A series of fun challenges working out what comes next. Some are mathematical, some require more lateral thinking. Good as an extension activity. Full solutions provided.

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 series of four worksheets to give some background algebra, do plenty of examples finding a limit, then for advanced pupils go on to find a general formula for a linear sequence. If you follow this through you will be able to instantly work out the value of the 50th term of u_n+1 = 0.4 u_n +3 (for example). The four worksheets are: - Indices (practice on this) - Algebra (rearranging formula) - Sequences (standard questions on finding limits, and graphing the results) - Investigation (putting it all together to get a general formula) All provided with full solutions.

A simple introduction with adding and subtracting money, then sharing it between people, then looking at discounts. Full solutions included.

A worksheet investigating different coins, and using them to add up to different amounts. Starts easy, then challenging at the end. Practice for arithmetic, dealing with decimals, and basic numeracy. Full solutions included. Now includes accompanying Power Point which revises lots of the same skills.

This will introduce the topics of 3D volume and surface area, and also provide some challenging extension questions. A set of four worksheets on - Basic Skills (rounding, 2D perimeter and area, 3D volume and surface area) - Problems (real life problems involving volume and surface area of cuboids, cylinders, cones and spheres) - Units (converting between e.g. square metres and square centimetres) - Extensions to the Problems (revisiting the problems with converting units and more in-depth calculations) All provided with solutions. Also includes a Power Point for some revision

This is two worksheets practicing some important basic skills. The first worksheet is powers of ten and multiplication. The second worksheet introduces two-step multiplication (e.g. multiplying by 20 is ×2 and ×10) and division. Full solutions included.

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

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

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

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 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 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.

This is an investigation for the whole class to do at the same time, investigating the seemingly simple idea of the four corners of a rectangle. It will force pupils to get out of the simple thinking that every rectangle has to be lined up with the co-ordinate axes, with a horizontal base and vertical sides. Can be done visually, or for more able pupils with algebra and straight lines. Full solutions included.

Two sets of worksheets with solutions on - frequency tables - mean, median, mode and range

A Power Point presentation investigating the not-so-obvious question of where the centre of a triangle is. Useful to revise and motivate some of the line work in e.g. Higher Maths Starts with the centre of other shapes (e.g. circle - easy) before introducing the main candidates for the centre of a triangle. These are where the medians, perpendicular bisectors, and altitudes meet. But there are also many other centres. And what about quadrilaterals, or 3D shapes?
