These two videos present an approach or approaches to the 2018 VCE Mathematical Methods Examination 2 – Section A, Q1 to Q10. These approaches incorporate the use of CAS as well as ‘by hand’ solution methods. At times, two alternative methods are presented. The providing of two solutions is intended to encourage a conversation between teachers and students about the most discerning and efficient way to tackle the mathematics presented in this form of assessment.
Aim: Simplify and manipulate expressions with algebraic fractions. Key concepts: Algebraic fractions ClassPad Apps: Main Activity Solution

This activity uses the same data, the heights of a group of Year 9 students. Students will use graphs to compare the heights of the two genders. The data is the same as in the previous activity. Key concepts: Draw …
Key concepts: Let’s compare two groups using statistics. Start with the raw data and draw stem and leaf plot before introducing the technology. The raw data includes some data entry errors and students have the opportunity to manage the real …
Aim: Induce some index laws based on patterns. Key concepts: Induce some index laws based on patterns. ClassPad Apps: Main Activity Solution
Key concept: Develop an understanding of negative integer powers. ClassPad Apps: Main Activity Solution
Key concepts: Use the sine, cosine and tangent ratios to solve to solve problems involving right-angled triangles. While the equations can be solved by other methods, NumSolve is encouraged here and an extension is to save the formulae in an …
Key concepts: Draw scale diagrams to solve problems involving right-angled triangles. This technique is useful whenever a scale diagram can be used to solve the problem. Apps: Geometry Activity Solution
Unpacking linear functions and coordinate geometry activities for Year 9&10. Key concepts for this activity centre on: Dynamically draw a triangle to calculate slope of a line segment. Introduce geometry link in an eActivity. Extend to length of the line …
