As well as learning to read the time on the clock, children can lift the flaps to learn other concepts of time too, such as the difference between a fortnight and a decade, how many days are in a leap year and how to read a 24-hour clock. A great way for children to hone and develop time-telling and mathematic skills away from the classroom. Includes a clock to build, with pop out hands, to help answer the puzzles in a fast-paced time challenge. n
