Learning Outcomes

The learning outcomes are to confirm ability to:

  • apply a wide range of mathematical concepts and techniques to solve mathematical problems including:
    • using ratio, proportion and percent
    • using trigonometry to determine lengths and angles
    • using basic indices
    • using measurements to solve mensuration problems in two and three dimensions
    • substituting into and transposing simple equations and formulae
    • presenting and evaluating statistical information
    • identifying connections between formulae and graphical representations
    • using algebraic techniques to analyse and solve problems
  • apply estimation to check calculations and reasonableness of problem solving outcomes
  • use mathematical symbolism, charts, diagrams and graphs to convey mathematical thinking and processing.

Details of Learning Activities

This unit is part of the Diploma of Teacher Education Preparation program. The learning and assessment in the program is delivered through face to face teaching, Unsupervised Directed Study and participation in work placement. It is strongly advised you attend all sessions in order to engage in the required learning activities, ensuring the maximum opportunity to gain the competency. You are not required to attend to complete Unsupervised Directed Study, however you are expected to complete the work given and will at times be required to show evidence the work has been completed. Your Unsupervised Directed Study will be posted on Canvas.

The student learning experience will be facilitated through participation in a range of activities:

  • Group discussion
  • Question and answer tasks
  • Assignments
  • Practical demonstrations and direct observation of actual work and simulated work practice
  • Oral presentations
  • Individual and group projects - Completing the projects will include negotiated independent study time and practical work relevant to the unit of competency.  

Teaching Schedule

This unit will be delivered weekly.  
Please note: While your teacher will cover all the material in this schedule, the weekly order is subject to change depending on class needs and availability of speakers and resources. Should the teaching schedule change students will be advised via Canvas.
Library Orientation & an RMIT Online Systems Information Session will be scheduled during the first two weeks of your program. Information about student services, rights and responsibilities is available on the RMIT website

Learning Resources

Prescribed Texts


Other Resources

RMIT will provide you with resources and tools for learning in this course through handouts, our online systems and access to facilities and relevant software. You will also have access to the library resources. It is recommended that you bring:

  • Display folder with plastic sleeves
    • Highlighter pens
    • Notebook or loose leaf paper
    • Headphones

Overview of Assessment

You must demonstrate the critical aspects of assessment and evidence required for the Unit in order to be deemed competent. Assessment methods have been designed to measure achievement of each competency in a flexible manner over a range of assessment tasks. You may be assessed by: 
• Oral or written questioning 
• oral presentations
• Assignments and projects 
• Direct observation and demonstration in actual work practice 
• Presentation of a portfolio of evidence which may comprise documents, and/or photographs and/or video and audio files 
• Work-based activities 
• Third-party feedback from a work supervisor/employer 
Feedback will be provided throughout the semester in class and/or online discussions, through individual and group feedback on practical exercises and by individual consultation. 

If you have a long term medical condition and/or disability it may be possible to negotiate to vary aspects of the learning or assessment methods. You can contact the program manager or the Equitable Learning Services if you would like to find out more.

The Student Charter summarises your responsibilities as an RMIT University student as well as the responsibilities of the university.

Your course assessment conforms to RMIT assessment principles, regulations, policies and procedures which can be found on the RMIT University website at:;ID=qwxbqbg739rl1

Assessment Tasks

Assessment Tasks - Semester 1

Assessment 1 – Proportions, Statistics and Graphs Test (Week 9)

Assessment 2 – Straight line and Non-linear equations Test (Week 16)

Assessment tasks in this unit are assessed using the following competency based results:

CA - Competency achieved
NYC - Not Yet Competent

All Assessment tasks should be submitted by the due date. If an extension is required please contact your teacher and/or Coordinator before the due date. 
You must complete a submission cover sheet for every piece of submitted work.
All assessment tasks including electronically recorded student work will be kept by the University for student feedback and to meet government requirements.
If you are found to be Not Yet Competent in a Course Assessment Task you may be allowed one resubmission only. Your teacher will provide feedback regarding what you need to do to improve and will set a new deadline for the resubmission. The highest grade you will receive if your resubmission is successful is 'CA'

Assessment Matrix

The assessment matrix demonstrates alignment of assessment tasks with the relevant Unit of Competency and with the critical aspects of assessment for each unit. A copy of the assessment matrix is available for all students. 

Other Information

Attendance - The major learning experience involves participating in face to face classes. It is strongly advised that you attend all sessions in order to engage in the required learning activities, ensuring the maximum opportunity to gain the competency.
Feedback - Monitoring academic progress is an important enabling and proactive strategy to assist you to achieve your learning potential. Students may be asked to attend interviews with relevant teachers and Program Coordinator to discuss academic progress.
