#### Where was the free kick taken from? - Photos, football and algebraic fractions

Inspired by a Numberphile video where they use still images to calculate the position of a footballer taking a free kick (https://www.youtube.com/watch?v=ffvojZONF_A) Resource is aimed at GCSE groups (higher) and will need at least an hour. Students are given four photographs and instructions that allow them to calculate where each player was standing when they took the free kick by measuring distances on the photographs and computing cross-ratios. They then have to solve a simple algebraic fraction equation to work out the unknown distance. Included: presentation to help explain the tasks, worksheet with photographs and an additional sheet that scaffolds the process if needed, set of exemplar answers. Students can draw any straight line they like from the ball to the goal so they will have different distances in their cross ratio but should end up with the same final answers. Potentially leads to discussion opportunities about how the cross-ratio changes with the players position and even an introduction to limits as you consider what happens if the player is very close to or very far away from the penalty area. *Presentation edited to include extension tasks incorporating using trig to find the kick angle and problem solving to work out the location of a different player and flight path of a pass followed by a shot **Answers updated to include challenge 1 and 2

#### Trigonometry test x2

This is a sample from a collection of short tests on trigonometry in right-angled triangles. All the tests are quite short (3/4 questions, so 5-10mins max). I created them so that I was able to test my classes more regularly on topics at different points through the year - each test is similar enough so that classes hopefully improve at the “standard” questions but there is also some variety in the later questions in each test and a progression in difficulty as you go through the tests. There are 10 tests designed to be done with a calculator, 10 tests to be done without a calculator. The questions include: 1.Finding an angle or a side of a right-angled triangle 2.Stating the correct value of e.g. sin A for a given triangle (requires Pythagoras) 3.Knowing and using exact values of trig functions 4.Using trigonometry in isosceles triangles 5.Using trigonometry in 3D shapes 6.Using trigonometry where side lengths are given as surds 7.Proving identities/results with trig functions 8.Questions with bearings, angle of elevation/depression All tests come with fully-worked solutions which makes them easy to mark. This means that the tests could also be used as a revision resource for students. The full set of tests are available here: https://www.tes.com/teaching-resource/trigonometry-tests-x20-11931966

#### Area of a triangle trigonometry version

A complete lesson on the 1/2 absinC area rule. Doesn’t include ‘reverse’ problems (I’ve made a separate resource on this). Activities included: Starter: A set of questions on area of triangles using bh/2. Main: An area question for pupils to attempt, given two sides and the angle between them. If they spot that they can use SOH to get the perpendicular height, they have effectively ‘discovered’ the 1/2absinC rule. If they don’t spot it, then the rule can be easily explained at this point. A set of questions designed to be done as a class using mini whiteboards, progressing from identifying the correct information needed to calculate area, to standard questions, to trickier questions (see cover slide for an example). A two-page worksheet (I’d shrink and print as one page) with a similar progression in difficulty, for pupils to consolidate. Includes a suggested extension task in the comments box of the powerpoint. Plenary: A closer look at question one from the worksheet, which links to the graph of sine.

#### Flashcards for GCSE/IGCSE Mathematics (Formula)

Memorizing formulae has never been a fun thing to do. That is exactly why these flashcards have been designed. This folder consists of three sets of flashcards, with formulae that GCSE/IGCSE students are expected to learn (Quadratic Formula, Pythagoras’ Theorem, Sine Rule, Cosine Rule, and Area of a triangle). This activity can either be done in pairs or small groups and is apt for revision. Simply spare 10 minutes of your lesson for this activity, and your students would have memorized these nauseating formulae before they even realize it!!! GCSE formula sheeet/ IGCSE formula sheet/ Cambridge 4024/ GCSE 9-1 mathematics

#### Pythagoras and Trigonometry and how to spot the difference!

#### Inquiry: Can't Pick's an Equilateral Triangle.

A 15-minute Mathematical Inquiry Assessment Item for Junior and Middle Secondary.

#### Triangle area activity

A challenging activity on the theme of triangle area, suitable for year 11 revision. The initial questions require a knowledge of basic triangle area, Pythagoras’ theorem, SOHCAHTOA, the sine rule and 1/2absinC so a good, challenging revision task. The questions have been designed with a ‘minimally diferent’ element, to draw pupils attention to how subtle changes can have significant implications for selecting methods. There are some follow-up questions, that could be used to shift the focus of the activity. I’d love to hear anyone’s suggestions of further questions.

#### Cosine rule to find sides

A complete lesson on using the cosine rule to find a missing side of a triangle. Activities included: Starter: A prompt for pupils to do an SAS triangle construction, in order to measure the third side. This leads to you revealing the ‘exact’ answer and hopefully pupils wanting to know how you did it… Main: Slides and diagnostic questions to make sure pupils can use the relevant labelling system for triangles, when using the cosine rule. Slides to introduce the cosine rule. I haven’t included a derivation at this stage, as it’s pretty tough. I’ve included this later, and it could be used with the right class to extend them. Example problem pairs for pupils to try, followed by a two-part worksheet for pupils to practice. The first part has straight forward questions, the second has more varied and challenging questions. I’ve thrown in a bonus challenge question that leads to a quadratic equation. Plenary: A prompt for pupils to consider how the cosine rule connects to Pythagoras’ theorem. Printable worksheets and answers included. Please review if you buy as any feedback is appreciated!

#### Sine rule problem problem solving

A complete lesson of more challenging problems involving the sine rule. Designed to come after pupils have spent time on basic questions. Activities included: Starter: A set of six questions, each giving different combinations of angles and sides. Pupils have to decide which questions can be done with the sine rule. In fact they all can, the point being that questions aren’t always presented in the basic ‘opposite pairs’ format. Pupils can then answer these questions, to check they can correctly apply the sine rule. Main: A set of eight more challenging questions that pupils could work on in pairs. Each one is unique, with no examples offered, and therefore I’d class this as a problem solving lesson - pupils may need to adopt a general approach of working out what they can at first, and seeing where this takes them. Questions also require knowledge from other topics including angle rules, shape properties, bearings, and the sine graph. I’ve provided full worked answers FYI, but I would get pupils discussing answers and presenting to the class. Plenary: A prompt for pupils to reflect on possible rounding errors. Most of the questions have several steps, so it is worth getting pupils to think about how to avoid rounding errors. I’ve left each question as a full slide, but I’d print them 4-on-1 and 2-sided, so that you’d only need to print one worksheet per pair. Please review if you buy as any feedback is appreciated!

#### Sine rule ambiguous case

A complete lesson on the scenario of using the sine rule to find an obtuse angle in a triangle. Given the connection this has with triangle congruence and the graph of sine, these ideas are also explored in the lesson. Designed to come after pupils have spent time doing basic sine rule questions and have also encountered the graph of sine beyond 90 degrees. Activities included: Starter: A goal-free question to get pupils thinking, that should help recap the sine rule and set the scene for the rest of the lesson. Main: A prompt for pupils to construct a triangle given SSA, then a closer look at both possible answers. Depending on the class, this could be a good chance to talk about SSA being an insufficient condition for congruence. A related question on finding an unknown angle using the sine rule. Pupils know there are two answers (having seen the construction), but can they work out both answers? This leads into a closer look at the symmetry property of the sine graph, and some quick questions on this theme for pupils to try. Then back to the previous question, to find the second answer. This is followed by four similar questions for pupils to practice (finding an obtuse angle using the sine rule) Two extension questions. Plenary: A slide to summarise the lesson as simply as possible. Answers and printable worksheets included. Please review if you buy as any feedback is appreciated!

#### The sine rule

A complete lesson on the sine rule, looking at standard questions involving two pairs of angles and their opposite angles in a triangle. See my other resources for lessons on the ambiguous case and on more challenging questions involving the sine rule. I have also made an ‘introduction to the sine rule’ lesson, designed to precede this one, but this lesson also works as a stand-alone. Activities included: Starter: A number puzzle that leads into rearrangements of the equation ab=cd (relevant to rearranging the sine rule). Main: A very quick derivation of the sine rule by splitting triangle into two right-angled triangles. A slide showing some ways of rearranging the rule. The intention is that pupils describe how each rearrangement has been obtained from the initial form of the rule. A good way of consolidating changing the subject. Example problem pairs for pupils to try, on finding sides and angles, and a set of six similar questions to consolidate. A suggested follow-up task for pupils to produce a poster with the key ideas - the derivation of the rule, rearrangements of it and some examples that pupils could create themselves. Plenary: A slide showing the full rule a/sinA=b/sinB=c/sinC (up till then I have only shown a/sinA=b/sinB), to stimulate some discussion and provide a possible extension task of pupils proving the full version. Answers included and no printing required.

#### Introduction to the sine rule

A complete lesson for first introducing the sine rule, although it includes some related questions on constructions. Focuses more on a derivation of the rule than exam-style questions (see my other resources for lessons like that). Assumes pupils have already learnt SOHCAHTOA. Activities included: Starter: Four recap questions involving the sine ratio and right-angled triangles. Main: Slides and quick questions to familiarise pupils with the labelling system used for the sine rule. A prompt (see cover slide) to derive the sine rule using prior knowledge, followed by a series of related questions. These move from pupils simply substituting letters and numbers into the sine rule to using the rule to find missing sides and angles. I haven’t followed this up with a worksheet of similar questions (this will come in a future lesson), as the intention at this stage is mostly on getting pupils substituting the correct information. A prompt for pupils to attempt an SSA construction using ruler and protractor. The construction is impossible and nicely connects to the sine rule and the graph of sine. This is followed up by a challenging task where pupils investigate making changes to the information given for the construction, so that it is possible to construct the triangle. Plenary: A final prompt for pupils to think about the sine rule dynamically (considering what happens as one point of a triangle is moved) Answers included throughout, no printing needed. Please review if you buy as any feedback is appreciated!
