Division
Over the last couple of weeks we have been learning how to use single digit divisor and whole number division. After we have mastered that we will be doing double digit divisor as well as decimals division and fractional division.

Rounding up and down
One of the most important tasks you have to be able to perform competently, on a daily basis, is estimation of an answer. One of the skills which enables us to do the estimation with relative speed and accuracy is "rounding up and rounding down".
The same rule applies to each place value column in a numeral regardless of whether you are changing to the nearest ten, hundred, thousand etc.
Look at the digit to the right hand side of the place value you're rounding to; if it's 5 or greater add one to the"rounded to" column; if it's less than 5 leave the "rounded to" column as is. eg 45 x 54 becomes 50 x 50.
Multiply the digits ignoring the zeros, then add the total number of zeros in both the factors to the right hand end of your answer. eg 45 x 54 becomes 50 x 50 = 5x5 = 25 now add the zeros and the estimation is 2500.

Quote for this week (27/2/2012)
"There are 10 kinds of people in the World who understand binary facts, those who do and those who don't"

It's Good to see you now accessing the blog, and it's even better to see some of you sharing it with your parents. This week we are looking at Roman Numerals.

When making a comment (pupils) please make sure what you write is brief and adds value to the topic.
Motivation
Today we discussed extrinsic and intrinsic motivation. Can your child simply explain the difference?
My belief is that to be the " best you can be" you have to be be intrinsically motivated.
What are your thoughts?

Times Tables
Current homework is all about extending tables knowledge and increasing speed of computation.
These tables not only include times tables up to and including 12x, but also include a set of equivalence tables.
Please ensure your child is spending time on coming to grips with these by having a family member doing some "home" monitoring and testing. A recent test showed a number of the class achieving good success whereas others need to make a lot of effort to improve knowledge to an acceptable class standard.
The catch cry for 2012 is KEEP UP or CATCH UP!

Fibonacci
I have just read the story Fibonacci's cows to the class and we have studied Fibonacci's famous number sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144_ _ _ _ _ Your child has been asked to continue the pattern for the homework exercise below.
What I have asked them to do is to continue the pattern, giving the next ten numbers in the sequence. They are then to use a calculator to divide the numeral before into the numeral after and write the decimal answer to three decimal places. Having done this we will analyse the results as a class.
If you've read the "Da Vinci Code" you may recognise the above sequence. Few people realise however that Fibonacci's greatest contribution to the Western World was to introduce the Hindu- Arabic number system which contained the digit zero. Until the 11th century European's were not able to create a place value because of it's absence. Mathematicians such as Pythagoras knew of its existence but because of its powers refused to utilise it.
Had we accepted its existence when first discovered, it is said that technology now would be 2oo years advanced.

About this Site
Welcome to the Primary's Year 5/6 extension maths site.
The function of the blog will be to include families in the students current learning programme,to allow students to share their knowledge with you, and to make appropriate contribution where necessary.
The possibilities for use of a blog are many and varied, and you will see "additions" and "subtractions" as the year progresses, and the blog is reviewed and revised.
Entries may not be on a daily basis but should occur at least once a week.
