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

Two pages of tricky riddles, that will keep pupils busy. The second page is much harder than the first. Solutions provided.

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

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

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. Full solutions included.

This is a five round team picture quiz that takes about 50-75 minutes to do completely. The questions are not too serious and everyone should be able to have a good guess. Full solutions included. (updated 2022)

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.

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

This project gives pupils some real life houses from around the world to practice finding the area and perimeter of. The package includes an introductory Power Point then a series of tasks, culminating in designing their own shelter. Skills used: - Area - Perimeter - Units - Scale drawing - Budgeting Full solutions included.

This is a series of questions that will guide pupils from thinking only in numbers to thinking algebraically. The questions are increasingly challenging, finishing with some that require a lot of thought and can be investigated further.

A bumper collection of resources for Factorizing Quadratics, including various activities and games and plenty of practice questions, which also include the other types of factorizing required for 9th and 10th grade. (Note: Some of the embedded equations may not display properly on the TES preview but they all display perfectly on the downloadable files)

A series of projects on rearranging formulas. (Note: Some of the embedded equations do not display well on the TES preview but they all display perfectly on the downloadable PDFs) Each project is linked to real life situations, and also includes lots of practice at other 9th Grade / 10th Grade Skills: standard form, algebra using brackets, volume formulas, rounding, units, surds .

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.
