Year 6 Maths Worksheet: Reading decimal fractions (1)

reading_decimal_fractions 1

By Year 6 children should have a good understanding of place value, including decimals. Decimal fractions are often best taught in the context of money, but this only covers tenths and hundredths. This maths worksheet looks at thousandths as well. There two main parts: 1. writing the value decimal fractions in words and 2. writing decimals in digits.

Just like whole numbers a digit becomes ten times smaller when it is moved one place to the right after the decimal point, so the digit 6 in 0.467 is 6 hundredths and the 6 in 0.356 is 6 thousandths.

How do you say 2010?

How are you saying the new year 2010?
There seems to be some debate about this. Some are saying ‘two thousand and ten’ whilst others are saying ‘twenty ten’.
‘Twenty ten’ is similar to the last century when we said dates such as 1990 as ‘nineteen ninety’ but few people used this way during the first decade of the new century eg 2008 was not often said as ‘twenty eight’.
Of course the children around here in the south will just say’ twenyten’ because as far as they are concerned there is only one t in twenty (tweny)!

Let us know what you think.

Resource of the Week: Year 4 bar charts

Don’t forget that we have a growing number of resources on data handling, including the bar chart or bar graph. These pages are aimed at Year 4 children. The vertical bars represent the number of people going out on a boat. Each bar is completely separate from the others.

It is important that children get used to naming the horizontal and vertical axes and that these axes should always be named.

The hardest part of interpreting this bar chart involves the number of people shown on the vertical axis. The numbers go up in twenties, but of course there are intermediate values. The number of people on the 11.00 boat is more difficult to read and only a close approximation between 120 and 140 can be made. As it looks just less than half way to the next interval an estimate of just below 130 would be very accurate.

It is important not to just look at the graph but to also make some suggestions as to why the results are as they are. Why did the 12.00 boat have the least number of people on it, but the 1.00 boat have the most?

The second worksheet has similar problems, but the numbers on the vertical axis go up in tens rather than twenties.

Year 5 Maths Worksheet: Square Numbers (1)

square_numbers_1

This maths worksheet uses a 10×10 tables square to show the patterns involved with square numbers. All the square numbers lie diagonally from top left to bottom right.

Once children have seen the pattern and worked out all the square numbers from 1 to 100 it is a good idea to encourage them to learn the numbers off by heart, as if in a list.

This page is probably best suited to year 5 children.

Times tables: 3x table starter

3_times_table_1Here we have a worksheet on the 3x table which is ideal for those children just beginning to get to grips with learning tables. It includes a number line to help those who are still ‘counting on’.

The 3 times table is one of the harder tables to learn, as there is little in the way of pattern, but answers do alternate between odd and even. It is usually learned after the twos, tens and fives.

A good way of checking if an answer is correct is to see if the digits add up to 3, 6 or 9. eg 24: 2 + 4 = 6.

This page can be found in our Four Rules section, under multiplication/tables.

snowflake_1Happy New Year everyone and we hope that 2010 is a great year for maths!

Next week we start the year with a worksheet on the three times table which is ideal for those children just beginning to get to grips with learning tables. It includes a number line to help those who are still ‘counting on’. The 3 times table is one of the harder tables to learn, as there is little pattern but answers do alternate between odd and even.

We also have a page on square numbers, suitable for Year 5, which looks at the patterns of square numbers.

For older students we have a page on working out the value of decimal fractions up to thousandths.

Year 6 Maths worksheet: Converting metric units (2)

y6_larger_units_to_smaller_2This is about as hard as it gets for converting larger metric units to smaller ones. The larger units all include decimals and a good knowledge of multiplying by 10, 100 or 1000 is needed.

As a special treat the last question is really tricky; How many centimetres in 1.9 kilometres. I imagine that there are quite a lot of adults who would struggle with that one, but taken in logical steps it proves to be not so difficult. Find the number of metres in 1.9 kilometres, then find the number of centimtres in that amount. easy eh. It is quite interesting to look at other distances in terms of centimetres: journey home from school, length of a football pitch etc which would make for an interesting investigation.

01.10.01.10.01.10

Well it looks as if the Binary Age is almost upon us and we’ve been waiting a long time for this tremendous event.

Of course 1st January 2010 can be represented as 01.01.10, but New Year’s Day is just the start of something much bigger.

The 1st second of the 1st minute of the 1st hour of the 1st day of January 2010 can be written:

01.01.01.01.01.10

but perhaps even more interesting is a date later in the month: Continue reading “01.10.01.10.01.10”

Maths puzzle: Initial Numbers

initial numbers

It’s the last day of term and snowing quite heavily here so it looks as if there is no school at all for many children. Teachers will not be getting their pressies or having their last afternoon parties!

Oh well, here is a little puzzle for you to contemplate over the Christmas period.

Each number has some initials next to it. Just work out what the initials mean as the numbers are the clue.

For example:

7 D in a W is 7 Days in a Week

Some are these are pretty tricky and a score of 12 is good. Get them all right and you are a superstar indeed.

Answers after Christmas.

Thanks for all your comments and fun this year.
