Three questionnaires to correct and design hopefully covering the majority of things that can go wrong. This has no "bells" or "whistles" but just asks the questions I want it to.

Determine what power x is in each case and link it to the correct answer.

Erica is struggling with 3D vectors here, including unit vectors, magnitudes and areas of triangles. Designed for the new A level syllabus it doesn't get as "difficult" as they did in Core 4 but this should allow students to demonstrate their understanding.

The next in the “Building Blocks” series going through all the skills that lead up to different ratio problems. I have included simplifying fractions, unit conversion, HCF before moving on to ratio problems of varying difficulty levels. Hopefully this should provide some useful revision tasks.

Another one of these, taking students through the skills required for linear graphs up to and including perpendicular line.

Erica has started calculus but is struggling yet again. Please help correct her work and explain what she has done wrong in each case. Designed to promote discussion in the classroom.

Two “Crack The Safe” activities on rounding, estimation and bounds; the first one is simple decimal places and significant figures and the second involves bounds. These contain six questions but ten possible answers meaning that students can self-check their answers (are they in the list of possible answers?) whilst the teacher can help those who require it. I use these as starters and plenaries but that is obviously up to you.

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

Charles Xavier has asked Wolverine to run an angles course this term but Wolverine's angle knowledge is a little rusty. Can you answer the questions and explain to Wolverine which angle property you've used? Contains the following: on a line, around a point, in a triangle, in a quadrilateral, parallel lines

The elves have packed the sleigh with two sacks before checking the weight of each present! There isn't time to unpack the presents to weigh the presents individually, so can you use your knowledge of algebra to help?

Five slides each with five questions that students must decide whether the given answers are correct or not, explaining their reasoning. There are questions on equivalence, fraction/percentage of an amount, calculations, percentage change etc. These are designed to create discussion in class.

Here are some simple average questions from sets of data, plus one question using a frequency table too, all on one sheet.

The 1D boys are describing what it's like to be a pop star but using all the wrong units of measurement; the measurements are correct, but the units need converting. This is an attempt to make metric conversions a bit of fun. I have produced two powerpoints depending on the ability of your class: 1. highlighted to make the units stand out; 2. not highlighted.

The labels and thermostats on their new costumes have been mixed up so they need to convert Celcius to Fahrenheit and vice versa to see if the suits will withstand the temperatures they produce. It's simple substitution basically.

Show it for 20 seconds then they have to remember it exactly. I put the picture of me on there so they would concentrate on their reproduction rather than staring around the room, but feel free to change it to a picture of your choice!

Villains' Vending are having a Grand Sale but the printer has broken. Can you find the sale price of the items required by the villains?

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.

The students need to write a formula for the profit that 3 apps will make, writing them in words and algebra. The extension is to draw a graph of the formulae.

Erica's teacher thought she needed more practice on the binomial expansion with negative and fractional indices, including estimating a root using an expansion. She has, as ever, got it all wrong so needs your help. Designed to help students prove their understanding.

Three “Crack The Safe” activities on time problems, converting metric units and compound measures (speed and density). These contain six questions but ten possible answers meaning that students can self-check their answers (are they in the list of possible answers?) whilst the teacher can help those who require it. I use these as starters and plenaries but that is obviously up to you.
