Students from all over the world will be participating tomorrow (March 4th in New Zealand). This is an on-line activity. Students can register as individuals (from home) or as a classroom.

My kids registered today, created a face (they really enjoyed that and are still tweaking it), and played some practice games. (Kids are placed by age and can advance through the levels. They play with other kids who happen to be on-line somewhere else in the world. It's fast paced and fun.)

Enjoy!
