This is a matching activity on bounds (it does what it says on the tin?), including the potential error in calculations. Ideal for a starter or plenary and should hopefully generate discussion and enable students to demonstrate understanding.

Eight matching activities, getting increasingly difficult, on various different formulae to rearrange. These are designed as plenaries or starters and should encourage discussion.

There are four "explosions" for students to deal with, each covering different types of algebraic fraction. The first slide involves simple indices and simplifying, the second involves adding and subtracting (find a common denominator), the third has algebraic expressions as denominators and the fourth involves factorising quadratics. These are designed to stop students getting in a rut of doing the same thing over and over again, plus they should (hopefully!) generate good mathematical discussions.

This is a set of 6 sheets of increasingly difficult simultaneous equations designed to make students think and discuss how to work through their solutions by giving them different parts of the process. They include simultaneous equations that involve a linear and a non-linear equation. This is also designed to stretch at GCSE or could be used at the start of A level.

Four matchings getting increasingly difficult at they go Firstly spot the correct formula for the correct triangle, the next two calculate a missing side and finally use Pythagoras to find the area of a shape. These have been designed to be used as starters or plenaries but you could use them as a main lesson activity; up to you.

This takes students through basic shapes (rectangles and triangles) to trapeziums and parallelograms and finally circles, including compound shapes. I use these as starters or plenaries but use them how you like.

A set of six spiders which encourage students to show every stage of their calculations as they tackle increasingly difficult questions. There are also some question where the answer is given and the workings shown so that students can work backwards; this is designed to avoid students getting stuck in a rut and not thinking about what they are doing in each case.

This idea is from Craig Barton and is an excellent one (check them out his at website); essentially it is four questions based on the same information. There are four here which use fractions, ratio, percentages and averages as well as other topics. This really should create discussion and a deeper understanding of the topics covered on top of ensuring that students actually read the question. I hope these are worthy! I will be using these as starters or plenaries. I haven’t used logos to avoid any copyright issues. Hyperlinks added…

This is designed to get students thinking rather than just blindly following a mathematical recipe. There a four sets of 4 problems which all have the same answer (given in the centre of the screen). Each question has a blank for the students to fill in and sometimes there is more than one answer for the blank. This particular one covers probability, percentages, fractions, ratio, angles, equations, equations of lines and other topics. I will be using these as starters to get students thinking from the off and will produce more if they work!

I had this idea whilst driving home tonight thinking that I could do with some more stuff on bearings. The idea is for student to practice all the skills involved in bearings problems (angle properties on lines, around a point, triangles and parallel lines as well as scale) and then move on to solving some actual bearing problems. I have designed it in the shape of a wall to show that we build up to the summit. Obviously with this topic, scale is more of an issue but I hope it’s useful… (error corrected)

I have concentrated on the algebra rather than linking to graphs of functions as I’m not sure at GCSE that the graphs are overly helpful for solving function notation problems; I will eventually get on to transforming functions which will tackle this (size could be an issue in the format though). This goes from simple function machines, through substitution, rearranging formulae and links them to functions questions. This started off as a request from a former colleague who bemoaned the lack of function notation resources, which is a fair point at present, I think.

This takes students through the skills required to answer vectors questions and some vectors questions from adding vectors to describing routes to proof.

This details the skills required to perform GCSE proofs up to grade 8/9 building up from the basics to the more complicated questions.

This covers from simple finding pairs of integers up to completing the square, including completing the square and the quadratic formula. I will put solving graphically on a another one as there wasn’t room here.

All the skills required for sequences up to and including summing arithmetic sequences and geometric sequences.

This takes students from fairly straightforward area and perimeter questions (trapeziums, circles etc) through compound shapes and on to cones, frustums and hemispheres including finding the height in terms of the radius for a cone. I have tried to cover all bases with it including density and capacity problems.

This (hopefully) covers circle theorems from basic up to one proof questions using circle theorems. There should be enough variety to cover all bases.

Working up from simple fraction of a number to adding/subtracting/multiplying/dividing mixed numbers with everything in between, including a “Show that” question which always seems to confuse some.

Working its way up from symmetry to negative and fractional scale factor enlargements; the diagrams are as big as I can make them in the format so sorry if they are a bit small.

This leads students through basic angle facts through parallel lines, polygons and then onto forming and solving equations or writing angles using algebra.
