## How Numeracy Is Taught at My Son's School

I'd always been intrigued and puzzled by how maths and numeracy is taught at schools. Fortunately my son's primary school has an enlightened policy of explaining to parents the various techniques that they use. I had the opportunity to be shown the methods and the school also issued a small booklet that explained the approach step by step.

I found this information fascinating, useful and a bit of an eye-opener. I thought I would share it and see how my son's school's methods compare to other UK schools and to schools across the world.

## Primary School National Maths Strategy/Curriculum

The way maths and numeracy is taught at school seems to continually discussed and revised. Just this month (June 2012), Michael Gove (Secretary of State for Education) unveiled proposals to overhaul the maths/numeracy curriculum. It is proposed that there will be more emphasis on learning specific key tasks. For example 11 year olds will be expected to learn up to their 12 times table (currently the target is up to the 10 times table).

Secretaries of State will come and go, but children will always have to learn how to add, subtract, multiply and divide. This article will focus on how this basic numeracy is taught at my son's school. There is much debate about whether children should learn by rote (for example by chanting their times tables) or by developing a deeper understanding of how numbers work. I'm pleased to say that my son's school use a wide spectrum of strategies to enable all children to achieve success.

## My Son's Primary School's Numeracy Strategy

This is an overview taken from a handout:-

"Addition and subtraction, and multiplication and division, are taught alongside each other so that the children can see the relationship between them, recognising that multiplication can be repeated addition and division can be repeated subtraction. Children are also encouraged to understand the importance of estimation and other checking including using inverse operations.

A variety of recording and calculation methods are taught as a progression. However, teachers are flexible in their approach and will realise that some children are ready to progress to the next step and some children will need consolidation on the previous step. This is addressed through appropriately differentiated teaching. It is also important to understand that not all children will reach the final stage in each progression but they will be able to perform a calculation successfully."

So that's the official line. It might be good mathematical practice but it's not plain English! To be fair to the school they also provided examples of how addition, subtraction, multiplication and division is actually taught. I'll set out the approach in detail.

## How Addition is Taught at Primary School

This is the progression (starting with the easiest methods) that my son's school follows for addition:

** Counting On** - Just counting- 11 + 5 = 11, 12, 13, 14, 15, 16. I guess using fingers, or for larger numbers, number lines or squares.

** Using a Known Fact** - Just learning simple additions. E.g. 3 + 2 = 5.

** Number Bonds** - Learn which pairs of numbers add up to 10 and 20.

**Using a Derived Fact** - This builds on a known fact or number bond. For example 15 + 5 = 20, therefore 16 + 5 = 21.

** Hundred Squares** - A lot easier to understand this with actual examples- check this link, add using a hundred square

** Adding Several Numbers** - Look for pairs of numbers that add up to 10 and add these first. Children are also taught to start with the largest number. Also children look for pairs that make 9 or 11 and add these by adding 10 and then adjusting by 1.

** Partitioning and Recombing** Best explained with an example:

85 + 16 = 85 + 15 + 1 = 100 + 1 = 101

** Partioning in Tens and Units** - Adding the tens up first, followed by the units. For example:-

82 + 25 = (80 + 20) + (2 + 5) = 100 + 7 = 107

*I can see how all the previous steps build to this point which in turn leads to the final traditional "Standard Written Method with Exchanging"- see the last step below. There are couple of points that strike me. Firstly it must be painful for bright children to go through all these steps- especially if they have been taught the fundamentals at home. I hope that schools have strategies to avoid such frustration. Secondly it's impossible, when you know how to add up, to fully appreciate the benefit of this step by step approach. Your natural inclination is to be impatient and say why not just teach the final method. I now understand how these steps should allow children of all abilities to build their numeracy skills in a relatively consistent and reliable manner.*

**Counting on in Multiples of 100, 10 or 1** Here's and example:

86 + 57 = 86 + 50 + 7

86 + 50 = 136 + 4 = 140 + 3 = 143

** Adding Significant Digits First** An extension of partitioning. Add hundreds, then tens and then units. Children are expected to do these sums in their heads, perhaps with jotted notes to help them

Example:

625+ 48 =

600

60

13

= 673

__Adding Near Multiples of 10__

Example 527 + 298 = (527 + 300) - 2 = 827 - 2 = 825

**Compensation** Small extension of previous step

527 + 83 = (527 + 100) -17 = 627 - 17 = 610

__Standard Written Methods with Exchanging__

This is the method I remember from school. Adding the units first and carrying below the line, as per this example:-

Excellent hub. My tutor when I was little taught me some of these techniques. Interestingly enough when the new math came into vogue during the 70's they were thrown out the window. The real key is helping kids to enjoy playing with numbers instead of being afraid of math.

Nursery rhymes are a good start. One two buckle my shoe....

There are a couple of points I find very interesting from your post. I have recently graduated as a Maths teacher in Northern Ireland, which follows a different curriculum to the rest of the UK.

1) "recognising that multiplication can be repeated addition and division can be repeated subtraction."

This is something which we were always told to avoid teaching as it was viewed to be the incorrect way of teaching the concepts of multiplication and subtraction. Is there any more information on this?

2) "Your natural inclination is to be impatient and say why not just teach the final method. I now understand how these steps should allow children of all abilities to build their numeracy skills in a relatively consistent and reliable manner."

A great point. Obviously your son's school policy of showing the parents in such detail how the topics are taught has been very successful in your case. Perhaps something more schools should follow. In our training college there was a debate about whether children should be taught the core concepts (how to add) and derive the rules (the methods you described) from these, or whether they should be taught the rules and use these to build to the core concepts. I would usually fall upon the side of the former argument, but your post has provided an excellent insight into reasoning behind the latter.
