Learn about the clock interactively? This works wonderfully with the BOOKii technology in this clock book! Children learn playfully to develop an understanding of times of day and daily routines. When does kindergarten start? What time does the family have lunch? And is it really time to go to bed? By tapping with the BOOKii audio pen, children can have all the explanatory texts read aloud, the pen makes people and objects speak, and the interactive games provide variety and entertainment. The pen is not included with the product; it is available separately in stores.
