Irfan view..a freeware

Today, I am going to share with all of you, how I used Irfan view in my classroom teaching of mathematics. The students were to perform a mathematics activity in class IX. In place of dictating them the procedure in steps, I showed them a slide show of pictures showing the steps. The students were asked to observe the slide show . Then I had a discussion with them , regarding the steps which were shown to them through pictures. They were able to tell the mathematical concept hidden in the pictures. This way, induced brainstorming and resulted in a better learning. During the class the students were deeply engrossed in watching the show. After this, they did hands on activity with the required material.

Fascinating technique

If you want to multiply any number with 9, 99, 999, so on

Consider the following examples
Example 1
99 X 42 = 4158

Step 1 Subtract 1 from 42, we get 41
Step 2 Now, Subtract 41 from 99, we get 58

Answer is 4158

Example 2

Step 1 343 – 1 = 342
Step 2 9-3 = 6, 9-4 = 5, 9-2 = 7

Answer is 342657

Audacity...for voice recording

In mathematics it is mandatory for the students to make a project. This time ,with one of the groups, of my class IX students, I decided to gave them a podcasting project . They were asked to prepare a discussion on utility of mathematics in surroundings and record the same using Audacity.Since the students were not familiar of the software, firstly I trained them on how to use it.Then they recorded an interview (kind of a discussion) .It was an enriching experience for me and the students as well.
The students find it quite interesting.
I would like to thank CII Shiksha for training the teachers on using such tools which are helping us for creating a difference in the classroom
Audacity is free, open source software for recording and editing sounds.

Teaching fractions e way

Its a great pleasure sharing with you about a very interesting and useful content for the students of age group 5-12 years.
Teaching and learning about fractions is an integral part of mathematics. What if this topic is taught and learned in a different way i.e. e way. This topic is a part of EFK Content and it is explained so well that the students not only learnt the concept but also were talking about the presentation as well. The topic has been related to composing music using fractions. It is so interesting that while learning there is enjoyment and thrill involved. This way of teaching and learning has made mathematics learning very comfortable for the students of all types. There is incredible creativity involved.
