4 Maths is one of the core subjects taught in primary schools. Each child receives approximately five hours of Maths lessons a week, with additional Maths fluency time during the day and Maths skills used in other subjects.

5 The Maths that we teach comes directly from the current National Curriculum. The programmes of study slightly differ between Years 1-6 but generally they include a focus on: Number and place value Addition and subtraction Multiplication and division Fractions (including decimals and percentages Yrs 4-6) Measurement Geometry: properties of shapes, position and direction Statistics Ratio and proportion (Year 6) Algebra (Year 6)

6 Key maths objectives have been sent out for your year group.

8 What will the children need to be able to do by the time they leave Year Six? The arithmetic paper:

9 What will the children need to be able to do by the time they leave Year Six? The reasoning paper:

10 If children are not taught calculation methods then they do not have the necessary tools to complete maths problems.

11 What mistakes has the child made? Why have they made these mistakes?

12 What mistakes has the child made? Why have they made these mistakes?

13 If children are not taught a consistent approach to written calculations, where they understand the processes behind the calculation and build upon this knowledge, it will lead to the child making errors and becoming confused.

15 Year One Addition: Combining two parts to make a whole one.

16 Year One Addition: Starting at the larger number and counting on.

17 Year Two Addition: Starting at the larger number and counting on using partitioning.

18 Year Two Addition: Starting at the larger number and counting on using partitioning. Initially record each jump of ten and jump of one. Then lead into one jump of a multiple of ten and one jump of a multiple of one.

19 Year Two Addition: Adding three numbers together, looking to make 10 first.

20 Year Three Addition: Adding two digits using partitioning.

21 Year Three Addition: Beginning to use the column method without regrouping = =

22 Year Three Addition: Beginning to use the column method without regrouping.

23 Year Three into Year Four Addition: Beginning to use the column method with regrouping.

24 Year Three into Year Four Addition: Beginning to use the column method with regrouping. Leading onto the standard written method but with partitioning.

25 Year Three into Year Four Addition: Beginning to use the column method with regrouping. Leading to the standard column method:

26 Year Five and Year Six Addition: Confident with standard method and with adding more than one number.

27 Year Five and Year Six Addition: Adding numbers with different lengths, including decimals.

28 Year One subtraction: Physically crossing out ones.

29 Year One subtraction: Counting back in ones

30 Year One subtraction: Using ten to help count back.

31 Year Two subtraction: Starting at the bigger number and counting back in multiples of ten and multiples of one.

32 Year Two subtraction: Finding the difference

33 Year Three subtraction: Partitioning and column method without regrouping.

34 Year Three into Year Four: Column method using exchanging.

35 Year Three into Year Four: Column method using exchanging.

36 Years Five and Six subtraction: Column method including decimals.

Written calculation methods for multiplication and division. 5. How else can parents support their children with Maths?

38 Year One multiplication: repeated grouping 4 x 3 can be shown as

39 Year Two multiplication: using number lines to show repeated grouping

40 Year Two multiplication: using arrays

41 Year Three multiplication: using partitioning

42 Year Three multiplication: using partitioning

43 Year Four multiplication: partitioning and grid method

44 Year Four multiplication: moving into a formal method.

45 Year Four and Year 5: short multiplication

46 Year Five multiplication: short multiplication

47 Year Five and Year Six: Long multiplication

48 Year Five and Year Six: multiplication with decimals.

49 Year One division: sharing

50 Year Two division: repeated grouping and subtraction

51 Year Two division: answers with remainders 13 divided by 4 =

52 Year Three division

53 Year Three division: partitioning Two digit numbers divided by 1 digit (no remainders) using base 10. Partition the two digit number into tens and ones and then divide by the single digit.

54 Year Three division: partitioning Partition the numbers into tens and ones and then divide by the single digit: Moving onto abstract calculations with partitioning using known number facts e.g = = = = 14

55 Year Four division: linking to arrays and grid method to move onto the short method.

56 Year Four and Year Five division: moving onto short method with exchanging.

57 Year Five division: short method showing remainders as a remainder or a fraction and rounding remainders up or down. Problem solving will involve rounding in context: There are 432 guests at a wedding. Each table at dinner seats 15 people. How many tables are needed?

58 Year Six division: Short method showing the remainder as a fraction and a decimal.

59 Year Six: long division

60 Year Six: long division

62 How can children be supported at home? Be consistent with the written methods used by school when supporting your child with homework. Check that tutors are also being consistent lots of different methods leads to a child being confused! Please tell tutors to visit our school website. Ask your child to teach you the method! If they can explain it then they can understand it. Repeat their instructions but make deliberate errors can your child mark your work and explain where you went wrong?
