The Importance Of Times Tables

October 15, 2015 § Leave a comment

As much as children may hate them, times tables are one of the key foundation stones of good maths ability. Even when you get to GCSE level, knowledge of times tables is very important: it helps with factors and multiples, it makes long multiplication and long division considerably quicker and easier and times tables will crop up in practically every maths topic in one way or another.

For many children, learning times tables is hard and can be frustrating. But learning them is simply a case of practice makes perfect; the more you do them, the easier it will be to remember them!

But, it’s not just a case of learning the times tables in order. A large number of children will be able to learn their times tables when they are saying them all in the correct order, but will they be able to answer 6 x 5 without having to go through 5, 10, 15, 20, 25, 30? Being able to recall the times tables facts without having to think too much about it will be a great advantage for future maths work, so it’s worth putting in the effort to learn them that way.

Here’s something to try:
As an example, say that your child needs to know their 4 times tables. Start by making sure they can say them in order quickly and without having to think about it. To get to that stage, each day get them to say them all the way through, perhaps when they are having breakfast or before bedtime. Once they have mastered that, start calling out random 4 times tables questions for them to answer. Do 2 or 3 at a time and, for each one they get right, give them a star. Rewards make times tables considerably less tedious!

A Quarter of a Teaspoon

November 3, 2014 § Leave a comment

I was measuring out spices for a curry mix at the weekend and it asked for a quarter of a teaspoon of turmeric. I opened up the cutlery drawer and pulled out 4 different teaspoons . . . and they were all different sizes! Did I want a quarter of my biggest teaspoon or my smallest one . . . or one in between?! And how an earth am I supposed to work out a quarter of it?!

It can all make for a pretty dicey cooking experience! Not to mention the advice that we have had in recent years not to use a teaspoon from the cutlery drawer when measuring out medicines for children.

So, what exactly is a teaspoon supposed to be? In fluid measures, it should be 5 millilitres. And in dry measures, it’s about 8-10 grams, but that depends on what you are measuring. And, of course, those sizes are for a LEVEL teaspoon – don’t forget that you can also get rounded teaspoons and heaped ones too!

The only way you are ever going to be exact is by getting a special set of measuring spoons. As it goes, for cooking I just pick a teaspoon, stick in what I think is about right and hope for the best!

The Wonderful World of Chocolate and Maths!

October 14, 2014 § Leave a comment

It’s chocolate week this week – a time when you actually have an excuse for indulging!

And at the same time, Ireland are enjoying maths week . . . maybe a less pleasurable experience for most people!

So, let’s mix it together and take a look at the importance of maths in chocolate.

HappyChocolateSumWe are all used to seeing the percentages on the front of more high-end chocolate bars, saying for example “70% cocoa”. But what does that actually mean?

The percentages on the front of chocolate bars refer to weight: they refer to how much of the total weight of the chocolate bar is made up of actual cocoa bean products. By cocoa bean products, we mean cocoa butter and cocoa solids. So, “70% cocoa” means that 70% of the weight of the chocolate bar is made up of cocoa bean products, while the rest is mostly sugar (yikes!) with a touch of vanilla, lecithin (this makes it smooth and creamy) and milk solids if it’s milk chocolate or white chocolate.

A typical cocoa bean is made up of 54 percent cocoa butter and 46 percent cocoa solids (the solids are often ground down and used to make cocoa powder). Different amounts of the cocoa butter and cocoa solids will be used depending on what type of chocolate you eat. White chocolate, for instance, contains cocoa butter without the cocoa solids.

So, as you sit back and tuck in to a chocolate-y treat, spare a thought for those clever chocolatiers who have mixed the right percentages together to make it!

New National Curriculum for Maths

September 21, 2014 § Leave a comment

The new curriculum came into force this month for everyone except Years 2 and 6. Although it may seem a little daunting, the new maths curriculum is nothing to be afraid of! It seems much harder than the previous curriculum, but in reality, they are just learning topics at a slightly earlier age so that they can build on that knowledge for a longer period of time. In maths, some topics have actually been removed from the Key Stage 2 curriculum, such as probability.

By starting the teaching earlier, the theory is that they can then go into much more detail and ensure that children are able to get to the stage where they understand the methods and can solve problems rather than just perform calculations.

Take a look at our Year 1 Maths page to see the topics Year 1 students will be covering. And don’t forget to try our brand new Year 1 Fractions test!

Our Homage to Cycling Statistics!

August 17, 2014 § Leave a comment

We love statistics! Yes, we may say we hate maths, but as a nation we seem to get great pleasure from crunching those numbers and finding out what percentage of people do what, when and where.

So, as very proud sponsors of TNT BMX Club, we thought we would celebrate their first club race today with a few cycling statistics.

The Department for Transport releases walking and cycling statistics each year and this year they released the data from 2012/13:

AreaChartWell done to Cambridge and Oxford! See . . . clever people like to cycle!

AgeChartCome on girls! We need to get cycling! I know 2 people who completed the Prudential 100 last week – one was a 30-year old woman and the other was a 72-year old man, so well done to minority cyclists!

But whatever the statistics say, ENJOY YOUR CYCLING! And good luck to everyone taking part in the TNT BMX races this week!

The Murky World of BODMAS!

August 3, 2014 § Leave a comment

Recently a parent asked me about a question they had come across in one of their 11 Plus practice papers. Their child had put E as the answer and his Mum was sure this was correct, but the answer book said it should have been A.

The answer came down to BODMAS (or BIDMAS). It’s one of those awkward little things that no one ever remembers! But, it’s something that rears its head in 11 Plus, SATs and GCSE exams.
BODMAS is basically the order in which we complete a complex sum. It stands for:

Orders (or Indices)

It reminds us that when dealing with a sum, we have to do whatever is in the brackets first, then deal with any indices (e.g. square numbers or cube numbers), then we can do divisions and multiplications, then finally additions and subtractions.

We must be careful, though, because all is not as it seems when it comes to BODMAS!

Although Addition comes before Subtraction, this does not mean that all the additions have to be done before the subtractions. For instance, 6 – 3 + 1 is done from left to right, so the answer is 4. If you were to do the adding first, you would get an answer of 2, but this is not correct. So, really, BODMAS should be read as:

Brackets first
Orders or Indices next
Then any Divisions and Multiplications in order from left to right
Then any Additions and Subtractions in order from left to right

Basically, BODMAS sounds better than BOMDSA! It’s just a reminder to do your multiplications and divisions before moving on to your additions and subtractions.

So, that brings us to the question the parent raised. The question was:

Which of the following gives the same answer as 6 x 2 + 12?
A. 48 – 8 x 3     B. 3 + 11 x 2     C. 3 x 7     D. 24 ÷ 2 – 1     E. 2 + 4 x 4

Using the rules of BODMAS, 6 x 2 + 12 = 12 + 12 = 24
A. 48 – 8 x 3 = 48 – 24 = 24
B. 3 + 11 x 2 = 3 + 22 = 25
C. 3 x 7 = 21
D. 24 ÷ 2 – 1 = 12 – 1 = 11
E. 2 + 4 x 4 = 2 + 16 = 18

And that is why the answer is A, not E!

Summer Holidays and 11 Plus Revision

July 11, 2014 § Leave a comment

Your 10 year old thinks: “Yay, 6 weeks off school!”

You think: “Oh no, 6 weeks without school – what if they forget everything?!”

It’s that time of year again when parents and children are working hard towards their 11+ exams . . . and many students have to sit the exam almost immediately after a long holiday from school.

The 11 plus is, of course, a very important exam. But, we mustn’t forget that they are only 10 year olds and they have been working hard at school all year. Relaxation time is vital, otherwise they will suffer “burn out” before they get to the test. So here is a handy 11 plus revision timetable for the summer to make it an efficient and enjoyable (or as enjoyable as schoolwork can be!) experience.

11 Plus Revision Timetable

Even if you are away on holiday, take some books away with you. Your child will feel more relaxed on holiday, so may be more inclined to do some work.

The timetable is just a guideline, each child is different. 11+ revision should be varied with each child’s personality and work ethic. Try our 11+ revision worksheets to help in preparing your child. But most of all, enjoy your summer holidays!
