What is the National Curriculum anyway? A new version was introduced in September 2014. Academies, free schools and independent schools do not have to follow the curriculum.
2
Why the changes? “[The new curriculum] combines the best elements of what is taught in the world's most successful school systems, including Hong Kong, Massachusetts, Singapore and Finland, with some of the most impressive [existing] practice from schools in England."
3
The idea - somewhat controversially - is for children to "go further...at an earlier age"
4
So what's all this about fractions at five then? This is about very simple fraction work initially, such as understanding what a half or a quarter of a cake or biscuit is. Oh and calculators will not be allowed until secondary school!
5
pupils being expected to be taught times tables to 12 by age 9 and converting fractions to decimals in year 4.
6
Will the 2014 primary curriculum involve any new tests? The Department for Education is currently in the process of reforming KS2 tests, but details have not yet been published.
7
Could it all be too much for some children? ‘We make no apologies for having high expectations for our children,’ ‘We believe they can achieve more, and we will not stand by and allow pupils to lose ground with their peers in countries across the world.’
8
For most children, these changes will take effect from September 2014, but children in Years 2 and 6 will follow the existing programmes of study until September 2015 in English, maths and science.

10
New Curriculum 2014 The new curriculum represents a substantial increase in both the amount of Maths being taught and the expectations of children at each age range. In general, much of what was traditionally taught in Y5/Y6 (3-digit multiplication using formal written methods, formal column addition and subtraction of 4-digit numbers as well as amounts of money, time intervals involving 24 hour clock, two-place decimals...) now has to be completed and may be assessed by the end of Y4.
11
Year 6 By the end of Y6, the children may be assessed on addition/subtraction of fractions including mixed numbers, multiplication and division of fractions by integers, formal algorithms for multiplication and division of four-digit by two-digit numbers, as well as more advanced calculations involving decimals and percentages, for example using the fact that 3/8 is 0.375.
12
Calculation Strategies To be able to choose an appropriate method for calculation e.g mental, mental with jottings, expanded written, formal written, calculator. To develop efficient methods of calculation with all four operations. To develop a mathematical understanding, a feel for the value of number rather than just learning a mechanical method that can be prone to error. We want pupils: To develop learners for life Aims To develop an understanding of the expanded and formal (traditional) methods we teach at school for addition, subtraction, multiplication and division.
13
Calculation At school we want the children to have: To be able to count efficiently Good understanding of Place Value To use images and models To use memorised number facts To Double/Halve
14
1. Place Value Common errors: Write 101 in figures (1001) 3.4 x 10 (3.40) Write one pound and 5p as a decimal (1.5) 0.2 x 0.2 (0.4) It is so important that children at KS1 have sound understanding of place value to be able to use written calculation methods at KS2 (examples on next slides)

Subtraction Partitioning: This method links to counting back on a number line. 74 - 27 = 74 - 20 = 54 54 - 7 = 47
23
Subtraction Expanded Method – No adjustment or decomposition needed: 563 - 241= 500 + 60 + 3 200 + 40 + 1 _ 300+20+ 2= 322
24
Subtraction Expanded Method – Adjustment from the tens to the units: 563 - 246= 500 + 60 + 3 200 + 40 + 6 _ 300+10+ 7= 317 1350

3. Memorised Number Facts Fewer children come to school knowing rhymes/numbers etc. Memorisation is the grounds on which we build maths. 78+5= by year 3 children should not be counting on in ones but know that 2 more is 80 plus another 3. If children don’t know their number facts, they can’t do maths.
50
4. Double and Halve Why is doubling and halving important? It is the simplest maths function we teach. We do this and then it is reversed. 1 million divide by 8 How would you do it? Halve, Halve, Halve it 13 divided by 5 How? Divide by 10 and double it.
