Number Facts is a series of activity books designed to foster fluency in number facts (or ‘tables’) for primary school children. This attractive and engaging series features an innovative approach to basic number facts, teaching children to understand, not just do, maths. In contrast to traditional drill-and-practice workbooks, which just test whether the answer is known, Number Facts teaches children to visualise numbers pictorially and to use these images and thinking strategies to become more adept at manipulating numbers, thus also enhancing their mental calculation and problem-solving skills.
