An original STEM book that introduces kids to the concept of time and teaches them how to tell time on digital and analog clocks. Four small space travelers are excited to eat pizza. But… what time is it? Join the little astronauts and their Martian friend on their intergalactic adventure and discover what hours, minutes, and seconds are.

Learn the differences between digital and analog clocks and, of course, find out how long it takes to eat a delicious, mouth-watering pizza in space! Veteran non-fiction children's book author David Adler incorporates mathematical concepts such as addition and subtraction into this fun narrative. A useful tool for understanding the concept of time and hour, it includes a glossary explaining time zones, daylight savings time, and more.

What they said about the book: “Miller’s fresh, colorful palette soars with the little astronauts, while Adler, as always, adapts the language and examples to the level of children… It’s time to add this to your collection.” –Kirkus Reviews
