This book is aimed at gifted & talented students in year 9 although it can also be used as appropriate with students throughout the 11-14 phase. It consists of tightly focused sets of problems with each set devoted to core ideas from the Framework but approached in a way that cultivates more profound mathematical thinking. The book is structured into a number of sections which comes in three varieties: tasters core & extensions thus recognising differentiation within the gifted spectrum. The materials can be used within ordinary lessons for top sets.
