Maths worksheet: 2 times table

2x table maths worksheets from mathsblog.co.uk

The 2 times table is usually the first that is learnt by children, usually after a lot of practice with doubling small numbers. There is a danger when only using the two times table that children think of multiplying only as ‘timesing by 2’ or doubling.
Another danger is that some children are taught that they only need to count up the answers: 2, 4, 6, 8 etc. However, this is not very helpful if a child needs to know what 2 x 9 is; they do not want to have to go through the whole counting up in twos 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: Continue reading “Maths worksheet: 2 times table”

Free Y4 maths worksheet: number grid in tens

In order for children to be really confident with handling numbers it is very important that they have a great deal of practice in counting forwards and backwards.

To re-inforce place value counting on and back in ones, tens, hundreds and thousands is especially worthwhile.

This might appear to be easay, but problems do arrive when crossing the next hundred or thousand. A number line or grid is very useful in helping with this.

Free maths worksheet: counting and matching

Free maths worksheet from urbrainy.com

Thanks to URBrainy.com for this worksheet. They specialise in early years maths and have some great free resources. This is a counting and matching page. Matching equal numbers of things is an important step for young children and one which should be encouraged as often as possible. Worksheets are only one way of doing this; there are plenty of opportunities in the home for matching eg laying the table with knives and forks, spoons with bowls etc.

World Maths Day

World Maths Day 2009 info from mathsblog.co.uk
worldmathsdayWorld Maths Day was a huge success last year, with over one million students from over 150 countries taking part. Altogether 182 455 169 questions were correctly answered. Wow!
Whingate Primary School was the top UK school with 170 139 correct answers. Well done to them! You only need to see how their maths SAT scores have risen over the past few years to know what an effect this event can have!
There is nothing else in the world quite like this and it can act as a great stimulus for children to improve their mental arithmetic. The students play against each other at mental arithmetic games in real-time across the globe. Each correct answer gains one point.
Next year’s event will take place on Wednesday, 4th March 2009 and schools will be able to register in February 2009. This might seem a long time away but if schools are going to enter it might well be worth thinking about it now, make sure the date is kept free and start practising that mental arithmetic!
If you are a parent with a child who loves quick responses to mental arithmetic why not go to your school and suggest they enter? It costs nothing!

Multiplying 2-digits by 2: moving towards standard written methods

Free maths worksheet from mathsblog.co.uk

Here is a worksheet which looks at multiplying a 2-digit number by 2. It uses a method taught in school prior to children using the standard written method, with which you are probably familiar.

This method of multiplication encourages understanding of the process of multiplying a 2-digit number by  a 1-digit number. The questions on this page would not normally be completed using written methods: mental methods should suffice. It would be expected that children could do these ‘in their heads’ from a  knowledge of doubling. However, carrying out the calculation with numbers that they are familiar with should help with understanding the method.

U R Brainy launches full maths worksheets site

After a couple of months in beta mode urbrainy.com has fully launched today. Aimed at parents of children in their early years it provides a whole host of colourful maths worksheets. Plenty are free but if you want the full 1000 + then there is a subscription of £10.00 for a year – pretty good value, I think, and the site is nice and bright.

They have let me publish some of these maths worksheets recently and I will hope to do so again in the future. Here is a typical sample of four pages about ordering numbers.

News: The Story of Maths BBC 4

If you are interested in how mathematics has come about and all the wonderful developments in science that have come from maths, then this is the series for you.

Starting on Monday 6th October at 9.00pm on BBC 4 it takes a journey through the past and around the world, to Egypt, China, India, Russia, The Middle East and more.

It shows how maths was crucial to the success of all the great civilisations. After all, without maths there would be no time keeping, no money, no cars, no planes, no electricity and indeed you would not be able to read this on a computer screen.

It brings us right up to today, with examples such as prime numbers, knowledge of which until recently was of little practical use, but now nearly all our security pin numbers etc are based on prime numbers.

Marcus du Sautoy, Professor of Mathematics at the University of Oxford leads us on our journey and there are a number of supporting interactive games etc at Open2.net to go with the series.

2-digit addition: moving towards standard written methods

Addition worksheet from mathsblog.co.uk

Many parents say that the methods used today for adding are not the same as when they were at school. Often this is not strictly true: the final standard written method is the same, but the steps used to reach this standard method have changed. The worksheet attached explains this in more detail.

The method of addition encourages understanding of the process of adding two, 2-digit numbers. It is known as ‘adding the least significant digit first’.

The method is to add the units first, then add the tens, finally adding the two together. It is a ‘half-way house’towards the standard written method, explaining what happens when the tens boundary is crossed during adding the units (ie when the units add up to more than 10). At this stage ‘carrying’ does not need to take place.

Free Y2 maths worksheet: make 5 sided shapes

Free maths worksheet from mathsblog.co.uk

A pinboard and some elastic bands are a great resource for young children to use when exploring the properties of shapes.

A reminder that this can be made by nailing panel pins or small nails into a piece of plywood approximately 24cm × 24cm.

Cut out the plywood and mark a grid of lines at 2cm intervals in both directions across the plywood. Tap in the pins at the points where the lines of the grid meet. Leave enough of the pins protruding to accommodate elastic bands.

5 sided shapes are not that easy to draw or make as they can not be made using just right angles. This is a good exploration of the different types of shape that can be made and whether shapes are the same or not if they are rotated.
