Lots happening in school this week - including the first of our P.E. sessions with the coaches from Arsenal and the first Science Investigation Day of Autumn Term.
MATHS
In maths this week, both groups will be reviewing factors and multiples. We will be revising things like...
What is a factor?
What is a multiple?
How many multiples of 4 are there between 223 and 230?
What is a prime number?
If you want to get ahead this week, take a look at these tests of divisibility:
A number is divisible by 2 if the last digit is 0, 2, 4, 6 or 8.
A number is divisible by 3 if the sum of the digits is divisible by 3.
A number is divisible by 4 if the number formed by the last two digits is divisible by 4.
A number is divisible by 5 if the last digit is either 0 or 5.
A number is divisible by 6 if it is divisible by 2 AND it is divisible by 3.
A number is divisible by 8 if the number formed by the last three digits is divisible by 8.
A number is divisible by 9 if the sum of the digits is divisible by 9.
A number is divisible by 10 if the last digit is 0.
These are borrowed from the following site:

Some of them you may know; some of them you may not. Test them out to see if they work and try to remember them. They're another brilliant trick you can put in that maths-toolbox you keep in your head.
Ok - back to prime numbers - each of which as you know has only two factors ('1' and itself). Prime numbers are amazing things once you get to know a little bit about them! Have a look at these fascinating facts...

"What no maths games this week?!" I hear you cry. Oh go on then... this game is called Numbercop:

It'll help you to know your primes and multiples. Click on the link, enter a name and then select 'prime numbers' or maybe a multiple you want to test yourself on. You'll figure out the rest!
ICT
We'll be continuing learning how to put together an exciting Powerpoint presentation this week in ICT. We'll be programming some buttons so that our end-user can go backwards and forwards through the slideshow as they please.
If you want to make a cool looking button to copy and paste into your slideshow, take a look at this site. You can use it to make some very nice shiny buttons with your own text on them:

A couple of sites you might find useful if you're bored with WordArt:
http://www.graffitigen.com/
http://www.glittermaker.com/
Make some fabulous text and get copying and pasting (to copy the text that you generate, 'right-click' on it and select 'copy', then paste into your presentation).
Have fun!
**STOP PRESS!**
News just in! First pictures of salt crystals grown in last week's homework have arrived this afternoon from Kelsen. Thanks Kelsen! Here they are:

at last week 4 is out i want to learn lots of things about prime numbers
keep it up Mr h
FINELY WEEK 4
the ict graffiti thing is cool i used it for my blog
This numbecop game is very cool!
Dupe
I know how you can tell if a number is a multiple of 9 just by going to numbercop thanks mr h!
