Clive is doing some homework involving error in measurement and is getting a bit confused. He has made some mistakes that you need to correct and explain to him where he's gone wrong; the homework contains just stating bounds as well as calculations that require thinking more carefully about. This really makes students check their explanations and generates good academic discussion in my experience as well as allowing students to demonstrate the depth of their knowledge.

Six different "spiders" moving through rectangles, triangles, trapeziums, circles and compound shapes. These are designed to prevent students hgetting in to a rut when answering questions and to encourage discussion. Ideally used as starter or plenary but could be used as a set of questions to consolidate new learning.

A bunch of codebreakers (the usual terrible joke) having solved a load of algebra problems involving functions, arithmetic sequences, inequalities, substitution and other algebra topics. These can be used as a starter or plenary or even part of a main task in a lesson.

This takes students through simple angles properties (straight line, triangle, full turn etc) to parallel lines to angle properties of polygons and finally to circle theorems. These are not designed to fill a lesson with practice but as starters or plenaries which lead to discussion. The matchings reassure students that their answer is correct or that they may need to check their answers carefully; I have found that the "spare" question is checked far more carefully than with an exercise from a text book.

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.

There are eight matchings here: 4 surface area and 4 volume. They get increasingly difficult moving through cubes/cuboids to prisms to cones, cylinders, pyramids and spheres. These are designed to be used as starters or plenaries but you can use them for a lesson main activity, totally up to you.

This takes students through six matching activities, three on finding sides and three on finding angles. Designed to create discussion and to be used as a starter/plenary but use how you wish if you choose to download it.

I have so few resources for a lesson on 3D views that I felt I had to write one and this came to mind. The usual cheesy joke having found all the answers. Depending on the class I do this with I may allow multilink usage or I may not; you will know your class better than I.

Just the three "spiders" on bearings, of increasing difficulty. The final spider asks students if they can write the question based upon the information given which may lead to a nice discussion in class.

I have split this into two types: substitution involving rearranging and algebraic rearranging (four of each, each getting increasingly difficult). The substitution spiders are pretty straightforward but the algebraic ones should lead to discussion in class and will allow students to demonstrate (or not) that they fully understand the topic.

Four matchings - two relatively easy and two more challenging. These are designed to be used as starters or plenaries and will hopefully give students the confidence to tackle tougher problems than they usually do.

Four spiders on sets and two on shading Venn diagrams. Hopefully these will create a little discussion and make students think. A couple of the diagrams now improved.

Six matchings involving set notation and shading Venn diagrams. Hopefully these will encourage discussion in the classroom and they are designed as starters or plenaries where students, since most of the answers are there, are encouraged to try harder problems than they might normally do.

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, gradient, indices and other topics. I will be using these as starters to get students thinking.
