Aims- Enable you to understand the changes occurring in
mathematics due to the new curriculum- Provide you with a greater understanding of how
mathematics is taught in school and progression of the 4 operation methods through Key Stage 2.
- Enable you to see the types of different questions children are asked in their assessments including Year 6 SATS and Level 6.
- See the importance of mental mathematical skills and the strategies children are taught.
- Help you understand how you can help your child at home.
The New Curriculum
- More cross curricular-Greater links with Computing-Problem Solving no longer taught discretely but embedded within each area/domain of mathematics-Divided into Lower Key Stage 2 and Upper Key Stage 2-The 2016 assessment tests will be based on the new curriculum content
The New CurriculumHow we are implementing the new curriculum
-Years 3-5 are following the new curriculum-Year 6 are following the objectives from the old curriculum -All year groups are including more work on computers and ipads to support and consolidate learning-In each year group the expectations are higher
The New CurriculumNew ExpectationsBy the end of year 4 pupils should-memorise their multiplication tables up to and including the 12 times table-show precision and fluency in their work
By the end of year 6 pupils should - Be fluent in written methods for all four operations, including long multiplication and division, and in working with fractions, decimals and percentages. -Pupils should read, spell and pronounce mathematical vocabulary correctly.
Why so many methods?
- Children are entitled to be taught and to acquire secure mental methods and efficient written methods of calculation for each operation which they know they can rely on when mental methods are not appropriate. We teach them a range so they can choose the one they prefer and proves most accurate for them.
The 4 operations
The Four OperationsAddition – Lower KS2
Partitioning:Partitioning means splitting the number into the tens and units.
48 + 36 = 40 + 30 = 70 40 + 8 8 + 6 = 14 30 + 6
= 84 70 + 14 = 84
The Four OperationsAddition – Lower KS2
Expanded methods in columns:
Children’s understanding of place value has to be secure. 48 + 36 = 84
4 83 6 +1 4 – adding units first7 0 – adding tens8 4
The Four OperationsAddition – Upper KS2
Column Method:
This method remains efficient when adding larger numbers and decimals. It is a quick and reliable method. 48 + 36 = 84
4 83 6 +8 4

The Four OperationsAddition – Upper KS2
- Column MethodThis method remains efficient when adding larger numbers and decimals. It is a quick and reliable method. 379 + 92 = 471

Counting On ‘Finding the difference’
-Count on from the smallest to the largest once again bridging through ten or a multiple of ten.

The Four OperationsDivision – Lower KS2
Grouping using multiplication knowledge:
This method uses children’s understanding on times tables and links to their mental calculations.
e.g. 43 ÷ 7 =
I know 6 X 7 = 42 so …
43 ÷ 7 = 6 remainder 1
The Four OperationsDivision – Lower KS2
Grouping using jottings This enables the introduction of remainders

Children building up confidence, using their multiplication knowledge, to subtract larger ‘chunks’.
The Four OperationsThis method is the next step after chunking. It is a more compact method.

Now it’s your turn!
Mental MathematicsIt is essential children have secure knowledge and recall of mental facts including:
-Place Value including decimals-Number bonds -Times tables from 0 to 12!-Corresponding division facts-Rounding to enable estimation of answers
Mental MathematicsMental Mathematic Strategies:
-Use number bonds to 10, 20 and 100 transferable to 1,000 and decimals-Multiplication and division by 10, 100, 1,000, 0.1-Use doubles and near doubles-Partition into thousands, hundreds, tens and units-Adding near multiples of 10. Adding the multiple then add or subtract 1-Subtracting near multiples of 10. Subtracting the multiple then subtracting or adding 1. -These are transferable to multiples of 100, 1,000 etc.
