#### Mean - full lesson

A lesson made for high ability year 7 but suitable for any class to introduce mean.
Starter is a revision starter which should be changed to suit your class
Discussion slides - what do they know already, why do we add and divide to find the mean.
A mixture of questions (integers, decimals, negatives)
When is mean not useful? Discussion points / questions which show when the mean is misleading i.e when outliers skew the data
Any comments/ feedback would be greatly appreciated.

#### Introduction to Trigonometry (2 lessons)

2 lessons introducing trigonometry. Previously when teaching trigonometry to lower ability classes I focused on the steps but not why they are used. With these lessons the pace is slower but it really goes into what Sine is and where the steps come from.
Lesson 1 - Finding missing lengths using Sine
Spotting patterns in right angled triangles with the same angles e.g when the angle is 30 the opposite is half the hypotenuse
Using tables to find missing lengths
Using the Sine button on the calculator to find missing lengths
Practice (questions taken from CorbettMaths)
Lesson 2 - Finding missing angles using Sine
-Recap from previous lesson
Finding missing angle (begins revisiting the table but moves quickly into calculator)
Trigonometry practice questions with answers (this has a mix of length and angle questions and a sneaky Pythagoras question to check they can spot when to use which skill). Questions taken from CorbettMaths and MathsGenie
Exact Values (Sine)
This was a complete new approach to introducing trigonometry for me to any feedback would be greatly appreciated

#### Averages

Averages lesson initially used with high ability KS3
-Key skills starter suitable for the class

#### Recurring Decimals

A whole lesson, used with high ability Year 9 and 10, on converting recurring decimals into fractions. It also includes how to tell if a fraction will recur.
Starter is a mixed starter covering recent topics we had covered (adapt to suit your class)
Recap converting fractions to decimal
Activity moving fractions into relevant columns, terminating or recurring. Some of these the students knew, some they could work out. As they went they were looking to see if they could spot a pattern to help them. We then discussed and they copied down the rule.
Converting simple recurring decimals to fractions (examples and exercise)
Converting more complicated decimals to fractions (examples and exercise)
Any feedback would be greatly appreciated
