A fun challenge to try and work out the maths behind the fact that a dog will take the optimal path into a river to get a ball. Needs knowledge of visualising 2D motion distance speed time finding the minimum of a quadratic Provided with solutions

Practice questions covering Western Electric Rules Determining if a system is in statistical control Calculating upper and lower control limits Working backwards from limits to finding standard deviation or sample size Finding the probability of a rule being broken Provided with solutions

Revision resources targeting a particular area of the course. Each consists of a set of questions and full solutions. Chi Squared Distributions Mann Whitney Probability Regression Sampling Z and T Tests

An introduction, with simple questions on each of Distance, Time and Speed, then mixed questions. Full solutions provided.

A fun activity to solve numeracy problems in a team. Two difficulties and full solutions provided.

This is a series of questions aimed at making pupils more comfortable with dealing with formulas with fractions in them. I made this worksheet in response to a very bright class who had no problems with most formula but struggled rearranging fractions. Full solutions included. Edit: added another powerpoint of more questions

A fun activity to practice using simple tally marks, investigate a few other systems, then make up their own. Works especially well with low-ability classes, who all like making up their own tally systems.

A fun activity looking at number and letter palindromes. Works well for homework. Full solutions included.

This is a series of tricky challenges to complement usual class work, using a full range of maths skills: - trigonometry - simultaneous equations - algebra - fractions - area - logic Can be used as extensions or homework. Full solutions included.

This is four different whole class activities practising times tables. There are four versions of the same game, with increasing difficulty: - easy multiplication, up to 7 x 7. - slightly harder multiplication, up to 8 x 8 or 9 x 7. - all multiplication up to 9 x 9, with few easy questions - all multiplication up to 12 x 12.

A series of questions testing speed calculations, which are the ones pupils find hardest in DST. Full solutions provided.

An introduction to time. Reading the time from clocks, then difference between two times, and finally a challenge with times in the school weak. Full solutions provided.

Practise converting words to numbers, and numbers to words. Starts easy then goes up to things like 32 809 and millions. Full solutions included.

This is revision material for a range of basic techniques, finding e.g. - 2/5 of 20 - 25% of 40 - 35% as a decimal Full solutions included.

A series of basic questions testing these skills: • Use the four operations with whole numbers. • Use simple fractions in context. • Express numbers given in figures in words, and vice versa. • Use money in a range of contexts. • Interpret and use information. • Select the appropriate unit of measurement for length. • Measure to a required degree of accuracy • Perform calculations in everyday contexts. • Round to the nearest unit in context. • Use fractions and percentages in context. • Use 12-hour and 24-hour times for simple problems involving time. • Select the appropriate unit of measurement for length, weight or volume. • Order everyday objects according to weight or volume. • Perform calculations in everyday contexts. • Interpret and communicate information. • Use properties of shapes. • Use further measurement skills.

Pupils learn about money and get the chance to design their own coins. This activity is inspired by the Scottish Independence Referendum of 2014.

A whole class activity to practise basic skills of adding and subtracting, multiplying and dividing. Three different difficulties.

These two activities extend from 3 by 3 to 4 by 4 magic squares. Pupils design an individual magic square then search for symmetries.

This is a set of six puzzles presented as large scale Power Points. I used them as colour A3 posters for a monthly maths competition. Although they are challenging, they can all be solved without using any advanced techniques. Full solutions included. Edit: added two more puzzles
