Bond Brain Training: Number Puzzles has been designed by Bond, the market leader in 11+ test preparation, to develop children’s ability with numbers through problem-solving. The book is packed with number-based puzzles that are broken into Warm-up, Intermediate and Tricky levels, so that children can take on the challenge they feel best suits them. However, whilst the book looks and feels like fun, it is underpinned by Bond’s usual attention to the school curriculum and core SATs and 11+ exam skills, meaning that your child will be building essential number and arithmetic knowledge and reasoning skills without even realising.
