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 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.

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

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

This is a series of questions testing basic knowledge of percentages. They should be solved by converting the common percentages to fractions. They start easy then introduce increases and decreases, then more difficult numbers. Full solutions included.

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.

Two worksheets, testing basic probability with dice, coloured balls and letters. The second worksheet is more difficult and introduces sampling with and without replacement. Full solutions included.

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.

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

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

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

A series of worksheets revising negative numbers. - addition and subtraction - subtracting negative numbers - multiplying and dividing - all operations, with fractions and decimals Full solutions provided.

Practice multiplying and dividing - first of all 10, 100, 1000 etc. - then by 20, 300, 4000 etc. - then using decimals, e.g. 1.3 x 300 A series of worksheets revising these basic skills. Full solutions included.

This is two worksheets practising 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.

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.

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. These puzzles are challenging and give the scope for comprehensive answers. Full solutions included.

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 using standard techniques. Full solutions included. Edit: added two more puzzles
