2. Activity 1 Take a card
Find the answer to the algorithm/problem
(if you need a calculator move on)
Create a question using the algorithm/problem
3. Purpose of the activity Where any of the algorithms DIFFICULT?
Would you expect your students to be able to do these?
All from NAPLAN 2009 – Did you recognise them?
Why are they different?
4. Newman’s Error Analysis Reading
Can students read the words of the problem?
Comprehension
Can students understand the meaning?
Transformation
Can students determine a way to solve the problem?
Process Skills
Can students do the mathematics?
Encoding
Can students record and interpret their answer?
5. Newman’s Prompts Read the question. read
What does it mean? mean
What will I do to solve it? do
Do the maths. maths
Write the answer. answer
6. Common Practice Research carried out in Australia and Southeast Asia suggests that about 60% of students’ errors in responding to written numeracy questions occur before students reach the process and encoding skills level. (i.e. before Newman steps 4 & 5)
However 80% of remediation programs and common teaching practice is to focus students on revision of process skills. (Newman step 4)
7. National Numeracy Review Report (2008) From the earliest years, greater emphasis needs to be given to providing students with
frequent exposure to higher-level mathematical problems
rather than routine procedural tasks,
in contexts of relevance to them,
with increased opportunities for students to
discuss alternative solutions
and explain their thinking.
8. What does this mean for us? If we continue to remediate ONLY algorithms (like the Activity 1 questions) there is little chance of student outcomes improving.
9. So what do we do? Help students to ………
- read the questions
- comprehend what they read
- provide strategies that aid understanding
- teach students to answer multiple choice questions – many guess or are mislead.
10. How can we do this? Focus on worded problems
Increase the metalanguage used
Get students explaining how they get answers
Scaffold strategies
Assessment for learning
Explicit teaching of concepts
11. Explicit teachingof mathematical terms & symbols Students need to say new words as well as hear and see them.
How do you verbalise 7- 5?
7 minus 5
7 take away 5
take 5 from 7
from 7 take 5
subtract 5 from 7
12. Understanding the vocabulary Words that are only used in mathematics
eg. parallelogram
Words that have the same meaning in mathematics as in everyday language eg. equal
Words that have a different meaning in mathematics as in everyday language eg. volume
13. Significance of context and positional terms in mathematics Instead of concentrating on key words, students need to look at the words in the context of the whole problem.
Five is how many more than three?
Five is three more than which number?
Which number is three more than five?
Prepositions can change meaning and the choice of process-
What is half of 4? Four is half of what ?
Increase by 7, Increase from 7, Increase to 7
14. Consider literacy strategies HERE – require literal comprehension of directly stated information
“reading ON the lines”
HIDDEN – require interpretation of information
“reading BETWEEN the lines”
HEAD – require inferences to be made and
information to be evaluated and applied
“reading BEYOND the lines”
15. A lack of concept knowledge An 11 year-old student explained this approach to solving written questions in numeracy:
"Problem solving is easy.
If there are more than two numbers, I always add;
otherwise, I subtract.
If I'm not sure if it's multiplication or division, I divide and,
if there is a remainder, I multiply instead"
(Hope, 1987, p. 57).
16. Another light moment !!!
17. Assessment for learning Mathematics is sequential – learnt work is the building blocks of new learning.
Find out what students know and program the learning to the next level.
18. Using SMART data SMART data is a great tool to analyse where to start.
Using Item Analysis you can find where your students differ most from the state – this is usually a good starting point.
19. Who is best to analyse the NAPLAN data? The teachers.
What should they look for?
Strengths & weaknesses
Individual performances
Find out what students know
Find out what has to be taught
Are the NAPLAN results a true indication
If NOT why?...... It is not the test, it is consistent acros the state, so it gives a good “yard stick”

23. Tape Diagrams Students draw a tape to support their thinking during problem solving
24. To get to work, I travelled on the train for 24 minutes and I walked for 7 minutes. How long did it take me to get to work?
This is how a student represented the problem using a tape diagram.
Points to note:
Tape diagram enables us to represent all the relevant information
It is only a diagram to help us visualise the transformation of the problem, so being precisely accurate is not necessary
As a means of organising, I like to place above the tape information about the whole tape and below it information about its partsThis is how a student represented the problem using a tape diagram.

25. There were some oranges in a box. Because we bought 14 more oranges, there are now 21 oranges in the box altogether. How many oranges were in the box at first?
Reveal ‘There were some……………….’
Task Draw a tape diagram for this problem.
Reveal diagram.
This is how a student represented the problem using a tape diagram. Questions where the answer is not the largest number create particular problems for many students.
