 Dear Children 

I am posting work on operations of Whole Numbers for the two days Saturday and Sunday, as you know that the printer was not working on Friday last. 
Well sums on the worksheets have been organised as easy, medium, difficult and challenging.  If you find the sum easy do them mentally and write the answer.
For the sums which are difficult FOR YOU you HAVE TO SHOW THE WORKING

So let us get cracking these.

We shall be revising Factors Nd Multiples on Monday. Please recall what you know about FACTORS AND MULTIPLES so that we can clear your doubts

Dear Students

I have posted some videos and work on the Math page. The first line of the ist sum will tell you why I did not post yesterday.

Keep practising the sums and bring them to class. You need not do all the sums at one time and show

So do as much as you can do comfortably in one day and try to finish all try to finish all the sums by next Wednesday

I shall also be putting up the template for conecpts today on the LEADERSHIP BLOG. So keep a watch out !

Bye for now

Aniruddha Sir

A. Had a marathon sleep yesterday. Slept at 7 p.m and got up at 5.44 a.m on Saturday. So there was no blog post on math yesterday. Anyway....

1. How many hours did I sleep in all?
2. what will be the time which is exactly in the middle of how long I slept? Draw it on a clock face (analog clock)
3. Can you write the time I slept and I woke up in railway time?
4. If I was travelling by train or by air I would have reached from where to where in the time I slept?
5. Write how long you have slept in railway time?

B. Watch this video. If it does not run for any reason here is the link. https://www.youtube.com/watch?feature=player_embedded&v=9Ek61w1LxSc#at=88 Copy and paste it on you tube to see the video on solving simple algebraic equations.
