Learning to Tell Time with Puppies and Kittens [PDF ebook] 

Adorable photographs of puppies and kittens guide elementary students though the basics of telling time. Starting with ‘Words to Know, ‘ which introduces students to new vocabulary before encountering it in the text, this volume proceeds to explain how to read time from analog and digital clocks to the half hour, the difference between a.m. and p.m., and the various ways to write the time. Fact boxes and activities enhance the math concepts. A further reading list with books and websites provides additional sources of information.
