Year 2 maths worksheet: counting on in tens

Here we have another page to help with counting on in tens from a 2-digit numbers. A little care needs to be taken with these as the question asks,

“How many tens did you count?”

So, when counting in tens from 23 to 43 the answer is 2 (tens), not twenty.

Many children (and adults) count out loud and use their fingers to work out the answer to this type of question, holding out one finger each time ten more is added. Nothing wrong with this but care needs to be taken that ten is not counted when saying the first number out loud.

Year 4 maths worksheet: Multiply multiples of 10

This page is an excellent illustration of how knowing ‘tables’ and understanding place value can make other maths much simpler. These questions are all multiplying multiples of ten by a single digit.

If you know that 7 x 8 = 56 then 70 x 8 can be done ‘in your head’ very quickly.

probably the hardest questions on this sheet are those set out like this:

490 x 7 = ??

The best way to approach this is to ask what times 7 makes 49? and work from there.

Coming soon: Multiplication, counting and converting units

Next week we have an excellent illustration of how knowing ‘tables’ and understanding place value can make other maths much simpler with a page of  questions all about multiplying multiples of ten by a single digit.

If you know that 7 x 8 = 56 then 70 x 8 can be done ‘in your head’ very quickly.

Many children (and adults) count out loud and use their fingers when counting on in tens, holding out one finger each time ten more is added. Nothing wrong with this but care needs to be taken that ten is not counted when saying the first number out loud.

It is a sad state of affairs that schools are still having to teach children to convert imperial to metric units, even when we have been metric for over 40 years. nevertheless I have included some work on concerting imperial and metric units.

Year 6 worksheet: Add decimals mentally

A straightforward mental arithmetic page on adding decimals. The process is very much the same as adding two 2-digit whole numbers. When adding in our heads we usually start with the largest numbers, which, of course, is the opposite of the way we do it on paper. This needs pointing out to children as many, even in Year 6, lack the strategies necessary for mental addition.

When adding 3 decimals there are several different strategies that can be used, including:

looking for pairs that make 1

starting with the largest number

counting on

knowing doubles etc.

iPhone app: multiplication game

It’s a first for me: an iPhone App. But, it is a good one if you’ve only got a few pence to spare and you will need to be pretty nifty with your tables to get a good score. Practice your tables and see those cows move faster and faster with this great app. It’s easy to begin with, but don’t be fooled!!

  • Practice any table from 1 to 12
  • Challenge yourself to see how many correct answers you can get
  • See if you can beat your highscore!

The app is available in the app store now.


Calculator game: Multiples of 10

multiples of 10_larger numbersMultiples of ten are fairly easy to work out, but nevertheless this is a good game of strategy to play to help reinforce multiples of 10. Choose a number on the grid then try and make it on the calculator by multiplying a number by 10. If correct and the answer on the calculator matches the number on the grid place a coloured counter on the grid. Play then goes to your opponent, with the aim of trying to get 4 in a row.

Year 3 maths worksheet: Reading scales

Children are used to reading scales where the divisions go up in ones, but they find it much harder when either they go up in larger numbers or when not all the divisions are numbered. This worksheet does both of these. The ruler shown is a scale drawing and each division is 10 cm, but only the 100 cm division lines are named.

Once it has been established that each mark represents 10 cm., it is relatively straightforward to work out the lengths shown. As children usually only use centimetre rulers this might be the first time they come across a ruler where not all the divisions are numbered.

Coming soon: measuring, decimals and multiples

Children are used to reading scales where the divisions go up in ones, but they find it much harder when either they go up in larger numbers or when not all the divisions are numbered. Next week we are publishing a measuring worksheet which does both of these. The ruler shown is a scale drawing and each division is 10 cm, but only the 100 cm division lines are named.

Multiples of ten are fairly easy to work out, but nevertheless practice makes perfect and coming up soon  is a great game of strategy to play to help reinforce multiples of 10.

We will also be sending up a straightforward mental arithmetic page on adding decimals for Year 6. The process is very much the same as adding two 2-digit whole numbers. When adding in our heads we usually start with the largest numbers, which, of course, is the opposite of the way we do it on paper. This needs pointing out to children as many, even in Year 6, lack the strategies necessary for mental addition.

Year 6 investigation: World Cup Final

With the World Cup Final rapidly approaching and SATs out of the way, what better way to spend a maths lesson than looking at the possibility of England meeting Brazil in the final?

With a predicted score of 5 all, after extra time, the task is to try and work out how many possible different scores there could have been during the game.

Of course there are lots of possibilities but to start with the score must have been 0 – 0. Then England could have scored to make it 1 – 0 or Brazil could have scored to make it 0 – 1.

As it is such a big task it would be a good idea to break it down into smaller tasks eg firstly work out all the possible scores up to a score of 1 – 1. Then work out all the possible scores up to 2 – 2. and so on. Done in this way there are plenty of opportunities to spot patterns, including square numbers.

Extension could go to even higher scores!

Resource of the Week: Written addition of money

standard-money-addition-p1

Once children are familiar with the standard method of addition for 3 digits they can be introduced to addition of decimals. One of the best ways to do this is by adding money.  On this page the first eight questions have been written out in the correct way, but the next seven will also need to be written out using the same method. The key here is to keep the decimal point in line as the numbers in later addition of decimals may not necessarily all have two digits after the decimal point. Also, don’t forget the £ sign in the answer.

This page and other similar pages can be found in our Four Rules Maths Worksheets.
