This is an investigation for pupils to discover that the more sides you have on a polygon, the closer the area comes to that of a circle. In fact, using polygons was how people once estimated pi. Skills used - trigonometry - area - algebra - Pythagoras Full solutions included.

A range of activities to celebrate March 14th (3.14), Pi Day! - whole class quiz - mnemonic activity (making up sentences) - three Pi Challenges involving some maths

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.

This is an investigation to get pupils thinking about different units. The Power Point begins with an introduction, then a few questions to get pupils thinking about different units, and finishes by describing the investigation they should do, finding out more about one type of measurement and presenting their results.

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.

This is an investigation into Pythagorean triples. Pupils will discover more triples, and also investigate using algebra to get a general solution. During the project they will learn to appreciate the value of working generally with algebra to find all solutions. Skills used: - Pythagoras (of course) - Fractions, including adding fractions - Algebra Full solutions included.

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

A 4-page write on worksheet exploring basic symmetry and diagonals and other properties of 2D Shapes. Full Solutions provided.

This is a 2-page write on worksheet that tests these basic skills: - Lines of symmetry - Names of 2D shapes - 2D shapes that can be convex and non-convex Pupils can write directly on the sheet. Full solutions included.

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.

This is a series of simple questions to give pupils practice in estimating a variety of different units in real life circumstances. The questions are straightforward but should produce a good basis of discussion. There is estimation in a variety of units and also some measuring. 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.

This is Power Point and practice questions to get pupils comfortable with subtracting a negative number. Rather than just stating that “it’s the same as adding” they will learn to do this instinctively, by thinking about temperature. Full solutions provided.

A problem solving project where pupils use Pythagoras to find how far away the horizon is, depending on your height about sea level. This is an open-ended project, where rather than being given all the information up front the pupils have to work in groups to explore the problem, then reflect on what techniques were effective. It practices several useful skills such as Pythagoras, circle geometry, expanding brackets and rearranging formulas. There is the scope for very good pupils to extend the project in interesting directions.

This contains a dynamic introduction to Stem and Leaf diagrams, using a sort of game. There are then examples to be worked through in groups, and further practice questions to be attempted individually. All provided with answers and commentary.

There are two comprehensive worksheets here practising basic skills with decimals. Full solutions included.

This is a series of questions testing the basic principles that there are 60 seconds in a minute, and 60 minutes in an hour. They start easy and get harder, including decimals and fractions. Full solutions included.
