These resources are designed to aid the teaching and learning of using a graphical method to solve linear programming problems. The first resource introduces the idea of representing inequalities on graphs and finding the point(s) that maximise a given objective function. There are also some examples that require integer solutions so the optimal point is not at a vertex of the feasible region. The second resource provides practice of solving problems with a provided graph - these are examination style questions and involve considering how changes to the objective function may change the optimal point(s). The third resource has 2 example questions in context where the students must use a description of a problem to formulate the objective function and the non-trivial constraints, and then go on to solve the problem graphically. Grids are provided for all graphs and solutions are included for all questions.

These printable worksheets make it easier to teach this topic as the questions and solutions can just be projected onto a board or screen to work through or check as a class. I normally work through the first worksheet as an example and then set the second worksheet as a task for the class to do on their own. Solutions included. Similar resources available for reflections, rotations and enlargements - please see my shop.

In a desperate attempt to make rounding more fun, here is a worksheet where each question involves rounding several values, each answer produces a letter, then these letters must be rearranged to find the title of a film. The rounding involves rounding to both decimal places and significant figures. Most films should be known by most students but this resource will need updating from time to time! Solutions are included.

This is a worksheet that is designed to be used to introduce the methods/formulae for solving arranging and choosing problems and includes exercises for the students to practise each type of problem. It includes 5 sections, one for each different type of problem. Each section has an introductory activity to work through as a class, followed by an exercise for the students to attempt. There is also a mixed exercise at the end. All answers included. This is intended for the new GCSE maths syllabus.

Powerpoint presentation designed to review the methods and formulae required to solve arranging and choosing problems. Useful to review the methods before setting an exercise or for revision of the topic. Suitable for the new GCSE maths syllabus.

A two-sided sheet of questions designed as a homework or summary task after learning how to solve problems involving arranging and choosing items. Worked solutions included. Suitable for the new GCSE maths syllabus.

The introduction sheet is designed to be used as a class activity to learn about bearings and then solving problems involving bearings using trigonometry. The second sheet is a worksheet with a mix of problems involving trigonometry and bearings (answers included).

These resources can be used as a test or a homework to assess how well your class has understood the equation of straight line graphs. The first resource is a 4-page test where students must draw graphs, find gradients or points using y=mx+c, find the equation of graphs and answer questions about parallel and perpendicular lines. The second resource is another 4-page test, similar to the first, with some slightly altered questions. The third resource contains 24 multiple-choice questions. This is a quick way of assessing knowledge and understanding and is a common style of question in the new GCSE papers. All answers are included.

The introduction activity is designed to enable students to discover the 9 circle theorem results by following instructions about what to draw and then measuring the resulting angles. The theorems should be covered in the same order as on the "9 rules" sheet which can be displayed or handed out afterwards. There are some spare circles provided at the end if students make mistakes. The group activity is a differentiated activity that tests all the circle theorems once they have been learned and practised. Instructions, answers and a scoring spreadsheet are included. The powerpoint presentation can be used as a class to practise using all the circle theorems. For each slide the class must work out the size of the missing angle and state the circle theorem used.

This is a desert-island themed activity where students must follow instructions involving bearings and using the scale of the map to find where Mr.Crusoe visits each day. All my classes have loved this activity (and have enjoyed colouring in the map afterwards!). Make sure the map is printed as A3 size or the scale will not be correct!

The powerpoint presentation can be used to introduce this topic, containing examples and explanations. The notes and examples sheet can just be handed out as a reminder during the tasks, or later as a revision resource. The first activity just requires the students to indicate on a grid whether each item is an equation, expression, identity or formula. The second activity involves cutting out each item and putting/sticking it into the correct column on the answer table. All answers are included.

This worksheet is designed to develop students' knowledge and confidence when expanding and simplifying expressions that involve two brackets. The worksheet includes questions ranging from 2(3x+4) - 5(x-3), then (x+4)(x+2), (x-3)^2, and up to (2x+1)(x-4). The solutions are fully worked solutions showing each step of the expansion and simplification.

These resources can be used to teach the topic of estimation - where the result of a calculation is estimated by rounding the value of all numbers in the calculation to 1 significant figure. The powerpoint presentation introduces the method and contains examples for the students to practise. Students can use the print-version to make notes and attempt the practice questions. The group activity is a differentiated activity that allows each group to choose the difficulty of question they attempt in each round. Instructions, answers and a scoring spreadsheet are included. The estimation worksheet contains 18 questions. The treasure hunt is a group activity which can be done at desks or can involve the class moving around the room to find the next question - usually a very popular activity! All answers are included.

The first resource is table of 34 questions where the students must find, for example, the equivalent decimal and percentage for the given fraction. This worksheet does not require knowledge of recurring decimals. The second resource is for more advanced conversion of decimals to fractions and vice-versa. It is a 4-page worksheet which focuses on converting recurring decimals, including proofs. Answers to both worksheets are included.

The test includes 21 questions with 4 possible answers to choose from. A very quick way of assessing the knowledge of your class and the accuracy of their work, in a style of question now common on the new GCSE paper. Answers included.

The presentation introduces the idea of drawing a graph to represent how quickly a container fills with liquid over time. The print-version can be given to pupils to make notes on and complete as the presentation is shown. The worksheet is designed to test their understanding after completing the presentation (answers are included).

Each worksheet has a number of examples of graphs for students to learn/practise finding information from the graph. The worksheets include estimating velocity or acceleration by drawing a tangent to the curve. All solutions are included.

This worksheet is designed to help students practise writing or understanding descriptions of graph transformations. There are 2 types of questions on the worksheet. In the first they are given the equation of the original graph and the equation of the transformed graph - they must a correct description of the transformation. In the second type they are given the equation of the original graph and the description of the transformation - they must write down the correct equation of the transformed graph. There are 20 questions of each type. All answers are included. Please note this is designed for the new GCSE spec so only covers translations and reflections.

After teaching my classes how to integrate using "reverse chain rule" and giving them enough practice to feel confident about the method, I have used this worksheet to try to encourage them to use less time and steps. My classes enjoyed the challenge of trying to complete the sheet within the time - you can always amend the time limit for weaker/stronger groups. Solutions are attached. Note that this sheet assumes that students know how to integrate the function e^x and 1/x.

This resource is designed to introduce the method for finding the volume of a shape created when an area is rotated around an axis. The first side explains the derivation of the formulae - I would recommend you also try to show your students an animation that helps them visualise a 3D shape being created by a region rotating about an axis (lots are freely available online). There are then 5 pages of questions for your students to complete. Most of the questions are in two parts - the first part involves finding an area, the second part involves finding a volume (a very common style of question in examination papers). Note that students are expected to be able to integrate using ln, e and reverse chain rule. Answers to all questions are provided.
