### Course Description

This course provides teachers with a comprehensive guide to the knowledge and techniques required to teach the new NSW Mathematics Extension I syllabus. It covers every dot point of ME-P1 Proof by Mathematical Induction and ME-V1 Introduction to Vectors. These two topics are paired with topics in Extension 2 and so need to be taught early in the Extension 1 course if students are also taking Extension 2.

The course goes into greater detail than the textbooks, so that teachers become more comfortable in their ability to deliver the content. All 101 examples have been recorded, so that you can watch an experienced maths teacher talk through the examples and any important points to note.

New and existing content is explored in detail, including interesting and more efficient techniques that experienced teachers may not have seen before. Important points to be covered with students are noted, and the limits of the syllabus are discussed. As more detail on the syllabus is released by NESA any changes required will be made. Also included are related skills that are beyond the syllabus that you can use to extend more capable students.

The course includes:

• 127 recorded examples

• 139 page course handout

• 127 optional practice questions matching the examples from the course, with fully worked solutions

The remainder of the Mathematics Extension 1 syllabus, is covered in four other courses:

EXT1#1 of the series covers  ME-A1 Working with Combinatorics and ME-F1 Further Work with Functions (F1.1: Graphical Relationships)

EXT1#2  of the series covers the remainder of ME-F1 Further Work with Functions plus ME-F2 Polynomials.

Ext1#3  covers ME-T1 Inverse Trigonometric Functions, ME-T2 Further Trigonometric Identities and ME-C1 Rates of Change

Ext1#5 covers ME-T3 Trigonometric Equations, ME-C2 Further Calculus Skills, ME-C3 Applications of Calculus and ME-S1 The Binomial Distribution.

### Audience

Mathematics teachers who are preparing to teach the new Extension 1 syllabus. This course is suitable for teachers with any level of previous experience.
