Scientific Notation and Approximations Bulletin Solutions

Are you enjoying your long weekend? I hope you'd found some time to practise with the exercices I gave you ;)

If you want to check your answers, you have the chance to download the bulletin with all the exercices solved by clicking ¡¡here!!

Also, if you find yourselves into trouble with the solutions (because there's something you don't understand or, maybe, just maybe, because I got confused and copied something wrong...) you can post a comment asking anything you want me to review or explain ;)

We have 4 sessions left before our EXAAAAM. Next Wednesday, you'll learn about Irrational numbers and, finally, next Thursday I'll tell you about rean numbers intervals.

Next week (Monday or Tuesday), I'm planning to bring the laptops to class so I can finally explain you how to create an entry using maths expressions ;)

Here's one of the best videoclips of the last year! ;)

Halloween Themed Session!!

Hi there!

It's been quite nice to find out that you've enjoyed today's lesson  ^_^  I don't want to lie to you; it wasn't an easy one to prepare, but the final result worth the (MY) effort. You happen to be smart students, so I'm sure you all understand that these "special-themed" sessions will only be possible if we keep on working on schedule ;)

So; let me make my point through an example: the better you behave, the less spanking you will get XD. I hope you'll give me the opportunity to try new games/activities from now on. And remember: if you had behaved better, you would've had the chance to experience new and/or different stuff earlier ;P

Enjoy your long weekend!! We'll meet again next Wednesday (one week prior to our next EEXXAAAAAMMMM!!!)

PS: Allo, Andrés...how are you feeling today? Are your multiple diseases & ilnesses disappearing? :)

A SO AESY LESSON

Today we correct the homework first(Andres was ill so there were no shouts of EXAM or HOMEWORK) and then Mario explained us the truncation, overapproximation and round. I look in You Tube a video of that in Barrio Sesamo but i don't find any video becouse it is to easy for them, so i make one for you:

Then we make some activities in the homework sheet and we read a page explaining us that, i think all the people in the class understand the lesson and we behave more propierly. We make the vote of the strike and if the information i have is not wrong, we haven't got school the thursday because we "win" it.We have from homework the activity sheet the teacher Mario give us.

TODAY LESSON

HII CLASSS!

TODAY WE HAVE CORRECTED THE "EEXAAMM!" THAT WE DID THE LAST DAY, IT WAS A LITTEL BITE DIFFICULT MARIO! YOU AND YOUR TRAPS IN THE EXERCISE 4!
MARIO YOU HAVE A LOT OF PACIENCE, BUT HAVE A LITTLE (PIEDAD) OF US AND DO THE TRUE EXAM NO SO DIFFICULT PLEASE, CALSS WE HAVE TO TALK LESS!
NEXT WE PLAY A MEMORY GAME, IT WAS FUN AND EXCITING, I LIKE THE THINGS THAT WE DO, NO BORRING EXERCISES AND THAT THING...¡!

I WANT YOU TO SHOW THIS VIDEO: AJJAJA IT IS VERY FUNNY. YOU HAVE TO STUDY TO TRY TO DON´T HAVE THIS JOBS IN THE FUTURE. ENGOY IT;))

Sorry fans of DJ Santonio and DJ Mi Primo, i thought that andres have upload the remix but he didn't because was ill. Here you have the video:

I know the video is a patatoe but concentrate on music that is bad but not so much

Scientific Notation

Hi class!!! I don't know very weel what I have to do but I go to start.

Today in class we studied the Scientific Notation.

A number with a scientific notation has always two parts:

- A decimal number n verifying that _

- A power of 10 with an integer number as exponent.

For example: 300.000.000= 3·108

Then we have done some exercise about the scientific notation,that are: Page 42 (13-15)

13.a)493000000= 4'93·108 d)12'00056= 1'200056·10

b)315000000000= 3'15·1011 e)253=2'53·102

c)0'0004464= 4'464·10-4 f)256'256= 2'56256·102

14.a)0'247·108/ 2'47·107

b)24'7·108/ 2'47·109

c)0'247·10-8/ 2'47·10-9

red= important things

blue= the exponents

I think that that's all:))

I put some videos to entertainment:P
