Free Y6 maths worksheet: reflective symmetry from mathsblog.co.uk
By the end of year 6 children should know and be able to read, write and use the following quite tricky words:
Mirror line, line of symmetry, line symmetry, symmetrical, reflect, reflection, translation, axis of symmetry, reflective symmetry.
Also they should be able to test for symmetry using a mirror and by folding.
Children should be able to sketch the reflection of a simple shape in a mirror line where none or only some of the edges of the shape are parallel or perpendicular to the mirror line.
This might seem easy, but actually prove problematic to many children. A small mirror is a great help with this and children are supplied with one in their SAT tests if such a question comes up - and they do seem to be very popular.

Free maths worksheet from mathsblog.co.uk: ordinal numbers wordsearch
Whilst young children are not expected to know the term ‘ordinal numbers’ they are expected to know and understand terms such as first, second, third etc.
This is a simple wordsearch using these terms. All the words can be found either going across or down – there are no diagonals. It is good practice to help with reading and writing these words.
4 times table worksheets from mathsblog.co.uk
The 4 times table is a ‘middle of the road’ table which many children never get a secure recall of. It is, of course, double the two times table and all the answers are even.
Remember the danger is that some children are taught that they only need to count up the answers: 4, 8, 12, 16 etc. However, this is not very helpful if a child needs to know what 4 x 9 is; they do not want to have to go through the whole counting up in fours 9 times to get the answer. The whole idea of tables is that they are learnt, off by heart. To do this it is essential to say them out loud:

Internet access for low income families
The Government is beginning to put into practice its scheme to ensure that all school age children have computer access at home. They are piloting the scheme in Suffolk and Oldham in February by providing grants to pay for one computer, software, internet access and 3 years’ technical support. It will be aimed at those families on income support.
Jim Knight, Schools Minister says that having home access to the internet is fast becoming essential. He goes on to say,
“Schools are revolutionising how they educate faster than many families realise. There is no substitute for good classroom teaching but day-to-day school work is increasingly web and computer based - and it is clear that students get better results where technology is used effectively at home to study, research and communicate.”
By the autumn of 2009 it is hoped to have the scheme operating nationwide.
Maths vocabulary from mathsblog.co.uk
Some quite difficult vocabulary is introduced in Year 2. We shall start with the recommended new vocabulary for Counting and Place Value.
Words to do with Counting and Properties of numbers are:
hundreds thousand
threes fours fives sixes
sevens eights nines tens
twenty-first twenty-second etc
tally multiple of sequence continue predict rule
one-digit two-digit three-digit
place value stands for represents exchange
Much of the new vocabulary will be concerned with the introduction of multiplication and division, so a word like threes will be used in a question “How many threes in six?”
Remember that new vocabulary should not be introduced in isolation, but in suitable contexts.
(Taken from Mathematical Vocabulary Book DfEE)
Below is a link to these words written so that they can printed be displayed.

Moving towards standard written methods of addition: maths worksheet from mathsblog.co.uk
Just one page is not enough for children to become confident with a method, so I have included here a second maths worksheet which uses the ‘moving towards standard written methods’ of 2-digit addition.
With this method the units are added and placed below the sum, mmaking sure the units are in line and the ten is placed in the tens column. The tens are then added and placed below. The crucial concept here is to remember that it is tens which are being added, so there will be a zero in the units column to ensure that the tens numbers are kept in line. Finally the two answers are added.
This method shows clearly what is happening and avoids the potentially troublesome ‘carrying’ of the tens when using the standard written method.

10x table maths worksheet from mathsblog.co.uk
The 10 times table is often the second that is learnt by children, usually after the two times table. The reason for this is that it appears to be easy. Before attempting to learn the table children should have had plenty of practice counting up and down in tens.
However, there is a great danger with the ten times table in that many children are told to just ‘add a nought’ when multiplying by 10. This is disastrous to later understanding of place value and does not work when multiplying a decimal by 10 (eg 2.3 x 10 is not 2.30, it is 23).
The whole idea of tables is that they are learnt, off by heart. To do this it is essential to say them out loud:
One times ten is ten
two times ten is twenty
three times ten is thirty
four times ten is forty
five times ten is fifty
six times ten is sixty
seven times ten is seventy
eight times ten is eighty
nine times ten is ninety
ten times ten is one hundred.
Below are two free maths worksheets on the 10x table.
Free maths worksheet from mathsblog.co.uk
A good understanding of place value is needed to partition a number. Always think of large numbers in blocks of 3: hundreds, tens and units: then hundreds, tens and units of thousands: then hundreds, tens and units of millions. So 456 456 456 is four hundred and fifty six million, our hundred and fifty six thousand and four hundred and fifty six.
Partitioning a large number such as 2 345 678:
2 345 678 = 2 000 000 + 300 000 + 40 000 + 5 000 + 600 + 70 + 8

Don’t be surprised if your daughter seems to be doing better at school than your son!
It has been a fairly well known fact that girls do better than boys at all levels of education from the age of the first SAT tests at 7 up to higher education.
A new report has just come out which suggests that this is true at an even younger age. A study from the Institute of Education in London (part of the Millennium Cohort study) says that girls are two months ahead of boys in verbal, non-verbal and visual skills at the age of 5. They even suggest that girls are doing better than boys at the age of 3! Read the rest of this entry »
