6. Working Mathematically
Understanding:
Build a strong foundation, understand the ‘why’ and ‘how’ of mathematics, make connections, compare and interpret information
Fluency:
Calculate efficiently, choose appropriate methods, recall definitions and facts, manipulate data to find solutions

7. Stage Statements, Outcomes and Content
Early Stage 1: Kindergarten
Stage 1: Year 1 and 2
Stage 2: Year 3 and 4
Stage 3: Year 5 and 6
Continuums - different instruction for different needs
“The syllabus is written with the flexibility to enable students to work at different stages in different strands. For example, students could be working on Stage 4 content in the Number and Algebra strand while working on Stage 3 content in the Measurement and Geometry strand”

9. Key Ideas
Understanding is the key - students need to be able to use mental strategies and not just learn things by rote.
Students need to be aware that there can be more than one way to answer a question.
Opportunities at home to improve numeracy skills include budgeting, shopping, reading timetables, handling money and cooking to work out quantities. Do not do the work for them, they need to develop skills.
Pinpoint the problem, ask them which strategy they would use.
Learn and practise times tables; so much of stage 2 and 3 maths relies on students having fast and accurate recall.
Stay positive and contact your child’s teacher when you have concerns.

13. How we teach it in the classroom Focus in on mental strategies

14. How we teach it in the classroom

15. Differentiation Emergent Counting Cannot count visible items
Does not know number words
Perceptual Counting
Counts items using concrete materials
Counts visible items to find the total
Objects remain in view while counting
?Figurative Counting
Visualises concealed items and counts from 1.
May use fingers if concealed items are greater than 10.

16. Differentiation cont... Figurative Counting
Visualises concealed items and counts from 1.
May use fingers if concealed items are greater than 10.
Counting On and Back
A number takes place of a completed count e.g ; 6 and 7,8,9,10,11.
Fingers may be used when counting on.
When students reach the counting on and back phase they can now ?begin to work on and understand place value.

17. Differentiation cont... Facile Strategies
Uses known facts, number structure and other non counting by ones strategies to solve number problems.
E.g. Bridging to 10, 'friends of 10 and 20', compensation, doubles and near doubles, split, jump etc.

18. Examples of classroom games that teach mental strategies:

19. 27

20. Mental strategies for addition and subtraction
Jump Strategy Split Strategy -
Compensation Strategy ; = 93; subtract 1 to obtain 92
Bridging the decade ; is 44; = 51
Using patterns to extend number facts - 5 – 2 = 3; so 500 – 200 = 300

21. Using cards at home to help your child:
Headache:
Another fun game to play with your family to develop student's understanding of number and the relationship between addition and subtraction.
21:
Turn two cards and add together, how many more to make 21? Change the total and the number of cards turned to make harder, or use two cards to make one 2-digit number e.g. turn over a 4, 6, 8, 6 and turn into 46 and 86.

22. How can I help my child at home?
Look for opportunities in everyday life:
Play games with cards such as 21.
Play dice games using number die as well as dot die.
Start asking your child to think about ways to count faster e.g. counting on, counting by 2’s, counting by 5’s.
Ask addition and subtraction questions e.g. Set the table for one person and ask your child to put out enough plates for everyone. Ask them how many more were needed.
Ask your child to help you work out how many more items are needed when you are shopping. "I have six apples here, how many more will I get to make 10?"

24. Stage 2 Stage Statement - by the end of the stage
students ask questions and use efficient mental and written strategies with increased fluency to solve problems.
Count, read and order numbers up to five digits
Use informal and formal written and mental strategies to solve addition and subtraction problems
Use mental strategies to recall multiplication facts up to 10 x 10 and related division facts
Use informal written strategies for multiplication and division of two-digit numbers by one-digit numbers
Represent, model and compare commonly used fractions and model, compare and represent decimals of up to two decimal places
Perform simple calculations with money and solve simple purchasing problems
Record , describe and complete number patterns and determine missing numbers in number sentences
Estimate, measure, compare, convert and record length, area, volume, capacity and mass using informal units
Read and record time in hours and minutes,convert between units of time and solve simple problems involving the duration of time
Name, describe and sketch particular three-dimensional objects and two-dimensional shapes
Compare angles using informal means and classify them according to their size
Use a grid reference system and make simple calculations using scales on maps and plans
Collect and organise data and create and interpret tables and picture and column graphs

25. How we teach it in the classroom
Continue with strategies used in ES1 and Stage 1 - guided, modelled and independent
Incorporate formal algorithm
Continue to use concrete materials and give opportunities to have hands on experiences
Focus on using mental strategies
There is a big emphasis on language in all strands of maths

26. Differentiation This includes grouping to suit various levels
Grouping allows for flexibility and the grouping is fluid, allowing for movement
Games and discussions - how did you get the answer?
Think why and question - is there another way to get the answer? We might choose 3 or 4 children to share how they arrived at the answer.

27. Classroom Activities Games - dice game
Mabble - a maths game which is like Scrabble but it uses the four operations:
addition, subtraction, multiplication and division. Points are awarded when the totals of the digits are added. There are points awarded for the actual algorithm. Addition, subtraction, multiplication and division receive 1, 2, 3 or 4 points respectively. The winner is the person with the most points.

28. How to help at home Playing shop
Kitchen scales - estimate then weigh items
Have dice at home
Use pegs, cutlery, beads and other items to create patterns
Put a wall measuring chart up and measure family members; plot heights and update from time to time
Look at and say numbers in the environment
Use different numbers as a starting point for counting - count forward or backwards from this number. Increase difficulty as child gains proficiency; count forward and backwards off the decade and in hundreds
Cut fruit, pizza and similar foods into pieces and name the fraction
Look at calendars - count down days to a special event
When you are watching sport - discuss how the score is tallied. How long does the game go for? Is it divided into halves, quarters or is there another way it is measured
Map the weather - keep a log of the week’s temperatures. Older children could keep a log of a month’s temperatures and work out the average. Look and see what time the sun rises and falls over a period of time so that they are gaining an understanding of the length of a day during the different seasons
Look at recipes: discuss the use of fractions, millilitres and grams in cooking
Discuss how you would double a recipe
Collect Coles and Woolies catalogues - there is a lot of maths that can be derived from these
Calculate change when you are shopping

29. Stage 3 Stage Statement
Mental, written and calculator strategies for the four operations
Big focus on fractions, decimals and percentages
Order of operations
Number patterns, prime and composite, square and triangular
Four quadrants of the Cartesian plane
24 hour time, capacity, volume, converting between measurements
Timezones and elapsed time
Grid-reference system for maps and directional language
Collect, analyse data
Probability and simple chance experiments

30. How do we teach it in the classroom
Differentiated
Direct instruction for new concepts and skills
Move to open ended, problem-solving contexts
More formal recording/ setting out
Proof and evidence
Flexibility in thinking - examining more than one solution
Preparation for high school mathematics

31. How do we teach it in the classroom
WHAT'S THE PROBLEM?
‘The answer to a problem is one and a half, what might the question be?’
Description of activity
Students respond to a scenario and record a variety of responses.
The teacher poses the question: Students record a variety of questions, including word problems, number sentences and questions that involve more than one operation.
They include the four operations in their questions.
