1. Buckland CE Primary School
Parent Maths Workshop
Buckland CE Primary School

2. Aims of the Workshop
To outline the main changes to the new primary maths curriculum.
To provide parents with ideas and activities that they can use at home to support children’s maths development.
To outline the clear progression of the four calculation methods and how these are taught at Buckland.

3. Key Aims of the New Maths Curriculum
Fluent recall of mental maths facts e.g. times tables, number bonds. Etc.
To reason mathematically – children need to be able to explain the mathematical concepts with number sense; they must explain how they got the answer and why they are correct.
Problem solving – applying their skills to real-life contexts.

4. Key Differences of the new maths Curriculum:
Five-year-olds are expected to learn to count up to 100 (compared to 20 under the current curriculum) and learn number bonds to 20 (currently up to 10).
Simple fractions (1/4 and 1/2) are taught from KS1, and by the end of primary school, children should be able to convert decimal fractions to simple fractions (e.g = 3/8).
By the age of nine, children are expected to know times tables up to 12×12 (currently 10×10 by the end of primary school).

5. Good practice in Maths today!
Mental calculation skills are vital.
Children need the ability to estimate.
e.g. If I have 18 sweets in one bag and 33 sweets in another bag, how many do I have altogether.
Children can estimate by adding 20 and 30 and know that roughly the answer should be around 50.
Two points are clear about what mathematical skills children need in life. Educationalists say that children today need to learn 2 key skills. The ability to calculate mentally and the ability to estimate.
Mental calculation skills are vital. Just have a think how often you use mental maths in your own lives.
Shopping- working out change. Working out how many packets of biscuits or crisps you need to buy for a children’s birthday party.
Working out how long it is before you need to leave to pick up children from school.
Working out how many days left to do all your Christmas shopping?
A lot of maths in life is done in your head.
But within that I hope that you’re also estimating. When working out how long you have until you need to come to school, you round to the nearest hour or half hour.
So in school, we encourage children to estimate. If they are faced with a problem. I have 18 sweets in 1 bag and 33 in another bag. How many in total? Children in maths lessons today would be encouraged to round to the nearest 10 in their head and work out 20 add 30 to approximate an answer.
Alongside the ability to estimate, Educationalists today also say that children need to develop other key skills in maths.
Childrern need to learn maths in a context. Therefore in school we aren’t just giving children lists of sums to complete. We are asking them to really think. Research shows that many children who can tell you what 7 x 7 = 49 cannot answer a question in a real life context. E.g. There are 7 fields, each has 7 sheep in them. How many sheep are there altoghether.
Children need to be able to explain. What they are doing.
You may well say well what about the written calculations. Well these are still taught, but there is a balance. At St Luke’s we certainly would expect children by the time they leave school to know, understand and use a written strategy for more complex maths calculations but emphasis early on is placed on mental calculations.
If we look at the next slide, this will hopefully illustrate the point in hand.

6. Good practice in mathematics
All children need to learn maths in a real life context.
As well as knowing 7x7=49. Children need to be able to do the following:
There are 7 fields, each field has 7 sheep in them. How many sheep are there in total?
Children need to be able to explain how they have calculated or solved a problem.
In the new curriculum, written calculations are taught at an earlier age. The mental methods are essential for supporting pupils understanding of these written calculations.

You may well say well what about the written calculations. Well these are still taught, but there is a balance.
Research shows that teaching children written procedures at too early a stage in their mathematical development can have an adverse effect upon their ability to operate mentally.
In line with many other countries, mental calculation skills are being taught and focussed upon, and the introduction of written methods are delayed until children are ready. At St Luke’s we certainly would expect children by the time they leave school to know, understand and use a written strategy for more complex maths calculations but emphasis early on is placed on mental calculations.
If we look at the next slide, this will hopefully illustrate the point in hand.

7. Good practice in mathematics
Connections are made between mathematics topic areas, other subjects and between objectives.
Children are taught to reason mathematically so that they able to consider if their answers are plausible.
Children are taught to consider the most effective calculation method and approach to calcualtions.

8. How do children learn the calculation methods?
Counting of objects and mental counting.
Early stages of calculation with learning of addition and subtraction number facts, with recording.
5 + 8 = or =
Work with structured number lines
Work with larger numbers, unstructured number lines and informal jottings e.g
So where do we start in maths.
The first thing we do is to teach children to count. They count real things. The count forwards and backwards. They counting in ones, twos, fives and then tens. In this way, children are really gaining a sense of number.
They then move on to learn number facts.
Then we would ask children to learn number facts. By that I mean children would get to know pairs of numbers that make =10, 7+3 = =7.
Structured number lines already have the numbers on them.
Unstructured number lines are blank and children fill in numbers. +3
+20 47 50 70 73 73

9. I must remember to add the least significant digit first
Informal written methods, first with whole numbers and decimals.
Formal written methods.
With any calculation, teach children to consider first whether a mental method is appropriate and remembering to estimate first.
Remember to partition
I must remember to add the least significant digit first =
= = 123
(8+3)
(60+90)
( )
Partitioning is a key tool that all children are encouraged to use whether adding, subtracting, multiplying or dividing.
When children are ready, they move to using informal written methods- horizontal first and then in the vertical layout.
If and when they are ready, they can move to the more formal compact written method.
In terms of the numbers that your child uses within this process, refer to year group objectives to find the sort of numbers for each year group.

10. 100 20 3 100 20 3 Addition = + + Practical addition of real objects.
Use of a structured number line to add.
Partitioning to add.
100 20 3 =
100 + 20 + 3

11. Addition Continued… 4. Use of an unstructured number line. 37 + 48= 4878 68 80 58
+10 +5 +2 85

12. Addition Continued…
5. Expanded horizontal method, leading to columnar addition:
Adding the least significant digit first. =
Estimate: is nearly so estimate answer should be near 360.
Illustration of how to use Dienes equipment to ensure children have an understanding of place value when using columnar addition.
Empty number lines will still be used at this stage to support.
       
        

13. Addition Continued…
6. Columnar addition (formal written method): When children are confident working with larger numbers using the previous strategies, they will be introduced to ‘carrying’ digits Estimate: =4000 Answer should be less as I have rounded up.
Children will eventually move on to adding larger numbers as well as decimal numbers and adding more than 2 numbers at a time.

14. Subtraction Subtraction as taking away from a group:
Subtracting by counting back and on: children begin to use numbered lines to support their own calculations, initially counting back in ones before beginning to work more efficiently.
Finding the difference by
either counting on or back.

15. Subtraction Continued…
4. Subtracting TU – U and TU – TU: use of an unstructured number line.
Use empty number lines to find the difference by bridging through multiples of ten.
Subtract by starting with the first number and partitioning the second, i.e.
74 – 20 = 54
54 – 4 = 50
50 – 3 = 47

16. Subtraction Continued…
5. First stage of column method, including expanded method:
•Written recording should follow teacher modelling around the size of numbers and place value using a variety of concrete materials, e.g. straws, Numicon, Dienes and place-value cards.

17. Subtraction Continued…
6. Second stage of column method: the concept of exchange is introduced through continued use of practical equipment (manipulatives).
Children will eventually move on to subtracting larger numbers as well as decimal numbers.

18. Multiplication
Developing early conceptual understanding of multiplication: practical multiplication - 2 x lots of 4.
2. Understanding multiplication as repeated addition: use of arrays and number lines x 5 or
Number lines:
6 X 4 = 24
So: ‘Six taken four times”

19. Multiplication continued…
3. Relate multiplying a 2-digit by 1-digit number using repeated addition and arrays to represent
4. Relate multiplying a 3/2-digit by 1-digit number with arrays towards using long/short multiplication

20. Multiplication continued…
5. Relate multiplying a 4/3/2-digit by 1/2-digit number with grid to using long multiplication.
6. Relate multiplying a 4/3/2-digit by 1/2-digit number with grid to using short multiplication.
Children will eventually move on to multiplying larger numbers as well as decimal numbers.

21. Division
Sharing or Grouping – Division is initially represented pictorially.
6 sweets shared between 2 people. How many each?
There are 6 people in a room. Put them into groups of 2. How many groups can you make?
2. Using a number line and arrays to show division.
6 ÷2 = 3
Sharing and grouping are two totally different concepts that children need to understand.

22. Division continued…
3. Dividing a 2-digit by 1-digit number, representing this efficiently on a number line.
4. Dividing a 3/2-digit by 1-digit number, representing this efficiently on a number line, also in relation to long division

23. Division continued…
5. Dividing a 4/3/2-digit by 1-digit number, in relation to long division.

24. Division continued…
6. Dividing a 4/3/2-digit by 2/1-digit number, in relation to long and then short division
