"Problem solving is the cornerstone of school mathematics. Without the ability to solve problems, the usefulness and power of mathematical ideas, knowledge and skills are severely limited. Students who can efficiently and accurately multiply but who cannot identify situations that call for multiplication are not well prepared. Students who can both develop and carry out a plan to solve a mathematical problem are exhibiting knowledge that is much deeper and more useful than simply carrying out a computation. Unless children can solve problems, the facts, concepts and procedures they know are of little use.
The goal of school mathematics should be for all students to become increasingly able and willing to engage with and solve problems.
Problem solving is also important because it can serve as a vehicle for learning new mathematical ideas and skills."
Schroeder and Lester 1989

Able pupils often need support in developing skills to communicate their thinking, methods and solutions.
Here are some useful using and applying activities for you to try. They have all been tried and tested with children and teachers. Please note that some problems will fit into more that one category.
