A fun way for children to master the art of telling the time, allowing them to complete the activities over and over again using the special wipe-clean pen. Part of the Usborne Key Skills series that supports the maths lessons children learn at school, this entertaining book is filled with activities that build confidence in telling the time to the hour, half hour, quarter past and quarter to. Wipe-clean pages offer endless practice, and answers and secret notes for grown-ups are at the back.
