Time Zones Math Activities | World Time, UTC

Do You Speak Maths? – Time Zones takes students around the world as they calculate local times, cross midnight, organise international calls, investigate boarding passes and solve travel-based challenges.
Rather than practising isolated calculations, students use maths in meaningful situations involving world clocks, flights, sport, space missions, geography and everyday communication.
