Teaching 21st century style

Today was a productive day.  I am glad that TES is making lots of effort to become one of the best school in Colombia. Today I got a mail from the IT administrator about the new resource called Discovery education. Other resource which the school has got is brain pop. I explored this a little bit and its very interesting though elementary. I think over next few days i will be spending a lot of time on brain pop website. There is also myimath which is fun because it lets you assign homework online and get it graded automatically. I enrolled myself as a student and did the assignment and it was great.

Perks of teaching

I have been using Geogebra for a while but it was not until today that I noticed the numerous features that have been added to it. The other day I was talking to Piyush and he mentioned that he was taking some online training on Sketchpad. He has been a sketchpad user for a long time and was gaga about its new features. I like how the geogebra has now integrated the spreadsheet feature and input capability which allows for a limited symbolic capability. There are now tons of library functions too. I found out one on prime factorization. There is still lot to discover and I am planning to introduce it to my students so we can together explore its growing features.

Freedom of speech

  I think the movie makers are having the last laugh. They achieved what they wanted and the more people riot. The easier for them to prove their point. We bloggers and everyone is scared to use the word for infuriating these people. recently posted a hilarious video of different founders engaged in a lasvicious orgy. They and the artist knew that it will be taken in playful spirit as long as they don't include THE RELIGION. Makes you wonder if the prediction that in future there could be ban on following it could become true. Well its for other sane people to decide how much longer can we pander to this insanity.

Partitioning of Natural numbers

Today in my grade 7 I introduced the idea of partitioning of numbers. We talked about how different ways one can partition natural numbers. The simplest one are {1,prime,composite} and {even,odd} but one can also partition natural numbers as {even factors, odd factors} and this classification is equal to {square numbers, non square numbers} The one example which brings to life this concept is the celebrated problem of locked and unlocked rooms.
