A series of worksheets exploring the link between door codes, Euler Graphs and also De Brujn Graphs. This will introduce pupils to the concepts of - vertices - edges - degree of vertices - directed graphs

Two homeworks and a revision sheet on basic numeracy for National 4 Maths or National 4 Lifeskills Covers things like: decimals, money, fractions, ratio

A series of five homeworks covering the topics of - time (hours, days, weeks etc) - hourly salaries - tax - loans and repayments - money exchange - budgeting

A game to revise simple integration. Each catchphrase picture is hidden behind nine expressions. Randomly select a pupil, and if they can integrate their chosen expression they get 10 seconds to guess at the picture hidden below.

A simple powerpoint with a shop where items cost different amounts. You then ask the pupils how much change they get from a pound. Easily adaptable to add your own items (or change the existing prices) or extend by asking about buying multiple items, starting with £5 etc. Aimed at CfE Level 1 Mathematics

A simple powerpoint with all the different common words that indicate a pupil has to add (plus, together etc.) and all those that mean subtract (difference, change, etc.) Useful for pupils who struggle with questions with words in them. Aimed at CfE Level 1 (Scotland)

Two starters on calculating back bearings. The first relies on estimating bearings, the second on calculating a back bearing from a given bearings.

Some infinite sums that (if you go on long enough) add up to Pi. Pupils can try these with a calculator and see how far they get. More advanced pupils can think about which one converges the fastest, and why

A simple problem about inviting six people to a party - will there always be a group that know each other, or a group that are all strangers? An introduction to the idea of edges and vertices, in the form of a fun problem.

A simple worksheet with many questions such as 'reduce £70 by 20%'

Four worksheets covering the following topics - differences between times (minutes, hours days) - hourly wages (including time and a half and double time) Used for National 4 Lifeskills Finance Module

A powerpoint presentation to introduce the idea of functions having 'fixed points'. For example, the fixed point of f(x) = 2x - 5 is when x = 5. Goes on to talk about 2D fixed points, before finishing with a riddle that can be solved by thinking about fixed points.

A worksheet with four pre-printed distance-time graphs for pupils to interpret. Their answers should be sentences such as "go at 4 metres per second for 3 seconds, then pause for 2 seconds, then ..."

Everything you need to revise angles! The first Power Point covers - types of angle, angles in circle (360), angles on a straight line (180), angles in a triangle (180), corresponding and alternate angles, right angled and isosceles triangles The second Power Point covers - a big one-slide recap, a challenging question, places you might see some of the shapes involved

A series of four worksheets to progressively introduce pupils to the idea of adding and subtracting fractions by matching the denominators. Rather than just presenting it to them as a rule, they work through simple examples to gain an understanding of what is happening. I wrote this out of frustration with a poor class who simply didn't seem to understand how fractions worked, and although they could memorise a method, would then misapply it (for example, trying to add three fractions with them was a disaster, until they actually understood what they were doing)

Some not very exciting but essential practice, with increasingly difficult questions such as - 1/4 of 24 - two thirds of 12 - increase £20 by a fifth - find two fifths of £11 - decrease £9.99 by a tenth

Three Power Point slides with (fairly) easy questions on capitals, currencies, and shapes of countries.

A fun Power Point about Rowan Hamilton's discovery of Quaternions. There are no actual formulas given here (just a hint that it's about 4D space), the point of the presentation is just that he had a brain wave while crossing a bridge and carved it into the bridge. Can be used with a junior class talking about 'inspiration' or a more senior class who know about complex numbers if you want to go into the actual equations of quaternions.

A great way to introduce formulas, with a fun activity to estimate how fast your reaction time is. The Power Point introduces the idea of reaction time then shows pupils a simple experiment they can do, which leads to a formula for converting centimetres on a ruler to reaction time in seconds.

Tired of your usual lesson starters? These six Power Points are on - how old are you in seconds - using coins - a famous question solved by Gauss - penguins - pandas - temperature in the UK and US
