Reading a ruler is a basic and an important measurement skill, which most of us are well aware of. But there are many people who find it a intimidating task. Ruler is a standard measurement tool that enables us to read measurements in either the metric system (meters, centimeters, or millimeters) or the English (miles, yards, or inches) system. There are simple instruction on how to read ruler. A metric ruler mainly deals with centimeters (cm) and millimeters (mm) and no fractions are involved. Reading a ruler that uses the English system or inches is apparently a bit difficult and requires a basic knowledge of fractions.

How to Divide Decimals
Working around with decimals may be a little taxing and when students are faced with the question of how to divide decimals, they realize that they have to exercise their brain more than ever before. However, taking a step by step approach to the problem in hand, can make dividing decimals easy. Here is how...
Decimals are used to provide greater precision to numerical value of a quantity. Along with this benefit comes a challenge, which is the fact that carrying out mathematical operations are more difficult with decimals as compared to whole numbers. When it comes to how to divide decimals, then the scenario becomes all the more complicated. It is so because division is the most complex among, all the four basic operations in mathematics. In fact, one needs to use successive subtraction to carry out a division. But problem solving, which involves division of decimals, can be made easy by ensuring that the divisor is a whole number. This can be done by shifting the decimal, so that, the divisor becomes a whole number. However, to avoid the ill-effects on the result of the problem, the dividend also, needs to be altered and balanced accordingly. This is the case if the divisor is a decimal. But first let us learn how to divide a decimal when the divisor is a whole number.
How to Divide Decimals: By a Whole Number
This is the easier of the two cases of division of decimal. When the divisor is a whole number and the dividend a decimal, then ignore the decimal point of the dividend. Now the problem becomes a simple one, which is a division involving whole numbers only. Work out the problem using the regular long division method. Once the quotient is achieved, place a decimal point with as many numbers to the right, as originally was in the dividend. Lets understand this process with an example:
Lets say we have to solve 7.9/4 to find its quotient. Follow these steps for solving the problem:
Step 1: Ignore the decimal point in the dividend. Now your problem becomes 79/4.
Step 2: Carry out the division with the regular long division method. The answer is 19.75.
Step 3: The dividend had one digit to the right of the decimal point. So, we have to ensure that we shift the decimal so that there is one more digit to its right. Hence the answer is 1.975.
How to Divide Decimals: By a Decimal Number
If the divisor is not a whole number, then we have to move the decimal point over as many places as it takes, to make it a whole number. The same has to be done with the dividend. If the dividend is also a decimal number then move the decimal point over to as many places as you did in case of the divisor. Add some extra zeros to the dividend, if you have to. If the dividend is not a decimal number, then just append zeros to it, number of which should be equal to the number of places that you have shifted the decimal in the divisor. Let 's understand this with this example:
Lets say we have solve 4.25/ 0.125 to find its quotient. Follow these steps for solving the sum:
Step 1: To convert 0.125 to a whole number, you have to shift the decimal point to over three digits to right. Then you get the whole number 125 as the divisor.
Step 2: Now move the decimal point in the dividend 3 places to the right. But there are only 2 digits to the right of the decimal in this case. Hence, you will have you append a zero to the end of the dividend and then shift the decimal 3 digits to the right in the dividend. Hence, the dividend now becomes 4250. The division that you have to solve is now 4250/125.
Step 3: Now carry out division as you normally would. The answer is 34. More information on:

Math is a very intriguing subject. Either a student completely understands the subject else it can make no sense to them. It is the task of the elementary school teacher that such an important subject be taught with exceptional care so that it does not become a nightmare for the students as they grow up. One of the best ways to teach students the subject is via simple games as it will hold their interests better and will make concepts clearer. Example math games is The Astrolabe Game and Guess the Sequence.

There was the mathematics lecturer is teaching their students count up to a million. The first meeting, hear the voice of the students counting: 4 596, 4 598, 4 599, … .And the next meeting, hear again the voice of students counting: 13 127, 13 128, 13 129… . the purpose of this mathematics lecturer shows about the modern way of introducing a certain concept. First of all, make the pupils aware of how huge the number million. Secondly, they have great satisfaction in being the first. So far, nobody has counted up to a million! Thirdly, when testing whether pupils can count up to a million, The statement: "I can count up to a million" is worthless until it is proven experimentally, i.e. by the process of actually counting".
Comment :
With this article, I am feeling a bit confused, such as this statement,” I can count up to a million” is worthless until it is proven experimentally by the process of actually counting. I think this statement shows that if I can count up to a million, it is unuseful. Am i right??. If it does, why their pupils must count until a million (such as explanation of this article)?.
With the explanation that given this article, we can know that in 50 minutes, would count up to 5 000. In other word, in 100 minutes we can count up to 10 000 until in 10 000 minutes or ± 16 hour, we can count up to 1000 000 ( a million ). So, who want to do it ? During 16 hour just count up to million. I think nobody and as we know that the numbers were getting longer. It’s the entertaining article..

How to Teach Classroom Mathematics
The entertaining article on teaching methods of classroom mathematics. Some years ago, I got appointment as a Head of Pre-Entry Science Course Department at the Technical University in Balgravia. The Department enrolled the best students from different high school of the country. The objective of the Department was to find students’ gaps in their knowledge of science subjects and upgrade them to university standards. It was pleasure to work in an exotic country on such challenging issues and for such noble goal.
Once, when I passed by a classroom where mathematics was being taught by a colleague, I heard the voice of the students counting: 4 596, 4 598, 4 5999…At that time, I did not pay much attention to it. But after three days, from behind the doors of the same classroom, I heard: 13 127, 13 128, 13 129…
"My friend", I asked Mr. S. soon afterwards on the corridor, "what is happening in the classroom during your math lessons?" "Well, my students are counting up to a million, he answered." "Hmm," I muttered and went away.
Then, at the staircase, I realized the meaning of his words. I went to my office. Looking at my wristwatch, I counted up to one hundred. I picked up a calculator. I computed that in 50 minutes, they would count up to 5 000, in a week (5 lessons) to 25 000 and at the end of the school year, they would not even reach 800 000 because of holidays and the fact that numbers were getting longer!
I summoned Mr. S. "Do you realize what you are doing with your counting?" "This is a modern way of introducing a certain concept. First of all, I make my pupils aware of how huge the number million. Then, secondly, we have great satisfaction in being the first. I believe, so far, nobody has counted up to a million! I expect the class to be in the "Guinness Book of Records" and thirdly, I am testing whether pupils can count up to a million! The statement: "I can count up to a million" is worthless until it is proven experimentally, i.e. by the process of actually counting". I got upset. "Enough is enough!" I shouted. "I order you to teach according to the syllabus!"
Next day, stealthily, I approached his classroom. The pupils were reciting: 17 999, 18000, 18001… I decided to fire Mr. S. Discreetly, I let my superiors know that Mr. S. was probably lunatic. The message was spread. The university community decided that I was against the introduction of modern teaching methods, that I do not understand the outcome based education and that I felt personal animosity towards our colleague. My two-year contract expired and was not renewed... I left the university
After a month's time, I came back to the Department to visit my friend, the English tutor. From all the classrooms where mathematics lessons were conducted (not only from the classroom of Mr. S.), I heard the voices of the students counting: 277 238, 277 239, 277 240…
Math Magician Games
Math has been a part of everyone's life and plays an integral role in our day-to- day activities. Learning math can be an interesting as well as a boring subject depending on how well you grasp its basic concepts. However, today learning math and most importantly enjoying it, has taken a priority, especially among the kids. So read on to learn more about math magician games and tricks.
When I was in school, math wasn't exactly my cup of coffee (Why should it be tea always?) I used to burn my lips, every time I thought of it. For me, math has been a M- Mind Boggling, A- Agonizing, T- Tiring, H-Horrible subject. I used to get confused by the formula, the theorems and what not. Algebra!!! I never understood why they used x, y and z every time when there were so many alphabets remaining. It was a never ending agony, a traumatic experience. Pythagoras theorem looked so meaningless to me. I wonder why he measured a triangle, when we don't have any use of it in our daily life. Well, I could go on with my litany of complaints. However, these days, kids enjoy math, thanks to several math magician games available on-line and off-on-line.
Kids adore magic. So it is a good idea to interlink the basic concepts of addition, subtraction, multiplication and division with magic to teach them different math magician tricks and puzzles to make the subject interesting. Introduce kids to a whole new world of math problem solving. The basic concept is 'not to do different things, but to do things differently'.
Math magician games for kids can include solving word problems. Word problems range from being very simple to very complex. Involve real life situations like buying and selling, that include the use of the mathematical operations like addition, subtraction, multiplication and division. Simplify and teach them the right use of the concept of BODMAS, a basic concept, which every child would find useful in everyday life later in their lives.
Math Magician Games - Class activities
You can use the following math magician game in class where you can make the kids believe that math is a tricky and interesting subject. Here is the math magician trick:
1. Divide the students into different groups. Pick out a student from each group and then make him or her choose any number from 1 to 20
2. The students must not disclose the number they have chosen
3. Now tell them to multiply the number by 2. But make sure they do the calculations in their mind
4. After they have finished make them add 10 to the answer. Then ask them to divide the result by 2
5. Let them subtract the original number they had chosen from the result of No.4
Watch their awed expression when you announce that the final result for all
of them is 5.
