Korumburra Secondary College Case Study
Algebra, Differentiation and the PLT
South Gippsland Maths Initiative 2009 Ideas that resonated
• From inference to evidence
• Data led collaborative inquiry
• PLT – sharing
- “Our” students not “my” students
• importance of team leadership
- Purpose
- Process
- Structure
Coaching 2009Effect/influence of coaching • focus on the main idea/s for each lesson/unit
• Development of differentiated tasks/activities
• How will I know what students have learnt?
• Reflection with the coach after the lesson
• Model these coaching ideas with members of my staff
• PLT focus – staff to try at least one of the activities with their classes and provide feedback
Last year 2010• Development of units which include
- pre-tests
– a move away from text driving teaching and methodology
- data collection at relevant times
- focus on the big ideas and links to the developmental continuum
- one task which allows for differentiation
- starting to listen for the “golden question” and its implications for my practice.

Practices
PLTs at Korumburra SC
•The Mathematics Year 7/8 PLT comprises 5 teachers; one who teaches two year 7 classes, one who teaches two year 7 classes and one year 8 class, the PLT leader who teaches a year 7 and a year 8 class, and 2 teachers who each teach a year 8 class.
•PLT members vary in teaching experience from 2 to 30 plus years. Two of the three teachers teaching Year 7 classes have less than 5 years of Mathematics’ teaching experience. PLT meetings are held every fortnight for 1 hour after school. Occasionally PLT members have to attend other PLT meetings scheduled for the same day e.g. Year 7 PLT.
PLT structure• Ideally the PLT should –• have between 4 and 6 members• have a dedicated meeting every fortnight commencing at
the start of period 6 and continuing until 4.30pm. PLT members are covered for period 6 classroom duties.
• have teachers teaching more than one class per year level. Teachers can trial and embed their practice.
Structure of fortnightlyPLT meetings
1. Group check in: • What’s been happening in your classroom in
the last fortnight. What learning have you observed in the content area?
2. Mathematics content learning
• Semester 1 focus : fractions
• Semester 2 focus : algebra
• Readings, research, VELS
• Classroom observations/ modelled teaching
Present the power of algebra as being a general rule to show relationships between variables. The relationship holds no matter what numbers we input.Students have a strategy to explore relationships between variables.What is the effect of the National Curriculum on planning in Algebra?
The use of concrete materials : to model a scenario: give all students an opportunity to access a task, predict and check/verify: to generate a table of values: physically manipulate – scaffold learning from concrete to abstract- keep a picture in students’ heads [a visual tool] – a way to visualise different strategies /solutions which helps to see equivalence of methods e.g. Max’s, Leanne’s and Di’s solutions to matchstick patterns
When reviewing number develop number propertiesApplying number properties to patterns and pronumerals – equivalence– structure and use these to develop understanding of numberProvide opportunities for students to explore in a safe learning environment Explore strategies that students use, validate and verify them, explaining their thought processes, giving students ownership of the direction of the conversation i.e. look for “golden questions”.Use data to find out where students are on the “algebraic continuum” so we can plan our teaching and learning experiences to meet the needs of all students and progress their learning.
What is important to consider in the teaching of algebra in Year 7?

PLT process• Teachers bring agreed work sample to
meeting (pre-assessment task to begin cycle)
• Teachers share work samples across all classes using agreed process (e.g. rubric)
• Select a group of like students and examine evidence of what students can do, are on verge of doing
Zone of Proximal Development - zpd• Vygotsky’s construct of the Zone of Proximal Development - “ a state of
readiness”.
• The zone where success had odds of 50:50 pointed to the location on a continuum or trait where intervention had the best chance of assisting development. [George Rasch]
• Intervention is based on a generalised development not on a specific item-based interpretation of learning (or lack of learning).
• As a result intervention can be linked to appropriate provision of resources leading to informed curriculum and learning policy.

• Questions/Areas to investigate which may arise during the use of the Algebra Story Board [Longest Lunch context]
• clarification of information e.g. tables are side to side
• interpretation of the pattern given in words into symbols e.g.
“the number of chairs is the number of tables times two plus grandma and grandpa” means
c = t x 2 + 2 “the number of chairs is equal to two times the number of
tables plus two” means c = 2 x t + 2 or c = 2 x ( t + 2 )
Are these three equations the same? How can you check?
Number of tables t
1 2 3 4 10
Number of chairs c
4 6 8 10 22
c= t x 2 + 2 c= 1x2 + 2 = 4
c= 2 x t + 2 c= 2x1 + 2 = 4
c= 2 x (t + 2)
c= 2x(2+2) = 2x(4) = 8
If there were 20 tables, how many chairs would be needed?
Can you explain why the answer is not 44 [i.e. 2 x 22 as there were 22 chairs for 10 tables]?
How many tables are needed to seat 122 people?
How many triangular table would seat 122people?
From the point/line graph the connection between gradient and y intercept and the rule/equation can be investigated.

Necklaces Task Yr 7 What students can do and implications for teaching.
Teams owning the work
• This PLT model will work if it• is supported by school leadership teams and
resourced• is owned by the teachers involved (their
data, their students, their classrooms)• has an effective team leader who is
committed to the work (team leader may not be the domain leader).
• Discussion as a starting point for a unit of work “What are the big ideas of a topic?”
• Mapping the content in VELS
• Knowledge and use of the mathematics continuum to selecting suitable tasks to identify students’ ZPD
• Use of data and evidence to have substantive conversations about student learning
• Use of data and evidence to challenge current practice
Implementing the Action Plan – How do we know it is working?
•Use of common language when discussing our students
• Ongoing and opportune sampling of students’ work
• Teachers suggest strategies to support like students
• Identifying gaps in teacher knowledge and strategies for addressing these gaps
• development and use of “rich tasks” by teacher/s
Implementing the Action Plan
A sustainable approach to PLTs in South Gippsland Secondary
Schools• Having a common approach across all schools in the South Gippsland Region is a powerful strategy
•Team leaders meeting regularly across schools helps to develop leadership skills and promote collaborative learning and provides opportunity to practise PLT skills
Where to in 2011?• Students directing the learning/ collaboration/ follow up
on “golden questions “ • What is the learning from our students’ perspectives ?
• Development of a Year 9/10 PLT • Have a dedicated meeting every fortnight commencing at
the start of period 6 and continuing until 4.30pm. • Development of a PLT folder
• The PLT leader uses a network of other PLT leaders to continue their own skill development
