Title: To Be Numerate


1
To Be Numerate
  • Maths Information for Parents

2
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

3
Goals We want our students to
  • Develop multiple flexible thinking strategies
  • Use mental strategies and confidently explain
    orally before written standard vertical forms
  • Use a range of strategies and make decisions
    about using the most effective strategy to work
    out any given problem.
  • Achieve and develop a positive attitude towards
    learning mathematics while enjoying the challenge
    of problem solving

The Balance of Strand
Number and Algebra is the most important
strand. The balance shifts as students progress
through the stages. A guide to this is
Stages Time Spent on Number and Algebra Time spend on other strands (Geometry and Measurement, Statistics)

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.

9
Knowledge and Strategy
  • Knowledge
  • Number Identification
  • Number Sequence and Order
  • Grouping and Place Value
  • Basic Facts
  • Strategy Three domains
  • Addition and Subtraction
  • Multiplication and Division
  • Ratios and Proportions

10
Knowledge Before StrategyIt is essential that
students have sound knowledge for the strategies
they are developing e.g.
Knowledge Strategy
Stages 1-3 Numbers to 20-order, before and after Counting all to solve addition, subtraction and multiplication problems to 10
Stage 4 Numbers to 100- order, before and after Skip counting in 2s, 5s and 10s to 100 Addition and Subtraction to 100 by counting on and counting back Skip count to solve multiplication problems
Stage 5 Numbers of tens and hundreds in three digit numbers Knows 2, 5 and 10 x tables Use place value to solve addition and subtraction problems Apply simple multiplication facts to solve problems
11
Developmental Stage Progression
  • The New Zealand Number Framework

16
How is maths taught differently now?
17
Teaching Model
  • Model and support childrens understanding using
    a researched teaching model
  • Steps for when a new strategy is introduced
  • i. Using materials ii. Thinking about
    what would happen on the materials
    iii. Working only on numbers and applying
    strategy to higher numbers
  • Teach to achieve next learning steps

18
Using EquipmentThe use of equipment is essential
when developing new strategies
  • Bridging to Ten
  • Happy Hundreds

One to One Counting Stage 1
23
Count From One on MaterialsStage 2
There are 4 counters and another 3 counters. How
many are there altogether?
1,2,3,4,5,6,7 The child solves the problem by
using their fingers or other materials and counts
from one.

Advanced ProportionalStage 8
You can make 9 mittens from 15 balls of wool.
How many mittens can you make from 10 balls of
wool?
The child sees that 915 are both multiples of 3.
They simplify by 3 and get a ratio of
35 ?10 6 The child can select from a wide
range of strategies to solve challenging problems
involving, decimals, fraction percentages and
ratios.
30
Assessing what children know
  • Teachers use a variety of tasks (informal and
    formal) to form our Overall Teacher Judgements
    (OTJs)
  • Group according to a childs strategy stage using
    the New Zealand Number Framework
  • Encourage children to self assess (reflect) know
    and own their next learning steps. (Personalised
    Learning)

How do we cater for individual learning needs in
Maths?
  • Using a variety of assessments and analyse data
  • Grouping and teaching according to learning needs
  • Individual Learning Goals
  • Cross grouping in the middle and senior classes
  • Personalised Learning Programmes

41
How can parents help?
  • Developing a childs knowledge is a key to their
    success and development in mathematics This is
    the perfect area for you to help and support your
    child at home
  • Knowledge lists for each stage and activities are
    on our school website
  • Encourage your child to spend 10 minutes a day or
    3x 20 minutes a week on Mathletics

42
Knowledge Building
These activities can be used at all levels just
use different range of numbers for different
levels
  • Counting(cars, shells on beach, pegs, run around
    the house, how many steps you walk, count
    backwards, start from different numbers, skip
    counting groups of objects e.g. pairs of shoes )
  • Numbers before and after(Letter boxes, say a
    number, use a number line, use number cards,
    write a number down, ladder game, keyboard
    numbers, using dice)
  • Identifying numbers(Letter boxes, number plates,
    speed signs, how many km to go, number cards,
    combine numbers, odometers, metres)
  • Ordering numbers(Number cards, write some
    numbers down, cut up calendars)

43
Knowledge Building cont..
  • Knowing Groups of ten (Using ten frames, using
    fingers, abacus, ice- block sticks)
  • Recalling Doubles and Halves (ten frames,
    fingers, flashcards)
  • Basic addition subtraction facts to 5, then
    10, then 20 (Buttons, ten frames, fingers,
    flashcards, number boggle, playing cards)

44
Finger patterns
45
The Reality?
To become a Part-Whole thinker (stage 5 plus)
children need automatic recall of
  • Facts to Ten (addition and subtraction)
  • Doubles Facts
  • Ten and .10 6 16
  • Groups of ten (Place Value)

To become a Multiplicative thinker (stage 7)
children need automatic recall of
  • All of the above
  • The times tables

46
It may surprise you to know.
  • Algorithms are okay but only when
  • A student shows an understanding of how they work
    e.g. 73 - 59 involves renaming 73 as 6013
  • A student reaches end of Stage 6
  • It is an effective method for the problem posed.
  • e.g. Try working out this out as an algorithm
  • 10004 or 199
  • - 9998 99
  • They also know other strategies they can use
  • They are achieving at Stage 6

47
It may surprise you
  • In Stage 1-4 We focus on learning our addition
    and subtraction facts to 10
  • At Stage 3-4 We focus on developing
    understanding of multiplication and division (not
    learning the multiplication division facts)
  • At Stage 5 Students learn addition facts to 20
    subtraction facts to 10
  • 2x, 5x and 10x multiplication facts
