This is a free-standing resource on simple fractions. It involves questions like 1/4 of 20 up to things like 3/7 of 14. It's taken from a Murder Mystery Package I wrote hence it includes a small riddle element at the end. There are two levels of difficulty (A is easier than B) that both have the same solution. Full solutions included.

An investigation for pupils about the classic Four Colour Theorem. Some background and examples, then a chance for them to have a go at. Makes a change from the usual end-of-term colouring!

These are extensive notes that I have made to teach this SQA Course. Includes many example questions and follow ups on Excel. I’ve also included here a course outline, essential exam skills and a practice exam with solutions. *Updated 2020 to have Course Notes for pupils (with spaces for answers) and Course Notes for teachers (answers filled in) *Updated 2022 with corrections

A Power Point that includes questions on finding 10% (and 20%, 30% etc) and another one for 15%, 25%, 35% et cetera, Useful for teaching the topic or just for practice.

This is a free-standing resource on ordering decimal numbers. It involves ordering heights like 1.5 metres, 1.43 meters and 145 cm. It's taken from a Murder Mystery Package I wrote hence it includes a small riddle element at the end. There are two levels of difficulty (A is easier than B) that both have the same solution. Full solutions included.

A group activity to practice using bearings. Each group designs a route (choosing how many paces and how many bearings for each leg of the journey) then swaps with another group to see if they can follow the given route. Each group will need a compass (or compass app on phone).

A series of pictures of the same school (Mearns Castle in Scotland) taken from further and further away. For each picture pupils have to work out which is the correct scale.

An interactive Who Wants to Be a Millionaire game focused on numeracy questions. The questions near the end get very tricky! They are on the following topics - percentage, area, ratio, factorising, probability, volume, negative numbers, difference of squares, scale factors, angles, sequences, DST I normally do this with pupils writing their letters on mini-whiteboards before the right answer is displayed, and you can also do something with the lifelines if you like.

A Powerpoint with the classic Monty Hall Problem, then variations with a multiple choice questions one hundred doors ten prisoners Solutions in the notes at the bottom of the Powerpoint slides

A Powerpoint introducing the following tricky problems for pupils to think about. -99 Coins 100 Seats on a Plane Special dice Expected wait time Pascal’s Wager Solutions in the notes at the bottom on the Powerpoint See also my resource on Monty Hall Problems

A Powerpoint introducing the basic game of Dobble, then delving deeply into how to arrange the symbols on the cards so that each pair of cards matches exactly once. Pupils will be able to make their own mini Dobble sets, with 7, 13, 21 or even up to the full 55 card set. This introduces uses the following areas of mathematics 2D geometry of lines and planes Magic squares and Latin squares

Duality is an important concept in understanding mathematical problems. Sometimes a problem can be ‘reveresed’ by considering it’s dual, for example swapping around lines and points in a triangle. This Powerpoint looks at how duality appears in the following contexts division and subtraction 2D shapes and 3D shapes 2D graphs including the Fano Plane

Magic Squares are just the beginning! A Latin square is a grid where each symbol appears exactly once in each row a column - recognisable to most pupils as being like a Su Doku. This resources extends that idea to look at double and further Latin Squares. These are useful for many things (see e.g. my other resource on Dobble)

A colourful poweroint introducing a new idea for most pupils. In standard 2D geometry parallel lines never meet. In projective geometry we add an extra point (infinity) where the lines meet. This turns out to be useful for various problems (e.g. see my other resource on Dobble).

This is a free-standing resource on addition and subtraction of whole numbers. It involves additions like 12 + 29 or 145 - 56 It's taken from a Murder Mystery Package I wrote hence it includes a small riddle element at the end. There are two levels of difficulty (A is easier than B) that both have the same solution. Full solutions included.

A series of increasingly difficult problems involving solving Trig Equations, in radians. Begins with sin x = 1/2, then builds in double angle formulas and trig identities. Answers given at the end.

A simple one-page practice on finding the area of lots of circles given the diameter or radius. Later questions are just fractions of circles.

Three sets of questions revising: - Trig Graphs - Sine Rule, Cosine Rule and Area of Triangle (everything except trig identities) Plus an extra couple of questions as a Homework Edit: added some Powerpoint slides for revision Provided with full worked solutions

A teacher-led Powerpoint investigation into randomness to be done at the end of a topic about probability. The five short topics are Pick a random number Heads and Tails experiment Lottery Random numbers Digits of Pi What is randomness? The aim is for pupils to understand that ‘random’ isn’t truly random after all!
