This PowerPoint follows the Oxford textbook. The following content is covered throughout the PowerPoint. I have also added a few extra concepts which can be used in students Internal Assessments (IA). For example, I spend a little time looking at the skewness formula, different ways of calculating outliers, 1.5 x IQR or 2 X SD, skewness in box plots, etc. Univariate data * qualitative vs quantitative * continuous vs discrete * which representations are used for specific types of data * primary and secondary data * choosing a good sample * sampling bias * reliability vs validity * skewness Questionnaires * biased questions Measures of central tendency * mean, meadian, mode * outliers * un-grouped and grouped * how to use the GDC * combined mean Measures of dispersion * range, quartiles, IQR, standard deviation * normal distribution curve * skewness * different formulas for sample and population for SD * how to use the GDC * effects on mean and SD Sampling techniques Presentation of data Bivariate data * scatter graphs * correlation * introduction into the line of best fit (leading into chapter 6) Throughout the PowerPoint there are worked examples and student exercises. There are also multiple links to various classroom and interactive activities using GeoGebra and Desmos Classrooms. As well, I have included links to certain Youtube videos to help with using the GDC.

This PowerPoint follows the entire content for Chapter 1 of the Oxford textbook. Certain topics included are not in chapter 1 but builds on the skills students are currently learning in the chapter and will be useful later on. For example, for the simplifying indices topic I go a little further into writing indices in non-fractional form which is useful for when you teach derivatives. Conent covered through the PowerPoint include: Measurements and Estimates Rounding and Significant Figures Upper and Lower Bounds Measurement Error Percentage Error Basic Exponent Rules * changing bases * writing in non-fractional form Standard form (scientific notation) Right angle trigonometry * Pythagoras * proving right angle triangles * algebraic problems * SOH-CAH-TOA * elevation and depression * problems involving circles * 3D problems * problems involving special quadrilaterals * angles between lines and planes Arc Length Throughout the PowerPoint you will find GeoGebra links (click the icon) as well as Past Paper questions.

Here is a short independent task looking at time series of population over time. It also creates discussion for curves of best fit.

I used this lesson before going into the quadratic formula and the discriminant.

For those higher achieving students looking to get a grade 9. As proofs is new to the Edexcel specification, digit proofs is not common but has shown up on a Mock Exam.
