18 questions, in two groups (for pairs of pupils to work on). Makes a penguin, sort of! Errors now fixed and answers added to second page.

Story with words made by turning calculations upside down. Gives practice using powers, mixed numbers etc. without being too boring. You have to imagine you're using an old calculator, but I&'ve included a key to facilitate this. Answers included on second page of document. Last question includes the factorial button which I realise isn&';t KS3 but 'try some numbers and try to work out what the ! key does' keeps the early-finishers busy for a couple of minutes!

Multiple-choice fractions of amounts questions disguised in a more exciting form. 3 levels of maze (unitary fractions, whole number answers, some answers with halves) plus a blank one for students to make their own. (Only the roads containing the correct answers can be travelled through). Quick to mark as you're looking for a general shape, not all the correct numbers!

PowerPoint test going through each of 10 parts of a circle gradually (segment, semicircle, radius, chord, tangent, diameter, arc, centre, sector, circumference). Ideal for GCSE revision. Second PowerPoint is a test on the words learnt, intended for use the following lesson but could also be used for revision.

This is an adaptation of one of Gill Hillitt's excellent tarsias (which I found via Mr Barton), where factorisations lead to animal names. I wanted an easier version where the coefficient of x squared is always 1, so I made this. I&'ve uploaded it as a word file / pdf because pictures within Tarsia aren&';t portable. (Plus homework sheet.)

suitable for KS4 and core 1. Introducing surds and the rules for manipulating and simplifying surds. Can be printed out as a worksheet. Multiplying and dividing surds together with short sets of questions to practise each rule. Example to show that (different) surds cannot be added. Exam question to finish. Picture on title slide is 'square roots' (worth asking the class what it is a picture of - if they like bad jokes!)

Used for introduction to conversion graphs with a Year 7 maths class. Example given using splitting up a ruler to demonstrate a centimetres to inches conversion graph. Opportunities for pupils to come up and answer conversion questions using the graph. Worksheet uses a cake recipe to put conversion into context.

Great for Revision. True/false sorting activity (10 statements about best-fit lines to target misconceptions / deepen understanding) with accompanying ppt on scatter graphs. Plus set of simple, clear graphs/description posters showing different types of correlation (for class questioning assessment / matching activity / display).

Finding a percentage of a number. Calculating percentage increase and decrease. Finding one number as a percentage of another. The picture was from another website but I can't find it so can&'t acknowledge it.

Worksheet with two questions. First question makes a picture of a present (vertical/horizontal lines only), the second makes a tree (includes diagonal lines). Used for Year 9 but also suitable for GCSE. Answers included.

Deciding what average to use? Comparing data using mean, mode, median and range. Powerpoint with accompanying worksheet (for pupils to discuss first) comparing English and Maths test scores. Uses stuff from BBC Bitesize website, plus an exam question on marathon times for plenary. Pretty straight forward.

Lesson Powerpoint: Be able to differentiate the product of two functions using the Product Rule. Suitable for core 3, A2 level mathematics. Intro, examples and questions, using differentiation of polynomials only (no sin, cos, exponentials etc.). Created to be suitable for C3, MEI syllabus.

Plotting 3D coordinates on triangular isometric paper to create a picture of a house.

Rotation worksheet + ppt with answers. Shapes create a giraffe and a camel when rotated, though my Year 8s thought the giraffe looked more like a unicorn... (Inspired by Tristan Jones' transformations jigsaws.)

Reflection, Translation, Rotation and Enlargement Powerpoint which could be used as worksheets. 5 multiple choice questions on transformations aimed to expose misconceptions. Plus an estimating question from pictures - what is the scale factor of the enlargement of a normal sandwich to the world's largest sandwich? (Use average height of a person for scale.) I have added 3 slides on translation, as suggested, in case you want to add them in.

10 rounds of 4 quick questions on a range of non-calculator topics. Designed for a Year 11 class. They had 4 in a team and 4 whiteboards to put the 4 answers on.

Logarithms and Exponentials Revision: Worksheet / Test with questions that are my own (not real exam Questions). My students didn't feel there were enough questions in the textbook for practice. Answers given (handwritten).

Just a quickie showing some examples of how to divide by a decimal by using equivalent calculations (i.e. whole number denominators).

Instructions to create a picture (of a swan) using enlargements with negative scale factors only. Fits in an exercise book (landscape) but students may need help drawing the axes or to be given them already drawn (with hindsight!) (Inspired by Tristan Jones' transformation jigsaws.)

Proof of Sum of Geometric Series: steps in proof of the Sn formula. Pupils need to cut out the steps and rearrange them into a full proof. Essentially the same as the NRich interactive resource http://nrich.maths.org/1398 but this was too small to see on my interactive board and I wanted everyone to have a go so made a paper version.

Organised into one document under headings by topic, so students can practise one topic at a time. (Past papers questions copied from Jan 08, June 08, Jan 08, Jan 09.) Now also available in Word 97-03 format. For answers use corresponding markschemes (available on Edexcel website). P.S. Question-generator on all core topics on nrich site is pretty awesome. (Good for revision starters!)
