Yr 11 Accelerated Timeline

The timeline we will be following

For those needing a quick refresher on how to evaluate angles on the unit circle – for the HSC content simply substitute with radians

Trig_on_the_Unit_CIrcle1280by800

and a slightly different version

Trig on the Unit Circle

Lesson 1 covered solving simultaneous equations by substitution – Lesson Notes  – Solving by substitution Lesson 2 covered solving simultaneous equations by elimination – Lesson Notes – Solving by elimination

The first lesson covered radians – a measure of angle

First Lesson Notes – Radians

The second lesson covered – the special angles and radians.

Be patient it takes a while to load.

Here are some files for Year 9 Equations work

First explore the algebra balances here Algebra Balance Scales or with negative numbers here Algebra Balance Scales – Negatives

Then have a go at the soccer game

Then finally download this spreadsheet https://www.dropbox.com/s/nwjvggwypllav6b/Equations%20Step%20by%20Step%20sheet.xlsx 

and complete it (It gives you ticks when you get the steps correct)
