<p><span><span>We all have experienced through three dimensions of teaching learning of Mathematics, which are a Mathematics classroom with an instant board, Mathematics laboratory and a multimedia enriched classroom in the school. The 4th dimension is an element of expanded classroom i.e. an online wiki classroom. Technology is advancing with the speed of light. There is no dearth of offline tools, web tools and software which can help a teacher in making joyful learning environments for their students. The use of technology provides opportunities for students to investigate and apply the things they are learning in the classroom. It allows students to interact, create, present and provide a meaningful and purposeful learning activity that is connected to classroom curriculum and goals. </span></span></p>

I came up with the idea of making a blog called Mathematical Randomness. Every two days, or so, I'll go to the World of Mathematics website, read a random article, and come back here and blog about what I read and any questions I have. I think my first blog will be on direction fields. I came up with this idea when looking at an old diify-q book.<br />

using algebra, as it involves factorisation of irrational numbers. <a href="http://en.wikipedia.org/wiki/Compass_and_straightedge_constructions">Geometric Construction</a> is an ancient<br />

I met with the other Pre-Calculus teachers yesterday for a planning meeting. A decision was made to assign a Pre-Calculus project to the students as an end of the year project. We also felt that the students really don't know the unit circle and would like to incorporate the unit circle in the project. I could use some help with ideas for this project. Can anyone suggest some?

I have been talking about homework and practice. How much practice is necessary for a student to really understand how to do something? I have seen research that says 20-30 repetitions will generally store something in permanent memory. Many have posted on the forum/discussion site that they assign 5-10 problems. Is this enough? Is it only once or is it 5-10 related problems for more than one day? I have students that require several days of practice before they get some topics - and even then…

Have any of you used graphic organizers. I use a foldable with my students while teaching the chapter on quadrilaterals in geometry. It seems to help them. I am interested in learning a variety of ideas that any of you have found helpful in your math classrooms.

I am looking for new ideas for extra credit for my students. I don't believe that students should be able to pass only because of extra credit. I have assigned review pages the day before the test, hoping that it would help the students two ways, first with extra credit points and then by improving the test scores. Usually, the A students are the ones who do it. I have considered having students look up videos on You Tube, but am not sure how that would be graded. Do any of you have ideas for…
I am looking for new ideas for extra credit for my students. I don't believe that students should be able to pass only because of extra credit.

Usually, the A students are the ones who do it. I have considered having students look up videos on You Tube, but am not sure how that would be graded.

I am new to this web site and have a subject I would like to discuss.<br />
I am a retired engineer, an MA of Trinity College, Cambridge, having graduated in 1948, and have become interested in the way children are taught numbers rather late in life.<br />
This came about as a result of trying to a help an eight year old in the village who had lost his way mathematically, and had very little understanding of the number system.<br />
I have always held the view that the understanding of an abstract concept can be greatly assisted by the use of a tangible model.<br />
As a result I have produced the most suitable model I could think of, and it helped him a lot.<br />
The model is in essence a helical number line on a tube. The helix starts with zero at the bottom and progresses to the right and upwards around a cylinder, such that there are ten numbers per turn. It is therefore mathemtically correct, being continuous.<br />
As a result the numbers form into vertical columns, all numbers in a column having the same number ending. The largest number is 139.<br />
This was an instant success, and the lad progressed well from that point.<br />
I then supplied some to local schools. The enthusiasm with which the children egaged with it was remarkable.<br />
To cut a long story short, I have personally made nearly 50,000 of these, sold to both schools and individuals. They are now listed by the Every Child Counts program as a "desirable resource"<br />
Given that the feedback I have received from children is universally postive, especially where less able, even dyslexic, children are concerned I am mystified why this resource has not been more widely accepted. There are about 23000 primary schools, and if each of them had just one classroom set of 30, this amounts to nearly 700,00.<br />
<br />
The take up by schools varies from just a single one, to 600 (20 sets)<br />
I have my own thoughts on this, but would like to hear from others. I am prepared to send samples to be anyone genuinely interested. Further details are on my web site <a href="http://www.numdrum.com">www.numdrum.com</a><br />
<br />
I hope I have submitted this note in the right place<br />

You may be writing an argumentative essay to argue for a particular point of view or to may be doing a persuasive essay to explain the steps necessary to complete a task. Either way, your essay will have the same basic format and structure.<br />

<br />
In this article we will provide <a href="http://educationalwriting.net/essays.htm">essay writing help</a> that will teach you about basic structure of an essay. So, here it is…<br />
<br />
Introduction<br />
The introduction section of an essay consists of the main idea of the essay. It shows readers the theory and idea behind all this writing. It may explain why this topic is eligible to write over it. This paragraph also means to capture reader attention. If you can’t convince your reader in this paragraph that your work is worth reading, you will lose your reader in instance.<br />
<br />
Start this paragraph of your <a href="http://educationalwriting.net/essays.htm">essay papers</a> by writing your thesis statement. The main idea of your whole essay will be your thesis statement. You must limit your entire essay writing to the topic you have introduced in your thesis statement. Giving some background info regarding the topic will develop your reader’s interest. You can use interesting facts, quotations, or definitions of important terms you will use later in the essay.<br />
<br />
Supporting Paragraphs<br />
Supporting paragraphs is the whole body of your essay.You have to present the entire concept in there. It may consist of 4 to 5 paragraphs and it needs all your concentration as it’s the theory behind your approach to the selected topic.<br />
<br />
List the points that develop the main idea of your <a href="http://educationalwriting.net/essays.htm">essay writing</a>. Place each supporting point in its own paragraph. Develop each supporting point with facts, details, and examples. To connect your supporting paragraphs, you should use special transition words. Transition words link your paragraphs together and make your essay easier to read. Use them at the beginning and end of your paragraphs.<br />
<br />
Summary Paragraphs<br />
These are the last paragraphs of your essay writing project. It consists of the conclusion for the whole matter and your personnel opinion about it. This section may also contain call for action if needed. You can let your readers decide which concept is right and which one is wrong. You may put some action plan regarding the essay topic.<br />
<br />
Use this paragraph to let your readers have something to think over. Don’t try to force your opinion but make them think over it by giving them some stats or proves.Math Contest for Elementary Studentstag:mathematics24x7.ning.com,2009-09-08:2957074:BlogPost:82952009-09-08T06:19:03.000ZLi K.http://mathematics24x7.ning.com/profile/LiK
