New timetable, low ability class and I needed some function machines.

Powers calculations to get correct so that the student can defuse the bomb successfully. This is based upon squares and cubes but ventures into other powers of 2 and 10.

Answer the indices questions, link them to the letters then unjumble the anagram produced to find out what Santa left in my stocking this year. This covers basic indices, fractional and negative.

Arrange equivalent fractions, decimals and percentages into 'family' photos. I have done the smartboard file to show on the board and drag the fractions etc into the right frame if you like.

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

A shopkeeper has dropped some boxes of Easter eggs and spilled the contents. Can you help him work oou how many of each sweet goes in the large and small eggs?

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.

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.

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?

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.

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

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

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.

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?

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.

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.

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!
