Students see how geometric sequences can be used to calculate distances on a guitar fretboard. There are several questions to discuss, and a lot of nice uses of formulae. Should also give them a nice practical example that isn't of the type often found in textbooks! If you like this resource then please check out my other stuff on TES (all free of course!)

Based on Dan Walker's resource I saw a while ago (https://www.tes.com/teaching-resource/san-gaku-6384597), I then made a set of Sangaku Problems - great to use in the build up to the UKMT challenges!

Pupils have to use types of numbers (square/triangular etc) and their properties (even/odd/factors etc) in order to solve problems. The two puzzles used in the activity are not my own (I'm not sure where I originally found them...), but are excellent for pupils to discuss how to approach problems. If you like this resource then please check out my other stuff on TES! :)

Tiles are put together to make a larger rectangle. The question is: If we draw a diagonal from one corner to the other, how many tiles will it cross? The pupils should investigate and see if they can find a rule. If you like this resource then please check out my other stuff on here!

Pupils have to split shapes into congruent pairs by drawing lines on them. Makes teaching congruency more interesting and there is an extension activity for more investigation. You will need to write on some of the powerpoint slides! Thanks to Jim Noble (@teachmaths, http://www.teachmathematics.net/) for the idea!

Improved version of an older resource of mine. Pupils are shown some simple graphs (horizontal, vertical, and diagonals based on y = x and y = -x), and have to try and use these graphs to create shapes. It is essential that pupils always label their lines and for the plenaries they can share some of their answers on the board.

As with my other resources for A-level, these are made to go with the Edexcel course and textbooks, and cover the whole of C1. The worksheets are a good starting point for exam preparation as they split the course up - better than sending them straight onto papers with all different topics on! If you like this then please check out my other resources on TES! :)\nEDIT: 7/6/14 Added Mark Schemes to the worksheets!\nEDIT: 28/11/14 Added chapter 1-3 tests to use as evidence of suitability for the rest of the A-level course!

This is an eight lesson sequence designed to review fractions and percentages work, and lead onto using ratio in problem solving. Every lesson has a starter, explanation and plenary in a powerpoint, along with a worksheet with a variety of difficulty of questions (some taken from the UK Maths challenges), all with answers. It is a part of a much bigger library of resources that can be found here: https://www.tes.com/teaching-resource/maths-free-resource-library-6439409 If you liked this resource then please check out my other things on the TES site!

3 Lessons of Powerpoints and Worksheets covering the areas of Rectangles, Triangles, Parallelograms and Trapeziums. The pupils have to find areas of different colours on national flags which are all the above area, and also using other mathematical topics. You will need to write on the powerpoints quite a bit on the starters, plenaries and examples! If you like this resource then please check out my other stuff on here!

This set of powerpoints go with the Edexcel textbooks and cover the entire Core 4 course from start to finish. Pupils can use these for revision or you can use them to deliver lessons! The worksheets can be used as end of chapter tests or as a basis for starting revision. If you like this resource then please check out my other stuff on here! :)\nEDIT 9/6/14: Added Mark Schemes to the worksheets!

Pupils get shown several shapes which are to be represented by letters. They then have to state the areas of some compound shapes algebraically, which are made up of the original ones. If you like this resource then please check out my other stuff on here! :)

Pupils create equations from worded scenarios. The Powerpoint has a number of examples to use which you will need to write on, as well as a starter, plenary and worksheet with answers! :) If you like this resource then please check out my other stuff on here!

Pupils learn to calculate the volume and surface area of spheres using the relevant formulae. There is a selection of harder questions to challenge the more able on the sheet. In the powerpoint is a link to a demonstration of the formula (not involving calculus as students studying this topic most likely will not have encountered this yet!). The video is NOT my own work - credit goes to mathematicsonline for that! If you liked this resource then please check out my other stuff on here! :)

This lesson is intended as an introduction to Tree diagrams. In it, pupils see how Tree diagrams can be used to show different combinations of events, and can therefore be used to calculate probabilities. There are no probabilities on the diagrams at this point, this idea can be introduced at a later date. The worksheet has a variety of questions, with answers included.

Ready-to-go lesson on calculating the mean from a table. With weaker groups it is very important to explain exactly what the numbers in a table represent first! If you like this resource then please check out my other stuff on here!

Pupils are shown how to plot straight line graphs by finding coordinates. Also includes a possible application in videogames (It probably does not work exactly as shown, but it can still show the topic as 'useful'!) If you like this resource then please check out my other stuff on here!

Pupils become familiar with the f(x) notation and what some of the transformations actually mean in terms of the function itself. They then change a function based on the transformation and plot the corresponding values so they can see its effect. There is most likely several lessons of work here and it is broken into separate sections. If you like this resource then please check out my other stuff on here! :)

Pupils have to use the heights of one building to estimate the heights of others, and produce sketches of several well known buildings to scale. If you like this resource then please check out my other stuff on here!

Pupils plot coordinates based on rules. This is effectively graph plotting but without using the formal algebra. The powerpoint is set up in such a way that certain sections should be written on and the worksheet has plenty of questions! If you like this resource then please check out my other stuff on here! :)\nEDIT: 1/4/14 Improved the visibility of the gridlines on the sheet.

These 2 Powerpoints have been made to go with the Oxford CIE IGCSE extended textbook, but could probably be adapted quite easily. It is basically introductory lessons on plotting, spotting the general shape of, and using Cubic graphs. Prerequisite knowledge is that of plotting graphs generally (including Quadratics).
