Resource of the Week: Weather chart

It’s lovely and sunny here and the Olympics are well under way, so what better than a weather chart to brighten the day even further!

This worksheet shows a weather graph of the average maximum and minimum temperatures for each month of the year for London and shows just why August is a pretty good month to hold a sports competition. It is typical of many found on weather sites on the internet, holiday brochures and newspapers. It is well worth reminding children that a graph should always have a clear title, and the axes labelled.

Some children have problems interpreting the scales on graphs when they don’t go up in single figures so it is important to point out what the temperature scale is. Most suited to year 5.

Resource of the Week: Standard metric measures

With the Olympic Games just beginning now is a great time to brush upon those standard metric units of measurement. No longer do athletes run 100 yards or a mile: in fact the Olympics have always been metric and it is the system that all children are taught in school.  By Year 4 children should be quite familiar with the main metric units of measurement and should know the following:

1 kilometre = 1 000 metres

1 metre = 100 centimetres

1 metre = 1 000 millimetres

1 centimetre = 10 millimetres

1 kilogram = 1 000 grams

1 litre = 1 000 millimetres

It is a good idea to tell children that mille is Latin (and French) for 1 000, not one million!

This page is a good check of understanding this and getting children to use these units of measurement.

Ordinal numbers maths worksheet

Once children have got a really good knowledge of numbers they can start to look at ordinal numbers. 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 language can be developed during the playing of games whilst discussing who should go first, escond 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 as some of them are quite tricky.

Resource of the week: Maths puzzles

With half term upon us and most of the serious testing and examining over for another year, now is a great time to try out some maths puzzles which lead to a better knowledge of the subject and an improvement in logical thinking.

There are some great games and puzzles on the site for all aged children and they have been organised in broad area of difficulty. The ‘easy peasy’ section is geared towards young children and the word searches are all on the themes of maths vocabuary suitable for that age group. The maths wordsnakes come into the ‘tricky’ and ‘fiendish’ categories and are a challenge even for adults. Why not try them out?

It can still rain in the summer term and these worksheets are also ideal for wet breaks and lunchtimes!

Resource of the Week: addtion, subtraction, multiplication and division

Most of our calculating worksheets are found in the respective year groups under ‘Calculations’, but I have provided a considerable number of extra pages in the ‘Four Rules’ section of the site which is often overlooked by our browsers.

This section covers both mental and written methods of addition, subtraction, multiplication and division and is steadily increasing over the weeks. With over 100 worksheets already, it covers skills from Year 1 right up to Year 6; from adding a single digit up to long division and there are some very clear descriptions about how to tackle these tasks.

Siome of the most tricky concepts, including the standard methods of multiplication and division can be practiced at length and there are clear set by step guides on how to do them.

Resource of the Week: decimal fractions

decimal-fractions-hundredths-y5

Some children have difficulty realising that the same numbers can be written in different ways, especially when dealing with decimals and decimal fractions. This page is a good test of understanding, probably most suited for year 5 children (/10 yrs old).

0.23 can be read as 23 hundredths or 2 tenths and 3 hundredths. As a fraction it would be written as 23/100.

With a number such as four and three hundredths it is important to keep the zero in the tenths so that it is written as 4.03.

Watch out for a common mistake on a question such as thirteen hundredths when children write 0.013; the one digit has been placed in the hundredths column when it should be in the tenths with the 3 digit in the hundredths.

Resource of the Week: subtraction across the thousands boundary

find-a-difference-by-counting-up-pg-1

This Year 4 maths worksheet can reveal a great deal about how children deal with numbers. It looks at finding differences crossing the thousands boundary.

Let’s look at 3005 – 8 which is easier to do mentally than on paper.

There are several ways that this can be done.

1. Count down, one at a time, 8 from 3005, saying each number as you go. Fingers may be held up on each count down until 8 is reached.

3004, (1), 3003 (2), 3002 (3), 3001 (4), 3000 (5), 2999 (6), 2998 (7), 2997 (8)

2. A different way is to take the 8 from 3000,  then add 5.

3000 – 8 = 2992

2992 + 5 = 2997

3. A third way is to take 5 off the 8 leaving 3.

Then take 3 off 3000 = 2997

It is well worth talking to children about how they do this kind of question and what strategies they employ. Much will depend on their knowledge of number.

If this question ia attempted using the standard written method for subtraction there are many children who will get confused with the adjustments that have to be made (crossing out tens and borrowing etc).

Resource of the week: change from ten pence

Using coins is a vital part of understanding number as it provides concrete examples of numbers in action. It is a really good idea to have a set of coins that can be counted out and swapped e.g. 5 one pence coins exchanged for a 5p piece etc. Why not set up a little shop at home and take turns buying and selling items? There is an amazing amount of maths involved in this, from learning how to write numbers to counting on and back and finding two or three lots of a number. If a shop is not available why not try this page?

Thanks to urbrainy.com for this money worksheet, suitable for year 1 children.

The worksheet asks for the change needed after spending various amounts. The easiest way to work out change is to start with the amount spent and count on up to 10. Eventually it is expected that children will know, off by heart’ the answers. In other words they will know, without counting that if you spend 6p you will have 4p change.

Resource of the Week: Year 6 Prime Factors

The term ‘prime factor’ is one which would make many adults shudder as they try to think back to their school days. In fact, it is a term that children would probably not met until secondary school, but is now firmly incorporated into the primary curriculum.

Here we have a maths worksheet for year 6 on how to find prime factors. Before attempting this page it is necessary for children to have a good understanding of what factors are and what prime numbers are.

One of the easiest ways of finding prime factors is to use a diagram, rather like a tree diagram with the numbers at the bottom all being the prime factors. Frequently the same number is found more than once. For example the prime factors of 36 are 3, 3, 2 and 2.

Starting with the number itself, find two numbers which multiply together to make that number. For example 36 can be made by multiplying 18 by 2. 18 and 2 are both factors of 36. Repeat this process until only prime numbers are left.

A good way of checking if all the factors have been found is to multiply them and the original number should result. e.g. 3 x 3 x 2 x 2 = 36

This page is found in our Year 6 calculating section .

Resource of the week: More than and less than signs

This week I am highlighting a worksheet on the ‘more than’ and ‘less than’ signs. Children from Year 3 onwards are now expected to recognise and understand these signs. This is very different from most adults experience, who would not have met these signs until much later. As the two signs are so similar this can be quite a tricky idea for children to remember. Hopefully, this page will help.

> means ‘is more than’

< means ‘is less than’

From year 1 children have been used to working with the terms ‘more than’ and ‘less than’ but this does not mean that they will understand and use the signs (especially as to many children it looks like the same sign flipped on its side). The way I remember it is that the arrow always points to the smaller number.

A key point in trying to become familiar with the signs is to read out loud number sentences so just as you can say that

3 +4 = 7 (three add four equals seven)

you can say that 3 + 4 > 6 (three add four is more than six).

This page can be found in our Year 3 Counting and Number category.
