These powerpoints cover 5 lessons on the basics of Matrices, including addition/subtraction and multiplication, as well as finding the determinant and the inverse of a Matrix. I made them to go with our IGCSE book exercises so there aren't any worksheets I&'m afraid. I have also included some examples of matrices in tables and why multiplication is done in the way it is.

Pupils practice Standard Form (which they should be familiar with before this lesson is taught), and learn about many of the prefixes used. For example changing milligrams to micrograms, how big is a yottametre compared to a picometre etc. Why say 1000 kilometres when you could just say 1 Megametre? They usually find all the names of units quite interesting! If you like this resource then please have a look at my other stuff on here! :)

Based on a 10 Ticks sheet, the pupils make a magic square by substituting numbers into very simple expressions. Also explains Algebraically why it works! This could be extended into 4x4 squares for higher ability groups. If you like this resource then please check out my other stuff on here!

4 lessons taking students through processes required to understand the Mandelbrot set and fractals. Students should already know how to simplify surds and expand a double bracket. They will learn about imaginary and complex numbers, Iteration and Argand diagrams. The spreadsheet can be used to help map out points that satisfy the Mandelbrot set. Aimed at very high ability KS4 students. If you like this resource then please check out my other stuff on here! :) (and thanks to danwalker on TES for the idea for the spreadsheet!)

Lesson on calculating the Volume of Frustums, using similar shapes to work out the height of the part that has been removed. A challenging lesson for top ability GCSE pupils. If you like this resource then please check out my other stuff on here!

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!

Inspired by some UKMT questions, I made a lesson showing students how they can apply their knowledge of graphs to help with some geometry problems. Students see how placing a set of axes on a geometrical picture can help with changing the problem into an algebraic one instead. Ideally this lesson would come after doing some lessons on straight line graphs (the starter contains reminders of things they will need to be able to do to access it).

These 3 lessons are aimed at higher ability pupils who have covered linear sequences before, and need a quick recap but then an extension into harder work. Lesson 1 - Generating much more complicated sequences and finding patterns in the differences. Lesson 2 - Using the patterns they found to work out the nth term of quadratics/cubics etc. Lesson 3 - Graphing the sequences and their differences and finding links between them.

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).

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 get given 3x3 grids and must shade any number of squares so the grid has reflection symmetry. They need to try and find the total number of ways that this is possible (they hopefully will not need as many grids are as on the worksheet). It is important that they try to be logical in the way they do it!

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!

These lessons are designed to go with the IGCSE course and the CIE Extended textbook. The first shows pupils how to transform a shape by multiplying its coordinates by a Matrix, and pupils should experiment to see if they can find any specific transformations. The second lesson, pupils are shown how to work out a specific transformation. These follow on from my other resource on Matrix Algebra (also on TES). If you like this resource then please check out my other stuff! :)

Powerpoints that show pupils how to transform shapes by stretching and shearing. This was made to go with the Cambridge IGCSE course and textbook, which has plenty of questions for them to practice. If you like this resource then please check out my other stuff on here! :)

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!)

This game is good for end of term lessons. You split the class into teams (3-4 works best). You roll 3 dice for each team and they have to use the numbers however they want (including as indices or factorials) to make numbers from 1-64. Points are awarded as explained in the powerpoint. It works best if you roll the dice for all teams to start with and roll after their go, that way they can think about what number to make while you go round the other teams. It might take a bit of practice to get then hang of this but pretty much every class I've played it with loves it!

A lesson on the rules Diophantus came up with to create Pythagorean Triples. The main challenge is for higher ability pupils to prove why his method works using algebra. Weaker higher level pupils should still be able to do the numerical version though, and possibly start on the algebraic one... If you like this resource then please check out my other stuff on here!

A nice little investigation into which numbers are happy and which are unhappy. Pupils will end up with a reflected pattern in their grid and as an extension you can ask them to try and draw flow diagrams (I have referenced the source for these (davecavill - also on the TES site) in the powerpoint itself!)

Another lesson based on a worksheet I saw. Pupils investigate how many ways a coin can reach a certain destination according to a rule, then find the pattern of Pascal's Triangle. If you like this resource then please check out my other stuff on here!

I had an idea like this a while ago but recently saw it again in a magazine so I decided to put it together as a lesson in my usual way. Pupils find formulae for quadratic sequences by considering patterns of dots and their shapes, rather than the actual numbers involved. There is a second lesson here as well where they can work backwards and create patterns of dots that fit a given formula... If you like this resource then please check out my other stuff on here!
