Query: Unique tool for teaching time-telling

This small book helps you teach children to tell time on a clock with hands. It includes a reusable test that may be presented again and again, thanks to a unique flap that conceals answers and also provides a wipable answer space. You turn to a page on a particular topic, e.g. "hours", and write the answers on the wipable area with a grease pencil or erasable marker. Simple, clear and practical!!!
