Title: Numeracy Parent Teacher Workshop
1Numeracy Parent Teacher Workshop
- Led by John Wajdner (Numeracy Advisor)
- Assisted by Miss L. Barratt Mrs D. Hyde
- 4.11.2008
- 630 800pm
2Aims for tonights meeting
- To enable parents/carers to find out about the
mathematics their children are doing,
particularly the way they subtract mentally. - To enable parents/carers to help their children
at home.
3Firstly, thank you for a great response and a
super turn out.
4Darts Game
We first played a game of darts, which is a good
game to play, getting children to add the scores
mentally. This can then progress to subtracting
the score from a starting number.
8 2 10 10 9 19
11 6 17 17 3 20
Points to start with 50
50 19 ? 50 20 30 30 1 31
50 20 ? 5 3 2 so- 50 30 20
5Recent Reports Key Findings
- Involving parents
- More emphasis on oral and mental
- Teach for understanding
6NNS Framework for teaching mathematics has a
structured approach to calculations
- Mental counting and counting objects
- Early stages of mental calculation and learning
number facts, recording in a number statement - Working with larger numbers and informal jottings
- Non-standard expanded written methods
- Standard written methods
Now were counting in 0.7s.
Were counting in 7s.
7How Do You Do It?
Now how would I solve this mentally?
Both parents and staff worked together to solve
these calculations, then discussed their methods
of working.

- 1724 360360
- 2.5x12x2 8006-2993
- 1502 1.51.6
- 70x6 572-49

8Key Skills Needed
- bonds to 10, 20, 100 etc.
- tables
- doubling and halving
- x 10, x 100, 10 etc
- place value
- the size of a number and where it fits on the
number line
9We played a number bond game, finding pairs of
numbers with a total of 10, 20, 100 etc
I can play this at home with my children.
10Number lines game
- Aim of the game
- Get 3 numbers together along a number (do NOT
have to - be 3 consecutive numbers ie 34, 35, 36)
line first. - Rules
- Get a blank number line.
- Player 1 roll 2 dice to make a 2 digit number.
- Position the number on the number line.
- Player 2 roll 2 dice to make a 2 digit number
then position it on the number line trying to
block player 1. - Continue the game until one player has 3 numbers
together.
56 or 65
21 or 12
56
52
Player 2 would win this game as they have 3
number together.

7 x 5 35 5 x 7 35 and therefore 35 7 5
35 5 7
John modelled how times tables are so important
to know and how they help with mental
calculations.
Oh yes, now I see.
Faced with the question 700 x 5 ? Use what we
know. 7 x 5 35, so 70 x 5 350 and 700 x 5
3500.
12Higher or Lower
- This game we played with the 7 x table.
- John showed us a number in the 7 x table and
parents and staff had to guess higher or lower
according to what number was shown.

13Subtraction Targets
Year 1
Year 2
Year 3
Must Understand subtraction as take away and
find a difference by counting
up. Should Subtract mentally a single-digit
number or a multiple of 10 from any two-digit
number. Could Subtract mentally combinations of
one-digit and two-digit numbers.
- Must
- Begin to relate
- subtraction to taking
- away.
- Should
- Understand
- subtraction as take
- away and find a
- difference by
- counting up.
- Could
- Subtract mentally a
- single-digit number or
- a multiple of 10 from
- any two-digit number.
Must Subtract mentally a single-digit number or a
multiple of 10 from any two-digit
number. Should Subtract mentally combinations of
one-digit and two-digit numbers. Could Subtract
mentally pairs of two-digit whole numbers.
14Subtraction Targets
Year 5
Year 6
Must Extend mental methods for whole-number
calculations, for example to subtract one
near-multipleof 1000 from another (e.g. 6070
4097). Should Calculate mentally with integers
and decimals U.t - U.t. Could Consolidate and
extend mental methods of calculation to include
decimals, fractions and percentages.
Must Subtract mentally combinations of one-digit
and two-digit numbers. Should Subtract mentally
pairs of two-digit whole numbers. Could Extend
mental methods for whole-number calculations, for
example to subtract one near-multiple of 1000
from another (e.g. 6070 4097).

15Subtraction strategies
- Counting on and counting back
- Near multiples of ten (9, 11, 19, 21 etc)
- Equivalent calculations
- Using known facts
16What can you do?
- Be positive about maths, even if you dont feel
confident about it yourself. - Talk and listen to your child about their work in
maths. It will help your child if they have to
explain to you. - Share maths activities they take home.
- Play number games
- Help with learning number facts
