I showed this video on History of Mathematics to my students . They were excited to see what they read in their textbooks. Visualisation plays an important role in explaining a concept . Through these knid of videos learning has become exciting . Students ask related questions leading to creative discussions .

Probability is one of my favourite area for exploration. I love to do probability experiment with my students of class 10. In my earlier years of teaching I used to actually experiment using a dice , a pair of die ,rolling them 200 times , 500 times. It was time consuming. But now, with the available applets on web, it has become easier and far more interesting . One may take as many readings on just clicking a mouse. Here is list of my favourite Applets.
- Birthday Applet - Try it… In a group of 23 (or more) randomly chosen people, there is more than 50% probability that some pair of them will have the same birthday. For 57 or more people, the probability is more than 99%, tending toward 100%.
- Tossing a coin Applet - Toss a coin as many times and calculate the probability of getting a Head or a Tail.
- Spinner Applet - An interesting one to experiment on probability of spinning.
- Racing Game with two dice
- Marbles Applet

I am glad to share about a new network of upcoming e teachers of India http://eteachersofindia.ning.com/ . Bringing e teaching is not so easy. Teachers have to learn all concepts in new ways…e ways. I believe if we learn and share together , any big project can be handled with ease.
I am proud to put this badge here.

In class X C.B.S.E. Mathematics syllabus, the concept of Probability is introduced for the first time to the students. The students more or less cram the idea and do the questions using the formula. But when they actually experiment on probability they ask the questions like I tossed the coin two times and both the times head appeared so the probability of getting a head is 1 instead of 1/2.
I think this way they will not correctly learn the actual probabilty concepts. To make them understand the actual meaning and interpretation of probability,in my classroom teaching of probabilty I have used the probability Applets given on the web for generating the readings.
E.g. if a coin is tossed 100 times then how many times a head appeared and how many times a tail appeared.Then I ask my students to compare the results with the results which they have learned.
And if we increase the number of throws to 200, 300 or more then the students can actually learn the correct interpretation of probability.
I have designed various probability problems. I am sharing some of them.
Throw a pair of die 200 times .Note down the readings. Calculate the probability of the following
getting sum more than 8 on both the dies.
getting a multiple of 3 on first die .
getting prime number on both the dies.
getting an even sum
I have used the following links for generating the readings.

Story telling is a strategy which could help math teachers to bind students close to mathematics.There are various true tales/anecdotes of mathematicians which could add a long lasting impact on students to explore mathematics deeply. In my free periods as well as in class teacher period or in House meetings I am using this strategy of story telling.
Here I am sharing some incidents about a famous Mathematician Gauss.
Gauss was a child prodigy (a teenager who acclaimed success at a young age), of whom there are many anecdotes pertaining to his astounding precocity while a mere toddler, and made his first ground-breaking mathematical discoveries while still a teenager.
At the age of three he corrected, in his head, an error his father had made on paper while calculating finances.
Once in primary school his teacher, J.G. Büttner tried to occupy pupils by making them add up the integers from 1 to 100. The young Gauss produced the correct answer within seconds by a flash of mathematical insight, to the astonishment of his teacher,J.G.Buttner.
He added the integers from 1 to 100 in the following manner
S=1+2+3+4+————-100
S=100+99+98+————1
2S = 101+101+101+————-101 (100 times)
S= 10100/2 = 5050.
Gauss had realized that pairwise addition of terms from opposite ends of the list yielded identical intermediate sums: 1 + 100 = 101, 2 + 99 = 101, 3 + 98 = 101, and so on.
If you are sharing some real stories of mathematicians in your classrooms ,Please do share.

Fear of solving word problems.
There is a fear of solving a word problem in mathematics among the students .About 80% of the students try to avoid it during the examination. Once I had a survey in my class and I asked the students to solve two word problems from the chapter mensuration in class X.
30% students do not even read the problems.
35% do not understand what is being asked in the question?
15% tried to form correct equations but failed.
20% attempted the questions correctly.
There is no way…to skip word problems. But yes we can make solving word problems interesting for students. It is a challenge for a teacher to add a creative element to a dullest and boring work. The first effort made by a teacher could be to inculcate in students an attitude of doing/learning all kinds of problems which are essential for them. The second and the most important aspect is visualizing a problem. If the students visualize a concept, it helps them to learn/grasp the concept quickly. We can use the resources available on the web for making them visualise the concept.
