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?
SLIDE 2
SLIDE 3
What would be most useful? What are the challenges in supporting at
home?
SLIDE 4
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

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

“The ability to calculate mentally using a
range of strategies is recognised as the basis
- f being numerate.” Derek Haylock
His book is: Mathematics Explained for
Primary Teachers
SLIDE 13
“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.”
SLIDE 14
“…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.)

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

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

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 separately then recombine Double 21 Double 20 = 40. Double 1 = 2 Recombine: 40 + 2 = 42 Doubling is equivalent to multiplying by 2. Double 20 = 40 20 x 2 = 40.
