Parent Workshop: Supporting Your Child In Mathematics All - PowerPoint PPT Presentation

 Parent Workshop: Supporting Your Child In Mathematics  All materials used will be displayed on the school website shortly after the meeting

 James Wiltshire  Headteacher – Muswell Hill Primary School

 What would be most useful?  What are the challenges in supporting at home?

 To develop understanding of ‘ expectation in calculation .’  To develop understanding of the strategies involved in multiplication.  To develop understanding of how to support at home.  Please see the MHPS calculation policy for further details: http://muswellhillprimary.co.uk/wp- content/uploads/2014/01/Mathematics- Calculation-Policy.pdf

 The debate  Multiplication: expectations in KS1  Multiplication: strategies for teaching in KS1  Multiplication: supporting you  Reflection and questions

 Can you do a calculation without doing any part of it mentally?

 52 + 7  17 + 33  150 + 50  190 + 95  19 + 37  2007 – 998 =

 “The ability to calculate mentally using a range of strategies is recognised as the basis of being numerate.” Derek Haylock  His book is: Mathematics Explained for Primary Teachers

 “Make it clear that there is no ‘proper’ way of doing mental calculation and that an effective mental or informal method is as valid as a formal written method.”

 “…this does not mean of course that they do not write anything down…”  They may need to write the question so they don’t forget it.  They may write a few jottings (key information.)  Support with a picture or numberline

Expecta ctati tion on by En End Of Y2 Example le – where here neces cessary ary  The Standard – Mental Maths: Count in 2’s, 5’s and 10’s. See the next slides Multiplication facts for 2,5 and 10 Up to 2 x 12, 5 x 12 and 10 x 12 times tables. Know the corresponding division 2 x 6 = 12. 12 divided by 6 = 2 facts for 2,5 and 10 times tables. Understand that multiplication is 4 x 5 = 20 and 20 divided by 4 = 5 commutative but that division is 5 x 4 = 20 but 4 divided by 20 is not. not 5 Count in 10 from any number. 13, 23, 33, 43, 53… Click here… Number Grid ITP

 Fizz  Objective: To understand multiples of 5

 Fizz, Buzz  Objective: To understand multiples of 5 and 3

Expecta ctati tion on by En End Of Y2 Example le – where here neces cessary ary Calculate doubles of all numbers to Double: 1,2,3,4,5 etc 10 then 20 Double: 11, 17, 19 etc Know halves of all even numbers to Halve: 4,6,8,10 etc 10 and 20 Halve: 14,18, 20 etc Know odd and even numbers to 20 Odd: 17, 15, 19 and then 100 Even: 12, 14, 8 Odd: 77, 65, 43 Even: 24, 66, 44

Expecta ctati tion on by En End Of Y2 Example le – where here neces cessary ary Double multiples of 5 and 10 Double 25, Double 60 Halve any multiple of 10 up 100 Halve 90, Halve 30. Partition double tens and ones Double 21 separately then recombine Double 20 = 40. Double 1 = 2 Recombine: 40 + 2 = 42 Doubling is equivalent to Double 20 = 40 multiplying by 2. 20 x 2 = 40.
