Ratio, Proportion, and Rates of Change I – Edexcel GCSE (1MA1)
In this course, Dr Thomas Woolley (Cardiff University) explores units, ratios, and fractions, covering Topics R1-R3 and R11 in the Pearson Edexcel GCSE (9-1) in Mathematics (1MA1) Specification for Foundation and Higher Tier. In the first mini-lecture, we introduce units and unit conversions, specifically those involving lengths (Topic R1). In the second mini-lecture, we learn how to make unit conversions for areas and volumes (Topic R1). In the third mini-lecture, we learn how to make unit conversions for mass and time (Topic R1). In the fourth mini-lecture, we introduce compound units and compound unit conversions, specifically those for speed and density (Topics R1, R11). In the fifth mini-lecture, we explore compound unit conversion for pressure (Topics R1, R11). In the sixth mini-lecture, we discuss compound unit conversions involving unit prices and rates of pay (Topics R1 and R11). In the seventh mini-lecture, we learn how to use scale factors in diagrams and maps (Topic R2). In the eight mini-lecture, we work with quantities expressed as fractions (Topic R3).
Standard Unit Conversion: Length – R1
In this mini-lecture, we begin our discussion of Topic R1 by introducing units and unit conversions, specifically those involving lengths. As we move through this mini-lecture, we consider: (i) the metric system of units (metres, grams, litres, seconds, etc.) and the imperial system of units (inches, miles, pounds, gallons, etc.); and (ii) examples that illustrate how to use conversion factors to convert between metric and imperial units of length.
