Title: To Be Numerate


1
To Be Numerate
  • Devonport Primary School
  • Parent Information Evening

2
Outline
  • Problem Solving Activities
  • How is Mathematics taught now?The New Zealand
    Numeracy Framework
  • Helpful and practical ideas to support your
    childs learning in mathematics.

3
Time to Think!!!
4
Number Strategies Subtraction
  • There are 53 people on the bus.
  • 29 people get off.
  • How many people are now on the
  • bus?

5
Solution 53 29
  • How did you work it out?
  • What happened in your head?
  • Share your different strategies with the people
    around you

6
Make sense of these strategies
I use place value 53 20 33. Minus another
9. Split the 9 into 3 and 6. 33- 3 30 6 24
I use tidy numbers 53 30 23 plus 1 24
53 29
I think of 53 -29 3 9 I cant do so I borrow
a ten. 13 9 4. 4 tens 2 tens 2. Its 24

Number Strategies Multiplication
  • There are 4 packets of biscuits with
  • 24 cookies in each pack.
  • How many cookies are there
  • altogether?

8
Solution 4 x 24
  • How did you work it out?
  • What happened in your head?
  • Share your different strategies with the people
    around you.
  • How else could this problem be solved?

9
Make sense of these Strategies.
I used place value 4 x 20 80. And 4 x 4
16. 80 16 96
I use tidy numbers I know 4 x 25
100. 100-(1x4) 96.
I think of 24 X4 4 x 4 16. Put down the 6
and carry the 1. 4 x 2 80 another ten
90 906 96
4 x 24
I know 24 24 48. 48 48 96
I used doubling and halving. Double 4 8, half
24 12. 8 x 12 96

Numeracy Project Goal
  • to be numerate is to have the ability and
    inclination to use mathematics effectively at
    home, at work and in the community
  • Published in Curriculum Update 45

11
Goals cont.
  • developing multiple flexible thinking strategies
  • mental and oral before written standard vertical
    forms
  • Make decisions about the smartest strategy to use
    on any given problem.
  • Challenge children to achieve and develop a
    positive attitude towards learning mathematics.

12
Why?
  • International results of TIMMS test in the 1990s
    were concerning.
  • Research had shown that children developed
    numeracy understandings through stages (not
    necessarily age-related).

13
Developmental Stage Progression
  • The New Zealand Number Framework

14
Numeracy Stages
  • Emergent
  • One to One Counting
  • Count from one on Materials
  • Count from one by Imaging
  • Advanced Counting
  • Early Additive Part-Whole
  • Advanced Additive Part-Whole
  • Advanced Multiplicative
  • Advanced Proportional

Counting Strategies
Non Counting Strategies
15
The NZ Numeracy Framework
  • Each Numeracy Stage highlights key knowledge and
    strategy that a child should know.
  • Strong knowledge is essential for students to
    broaden their strategies across a full range of
    numbers.

Creates new knowledge through use
Provides the foundation for strategies
16
Knowledge and Strategy
  • Knowledge Number Identification, Number
    sequence and order, Grouping and place value,
    basic facts
  • Strategy Addition and Subtraction,
    Multiplication and Division, Fraction and
    Proportions

17
How is maths taught differently now?
18
Assessing what children know.
  • Assess - where each child is at through oral
    interviewing and questioning
  • Group according to a Childs strategy stage using
    the New Zealand Number Framework

19
How can parents help?
  • Developing a childs knowledge is a key to their
    success and development in mathematics.

20
Knowledge Building
  • Counting(cars, shells on beach, pegs, run around
    the house, count backwards, start from different
    numbers etc.)
  • Numbers before and after(Letter boxes, say a
    number, write a number down, keyboard numbers,
    using dice etc.)
  • Identifying numbers( Number plates, speed signs,
    how many km to go, cooking etc.)
  • Ordering numbers(Mailbox, money, TV
    channels,ages etc.)

21
Knowledge Building
  • Knowing groups to ten(Using ten frames, using
    fingers, quinary sticks)
  • Basic addition facts to ten(Buttons, ten frames,
    quinary sticks, fingers)
  • Recalling Doubles(ten frames, fingers, quinary
    sticks)

Ten frames
Quinary Sticks
22
The Reality?
  • To become a Part-Whole thinker, children need
  • automatic recall of
  • Facts to Ten
  • Doubles Facts
  • Ten and .10 6 16
  • To Become a Multiplicative thinker children need
  • to be able to recall the x tables

23
Handouts Website -links to www.nzmaths.co.nz
and parent maths information
24
Where to now?
  • Wander around the stations that the teachers have
    set up to show you some examples of how numeracy
    is taught.
  • Try some activities and games.
  • Have fun!
  • Ask questions.
