Free Y3 maths worksheet: properties of quadrilaterals

Wednesday, November 19th, 2008

Free maths worksheet from mathsblog.co.uk: properties of quadrilaterals.

The term quadrilateral is often  misunderstood and confused with the term rectangle. A quadrilateral is any flat shape which has four straight sides. The angles do not have to be right angles. Rectangles and squares are special cases of quadrilateral.

Look out for quadrilaterals all around you in the real world.

Free Y3 maths worksheet: counting on (teens)

Monday, November 17th, 2008

Free maths worksheet from mathsblog.co.uk

Counting on is a very powerful tool when using mental methods of calculating. This worksheet concentrates on counting on a teen number to a number in the hundreds and can be seen as an addition problem (143 + 16).

The usual method of doing this requires the ability to partition (ie know that 16 is 10 + 6) and is in two parts:

1. Count on ten from 143 making 153.

2. Count on 6 from 153 to make 159.

There should not be a need to do this type of question on paper.

Free Y3 maths Worksheet: Make 1000

Tuesday, September 9th, 2008

Free maths worksheet from mathsblog.co.uk

1000 is a very large number for children working in Year 3 and one which is difficult to imagine the size of. The sheet asks how many different ways can two numbers be added to make 1000, using only whole hundreds.To be able to do this children need to be confident with their numbers up to 10 and be able to know which pairs of numbers add up to 10.

As an investigation it is very similar to asking how many ways can 100 be made only using whole tens.

shape imageA thousand is a pretty big number to work with and one of the best ways to beginn to appreciate its size is to work with whole hundreds to make 1000.

To be able to do this it is essential to know pairs of numbers which make 10. If these are not known by year 3 then it is essential that they are as soon as possible.

Free Y3 maths worksheet: Making 100 by adding

Wednesday, July 2nd, 2008

shapeHere is a straightforward worksheet which is more open ended. It allows the child to find two numbers which add up to 100. Some children will work in a well ordered methodical way eg by adding whole tens 90 + 10, 80 + 20, 70 + 30 etc whilst others will choose a more random approach.

Watch out for incorrect sums that add up to 110 eg 45 + 65.

Free Y3 maths worksheet: make shapes and describe their features

Wednesday, May 21st, 2008

shapeIt’s a while since I sent anything up for children in year 3 and for shape so here is a worksheet just for them!

The best way to go about this is to have some plastic or card shapes: rectangles and right angled triangles. If not, the worksheet can be printed out on to card and the shapes cut out.

It is quite possible to make all the polygons mentioned on the worksheet, and in fact an extension activity could be to make a shape with the most possible number of sides.

it is important to let children experiment with shape whilst using the correct language. Don’t be afraid to call a six sided shape a hexagon and remember that the sides do not all have to be the same length - this only applies to a regular hexagon.

Free Y3 maths worksheet: Measuring in kilometres

Wednesday, April 16th, 2008

shape imageChildren in the UK get far less experience at using kilometres than most Euoropeans because we have decided to keep with the mile for most of our longer measuring. Of course this is a nonsense: to start with a system using mm, cm and metres and then switch to a completely different system ie miles does not make any sense at all! Until our road signs are changed there is little hope of any improvement in this situation.

Whilst there are 1760 yards in a mile the much simpler metric system has the easy to calculate 1000 metres in a kilometre.

At this stage children should be beginning to write half a kilometre as 0.5 km but 1/2 km is acceptable. This free maths worksheet concentrates on writing half kilometres as decimal fractions.

countingA second, quick revision of counting on. Whilst some children may well still be starting with the given number and then counting on with their fingers others will be using more sophisticated methods such as:

to count on 9, add 10 and subtract 1

to count on 11, add 10 and add 1

to count on 8, add 10 and subtract 2

to count on 12, add 10 and add 2

shape imageHere’s a very straight forward little revision for children to practise their counting on in the hundreds. In Year 3 many children will still be using their fingers to count on whilst others will be learning to add the number using the facts they already know. As most of these questions cross the next tens boundary this is not so easy.

shape imageGetting to know pairs of numbers which total 100 is quite tricky and often will be ‘worked out’ from other knowledge. However, some certainly can be learnt, including these pairs which all have 5 as the units.

Watch out for a common mistake when doing this. Many children will make the answer 10 too many, for example saying that 65 needs to be added to 45 to make 100.

Again, if the answers are not known the easiest way to work them out is to count on.
