Algebra Number Sense Grades 5–8

What time is it in Cambodia?

I need help!  My daughter is traveling in Cambodia and we are supposed to Skype just before her dinner time in Phnom Penh, Cambodia.  What time is that here in Boston?Let you students help me figure out time differences across the International Date Line.

GMT, UTC, Zulu time, prime meridian, 0 degree longitude, 180 degree longitude.  This is very interesting problem solving with some world awareness.  Enjoy!
