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 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.

These worksheets can be used to introduce and practise the new GCSE topic of equation of a circle (centred at origin) and the equation of a tangent to a circle. The first worksheet starts with an activity that helps the students to realise that x^2 + y^2 = k is the equation of a circle and is followed by some questions to practise using it. The second document is an 8-page worksheet which can be used to revise all the necessary skills/knowledge required before studying the equation of a tangent to a circle. Working through this first seemed to really help my GCSE group with this topic. Answers are included. The third document is a 9-page worksheet which focusses on finding the equation of a tangent to a given circle at a particular point or with a particular gradient. All answers are 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.

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 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.

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.

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).

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.

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.
