This is a free, three slide preview of my full PowerPoint presentation for “Elastic Collisions in Two Dimensions”. This preview is an editable PowerPoint presentation containing an example of two spheres colliding, and concludes with an animation of the collision. The full 19 slide presentation covers the content required for the A-Level mathematics topic “Elastic Collisions in Two Dimensions”. I developed it in order to teach the topic to my students. The content is based on the Edexcel FM1 specification, and chapter 5 of the Edexcel FM1 textbook. I have used PowerPoint’s animation effects extensively. All slides use the “appear” animation to build up the content in a clear, meaningful manner. I also used the “zoom”, “free motion” and “fade” animations to bring the material to life for my students. I have included extensive teacher notes with each slide. The slides contain all the required theory, and detailed, worked examples for each of the three sections: Oblique Impacts with a Fixed Surface Successive Oblique Impacts Oblique Impacts of Smooth Spheres Most examples are either fully original or extensively adapted/ modified from examples within the Edexcel textbook. I hope you find the PowerPoint presentation useful in your teaching practice. Please feel free to contact me if you have any feedback. Regards Gerard

Chi-Squared Tests for Goodness of Fit This is a free preview PowerPoint slideshow, containing approximately half the slides, is also available. The full, 58 slide PowerPoint presentation covers the content of “Chi-squared Tests” within Edexcel Further Statistics 1 (Chapter 6 of the official Pearson FS1 textbook). Each slide is accompanied by teacher notes. We start with a general introduction for how you quantity the closeness of observed frequencies to the frequencies expected for a chosen standard distribution i.e. how to calculate Pearson’s Cumulative Test Statistic, X^2. Both methods of calculating X^2 are covered. In order to properly understand the concept of “Degrees of Freedom”, additional examples are included to fully explain how we determine the degrees of freedom of a given dataset by taking into account restrictions placed upon it. In my opinion, this is handled poorly by the textbook. The loss of degrees of freedom due to having to combine adjacent columns of the dataset (because the observed/expected frequencies are too low), and because the observed data itself is needed to calculated a required parameter of the model distribution is also covered. We then link this to our existing knowledge of Hypothesis Tests, and introduce the Chi-squared family of distribution. This section has also been extended to ensure that students properly understand how the chi-squared graphs vary with the data’s degrees of freedom, ν, and how to effectively these graphs (either by using the table “Percentage Points of the Chi-Squared Distribution” in the formula book or by using a calculator e.g. the Casio CG50). Once we have the foundations in place, we use them to work through exam-style examples, comparing the given observed data to a chosen standard model distribution. For each example, we perform a hypothesis test to determine if there is sufficient evidence, at the required significance level, to reject null hypothesis. The examples cover the following standard distributions: Discrete Uniform Distribution Geometric Distribution Binomial Distribution Poisson Distribution All examples are either newly created or significantly modified from past paper questions. For each standard distribution we explain how to determine the probability of each outcome and, hence, the expected frequencies. We also explain how to, if necessary, estimate a required parameter (e.g. ρ for the Binomial distribution, λ for the Poisson Distribution) from the observed data. The presentation, unlike the textbook, deals with the four standard, discrete distributions in turn i.e. it does not delay the section on the Geometric Distribution until the end. Instead, the section on continency tables is left to the end and given its proper title of “The Chi-Squared Test of Independence”. In addition, the presentation contains detailed examples showing how to use the Casio CG50 calculator to perform Chi-Squared tests. Regards Gerard

This free sample PowerPoint SlideShow is an extract from my 40 slide PowerPoint presentation that fully explains the ideas behind the Two-Stage Simplex Algorithm, and gives clear, animated, step-by-step examples showing how to use it. Extensive use has been made of PowerPoint’s animation features. Slack, surplus and artificial variables are explained, as is the creation of the additional objective function i.e. A = “The total of the artificial variables”. The slides can be used as the basis for teaching the topic to a A-Level mathematics class. They provide enough, clearly explained details to also act as a useful revision/self-study aid. I hope you find this resource useful within your teaching practice. Regards and best wishes, Gerard

This is a 24 slide free, sample preview of my 50 slide PowerPoint presentation covering all the content of Chapter 5 of Edexcel’s A-Level book “Decision Mathematics 1” (2017+ specification). This includes: Minimum Spanning Tree (Upper Bound) Looking for Shortcuts Residual Minimum Spanning Tree (Lower Bound) Nearest Neighbour (Upper Bound) The slide set makes extensive use of PowerPoint animations to clearly explain the involved algorithms. I have provided teacher notes, where necessary, for each slide. I have also used an extended practical example throughout the presentation relating to band’s (XTC) actual, short tour of the UK in 1979. The intent is to emphasis that the algorithm has practical uses in the real world. Necessary terminology is revised, as is Kruskal’s and Prim’s algorithm’s for finding a Minimum Spanning Tree (MST). I hope you find the PowerPoint presentation useful within your teaching. Regards Gerard

This is a free preview PowerPoint Slideshow that contains approximately half the slides in the full slide set. I have always found it difficult to get across the concepts required to support Linear Programming to my weaker Higher GCSE groups and especially, more recently, my Core Mathematics groups. There are several issues preventing the less confident mathematicians from doing well in this topic. Firstly, many students are not even confident about plotting simply straight lines such as x = 3, y = 7, x = y etc. Secondly, a lot of them have not fully understood the concept of an inequality. Thirdly, in general these students find it very difficult to convert an English sentences into mathematical statement. I have put together this 90+ PowerPoint slide set to address these problems. I have created interesting/funny ways to remember that x = 3 is a vertical line, whilst y = 3 is horizontal. I have included practice on plotting straight lines and shading regions represented by inequalities. I also introduce the idea of a “test point” that will allow stidents to work out which side of the line they require. I have included practice on solving simultaneous equations using a Casio fx-991EX CLASSWIZ calcuator, and also by manulally solving the equations. A video of how to use the Casio 991 to solve simultaneous equations in included. Of course, the idea of an Objective Function covered, together with how to use the feasibility region to locate the required minimum/maximum value. I focus the students on investigating points close to or at the vertices of the feasibility region. I have stayed away from moving an example objective line through the feasibility region to see which is the last vertex it goes through. This proved a bridge too far for too many of my students! The slide set includes a lot of worked examples, and practice questions along with their solutions. I hope you find the presentation useful. Please let me know if you find any typos or if you have a suggestion as to how it can be improved. Regards Gerard

This is a 16 slide, free preview of my 34 slide PowerPoint presentation covering Edexcel FS1 Chapter 7 “Probability Generating Functions”. This preview shows you the details contained within the slides, and the presentation style. I have included new examples and proofs of the results covered within the topic. The full slide set also comes with my solutions to all the questions of every exercise (including the “Challenges”) within the chapter. (I do the questions independently from any published solutions, so you might find I have arrived at the same answer in a different way, showing detailed working along the way.) I am happy to receive any feedback you might have for further improvements to the presentation. Regards Gerard

This is a 4 slide preview of my full, 24 slide, PowerPoint presentation covering the relationship between the roots of quadratic, cubic and quartic polynomials and their coefficients. These relationships are derived algebraically, and worked examples are provided explaining typical A-level questions. Teacher’s notes are included with each slide. The full presentation is perfect for teaching this Further Mathematics Core Pure topic. Slides are included to remind students of how the graph of the polynomial is related to the number of real roots, including repeated roots. The standard results for the “sum of reciprocals”, “sums of squares” and “sum of cubes” of the roots of quadratics, cubics and quartics are derived and used. The presentation finishes with applying the newly learned knowledge to graph transformations. I have kept the presentation style as simple as possible, using the “appear” animation extensively to build up each slide. I have also included teacher’s notes for each slide. In summary, the full PowerPoint presentation provides everything you need to teacher this A-level Further Mathematics topic. I hope you find this resource useful within your teaching practice. I would be very happy to receive any feedback you might have. Regards and best wishes, Gerard
