure, there are different jigs out there, but can they line your material perfectly in seconds? Install our edge alignment pins on any square to create a large, overhanging edge which can be used to index the square on a different plane. Depending on the square, this allows you to create edges which are 90 degrees perpendicular45 degrees, parallel, and even 60 and 30 degrees from the edge.

Black Oxide, blackening, oxidizing, oxiding, black passivating, gun bluing. The black oxide process is a chemical conversion coating. This means that the black oxide is not deposited on the surface of the substrate like nickel or zinc electroplating.

Instead, the black oxide coating is produced by a chemical reaction between the iron on the surface of the ferrous metal and the oxidizing salts present in the black oxide solution. These oxidizing salts include penetrates, catalysts, activators and proprietary additives which all take part in the chemical reaction. The result of this chemical reaction is the formation of black iron oxide, magnetite Fe3O4on the surface of the metal being coated.

Here's all the main ways to use the square:. Tips For Variable Angle Settings. When using the Magic Square as a variable angle tool, each angle you set is creating two useful sets of angles for you, the main angle and a complimentary second angle acute and obtuse angles. This means the squares always give you two options on how to hold your work piece at a given angle. The most accurate way to get an angle is to use a digital protractor.

A scale is not included due to complexities in getting an accurate, high quality scale made.
