Proof (new A level) - worksheet to teach & practise the whole topic + 3 homeworks/tests

Proof (new A level) - worksheet to teach & practise the whole topic + 3 homeworks/tests

This 10-page worksheet can be used to teach the whole topic of proof in the new A level specification for all exam boards. A great resource to help deliver this new topic - fully worked solutions included and a version with teaching notes added for some key points. It begins by reviewing all the required basic knowledge with some examples to work through, discusses particular errors in solutions/proofs, covers the use of ⇒, ⇐ and ⇔, interval and set notation, and then looks at the different methods of proving/disproving propositions. For each of the 4 methods (counter example, deduction, exhaustion and contradiction) there are a number of examples for you to work through as a class or get the students to attempt. I needed 4 hours of teaching time to get through this whole worksheet with my classes. There are also some suggested extension activities for students interested in doing some research that goes beyond the scope of the syllabus. Note that I designed this resource to work with a particular textbook accredited for the AQA course, so the references to exercises and page numbers may need to be amended for the exam board and textbook you are working from. 3 different homeworks/tests are also included, with fully-worked solutions provided.

Resolving forces - worksheet to teach and practise this skill (Mechanics 1)

Resolving forces - worksheet to teach and practise this skill (Mechanics 1)

I found it time-consuming tryingto teach my classes how to resolve forces by drawing diagrams on the board and asking them to copy them down - it seemed to take ages and they didn't get to work through that many examples themselves. So I created this worksheet with ready-made diagrams with all the forces and a blank copy of diagram for students to add on the resolved forces. I no longer dread teaching this skill and my classes get a lot more done in the lesson time. The worksheet starts with an introductory explanation and a worked example. There are then over 20 questions for students to attempt. Fully worked solutions are included.

de Moivre's theorem and roots of polynomials - teaching notes and examples

This worksheet can be used to introduce de Moivre's theorem to your class and show how it can be used to find multiple angle formulae (e.g. sin 4theta = ...) and how these formulae help us to relate trigonometric equations to polynomial equations.

Graph transformations resources (new A level)

Graph transformations resources (new A level)

This set of resources includes everything you need to teach the graph transformations topic in the new A level. The printable resources will save you and your classes a lot of time which means there is more lesson time for them to practise and for you help develop their understanding. As the topic requires knowledge of the properties of some graphs (e.g. asymptotes) the first resource can be used to see which graphs they can already sketch and to discuss the asymptotes of particular graphs. The next resources are Geogebra files which can be used with the free Geogebra software. Each file can be used to discuss a particular type of graph transformation - there are sliders on each file that be changed or animated to see the initial graph transformed. This activity should help your class to visualise each type of transformation and start to get a feel for how the equation changes. The notes and examples start with revising each type of graph transformation - giving some different ways the transformations can be described and what the transformation looks like using y=f(x) and with a particular curve. Once completed this is a useful revision resource and helps them complete the exercise of questions on the reverse which includes questions asking for the new equation of a transformed graph, or for a description of the transformation applied. The final resource can be used to give your class practice of sketching transformations of y=f(x). The answers to all questions are included, including the sketches.

Finding roots and real factors of z^n+k=0

Finding roots and real factors of z^n+k=0

The first resource guides your class through the process of using the real and complex roots of z^n+k=0 to write down its real factors. The introduction includes the important result about the sum of conjugates and then uses equations of the form z^n=1 or z^n=-1 to establish that there is always an even number of complex roots, which can be put into conjugate pairs. It is then shown how each conjugate pair of roots produces a real quadratic factor, while each real root produces a real linear factor. To practise all this there is an exercise with 7 questions for students to complete. Solutions to all the examples and the exercise are included. The second resource contains an exercise with further examination-style questions on this topic. This could be used as additional practice in class or as a homework/test. Answers are provided.

Simplex algorithm worksheet and solver (Decision maths)

Simplex algorithm worksheet and solver (Decision maths)

The first resource guides your students through the whole process of using the Simplex algorithm to solve a linear programming problem. The first page explains how the initial tableau is formed, how the objective function must be written and how the inequalities that represent constraints must be written as equations with the introduction of slack variables. The first exercise (11 questions) gives them the opportunity to practise writing the initial tableau correctly for different problems. Grids are provided so students focus their time and energy on only the values in the tableau. The next section describes how an iteration of the algorithm is performed and links the iterations to the graphical solution, showing how each iteration moves to a different vertex of the feasible region. There is then another exercise with 10 questions for students to practise performing iterations and finding the optimal solution. Again, grids are provided so students focus their time and energy on only the steps of the algorithm and the values in the tableau. Fully worked solutions are provided to all the questions in the exercises. The second resource is a spreadsheet that automatically solves any simplex tableau in 2/3 variables with 2/3 constraints - a useful resource for doing/checking solutions to other questions from a textbook or examination paper.
