General Description

I created this course to provide teachers with a comprehensive guide to the knowledge and techniques required to teach the new NSW Mathematics Extension I syllabus. The course goes into greater detail than the textbooks, so teachers are more comfortable in their ability to deliver the content. All 140 examples have been recorded, so that you can watch an experienced maths teacher talk through the examples and any important points to note.


Part II covers Trigonometric Equations, Further Calculus and the Binomial Distribution (ME-T3, ME-C2, ME-C3 and ME-S1), three topics that bring together skills from the Year 11 and 12 courses.


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 140 recorded examples, with a 274 page course handout including 140 optional practice questions matching the examples from the course, with fully worked solutions. A suggested scope and sequence for Year 12 Advanced, Extension 1 and Extension 2 for combined classes is provided, plus a lesson by lesson breakdown of the Advanced, Extension 1 and Extension 2 courses for Year 11 and 12 to help you create your own scope and sequences.



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