Extract discrete data from a bar chart and use to find mean, median, mode and range. Starts by considering a table of data and then two examples of bar charts.

Fill-in worksheet introducing correct way to name angles/lines and identifying alternate/corresponding angles. Goes on to get students to identify and then write correct geometric reasons. Answer sheet to match (although student sheet slightly reconfigured since to give correct names for angles). Meant as a reasonably easy introductory resource once key ideas have been explained from the board. Hopefully accessible to my Y7s (Yup!) Second worksheet (with answers) emphasises reasons for each angle

Presentation that introduces factorising by trying to split arguing kids into equal groups with equal numbers of adults. Goes on to algebraical representation without pictures. Worksheet and answers now together here

Spreadsheet that calculates chronological ages. It works (I hope!) correctly for months of different lengths etc. (No awkward cludges of dividing days by 30 to get months.) First tab on the sheet is set up so you can enter a whole class. The second tab is just for quickly checking single dates of birth. The main calculations in the first tab are carried out in columns D to J, which are hidden. If you look at the formulae, you will see that the formula is far from elegant - but calculating chronological ages is not an elegant process! I realise that the year calculation could be simpler, but I couldn't be bothered to edit it...

Brackets are compared to party bags! So expanding is just finding out how many items altogether. Hopefully simple, visual explanation of concept followed by some quick questions. Used alongside mini-whiteboards.

This links factorisation of linear expressions (where the term in the bracket is in the form y=m(x + c/m)) to the intercept with the x-axis. It lays the foundation for the same concept when factorising quadratics. It could be developed by examining y = c - mx or y=m(ax + c/m).

Worksheet generator: 6 sets of 3 randomly generated activities based on key mathematical skills selected by the teacher on single page for printing. Add, subtract, multiply, divide, place value operations, decimals, negatives, BIDMAS, rounding, percentages, fractions... Each pupil in the class is allocated 3 topics to complete in lesson/homework. Idea is to get all 3 questions right for your 3 topics. When pupil gets all 3 questions correct for any given topic, they get a sticker on a pupil record sheet. 3 stickers for that topic means they have mastered it and will not have to do it again :) Warning: Macro-enabled spreadsheet. Macros MUST be enabled when you load the sheet in order to use the navigation and copy/paste buttons. Read the Instructions document for further details. A Teacher Record (for use on your computer) and a Sticker Sheet (to put on your wall) are provided. [12/7/16 Minor improvements/additions]

Simple intro to translations. Describe movement of car around track using translations. Draw own track and do the same. Promethean flipcharts (old and new versions) and worksheet.

6 pairs to match. 3 with full dimensions (one unit conversion needed). 3 with end area and missing length, but should be able to match by eliminating possibilities. Find missing dimension for last three (all integer values).Quick starter/plenary.

Shade diagrams to add fractions. Fractions without common denominators. First 5 when in same times table, then 3 in different tables. These diagrams pre-drawn and not explained; plus seven questions where pupils need to draw diagrams in their own books. (Assumes the general idea is already familiar from earlier in curriculum, but you may wish to discuss common denominators and equivalent fractions before they go on to drawing their own diagrams.) Updated 16/1/16 - second worksheet with more examples added

Add/subtract mixed with multiply/divide, seeking to clarify which signs you need to look at when deciding how to use signs in the answer.Straight-forward worksheet (2 copies per sheet - chop in half!).

A presentation showing how to divide by (say) 0.2 or 0.5. Introduces idea at the end of rewriting the sum by increasing both dividend and divisor by power of ten.Supporting file has decimal number lines (0-5, 3 different sets of scale markings) for printing on A3 for students to use - you may want to cut up and laminate.[15/7/15 improved from user feedback]

Worksheet to draw and measure interior and exterior angles for a pentagon. 2nd worksheet to divide polygons into triangles for total interior angles.\n\n(I have previously posted a worksheet to complete for int/ext angles of regular polygons)

Partners take turns to coach each other in rounding numbers to required decimal places or significant figures.

Fairly basic set of 15 Qs to be used with flashcards, whiteboards etc. Covers integers with indices and algebraic expressions. Add/subtract rules. Useful as revision or building up to add/sub simple powers.

Quiz, loosely based on Deal or No Deal. #1 has brackets but easier numbers; #2 has (simple) algebraic fractions; #3 negative and decimal answers.\n\nThe player has an amount of money. The boxes contain algebraic expressions that say what that box is worth. So, if the player has £100, 2x+50 gives a box value of £250. \n\nIt could equally be played as a quiz between two teams or individual players trying to get the highest value box.\n\nOriginal idea inspired by CrazyTalk clips on YouTube linked by Keith Ennis.

Visual of seesaw showing how to keep simple equations balanced while solving. 2 quick examples, but it should be easy to create more by copying and amending slides.

Scaffolded worksheet on fractions of an amount using fairly simple quantities.

Powerpoint demonstrating how to divide sums of money in ratio and accompanying scaffolded worksheet with (fairly) straight-forward examples to work out. (10/2/14) Second, slightly harder, worksheet added.

Powerpoint in Millionaire format. All 4 rules for fractions, starting from add/subtract then multiply/divide. Mixed numbers and simplifying involved at different points. [6/5/15 edited to remove duplicate false answer on Q1.]
