Educational worksheet on time zones with exercises for learning to tell time and understand global time differences.

Let's solve this step-by-step based on the image you've provided. This is a time zone worksheet with three parts: reading clocks, comparing time zones, and writing out times in different cities.

Part 1: Look at the clocks and choose the correct option

We need to read each clock and determine what time it shows.

Let’s analyze each clock:

Clock 1 (Orange digital-style):
- The hour hand is between 10 and 11.
- The minute hand is on 2 → that’s 10 minutes past.
- So, the time is 10:10 → "ten past ten".

✔ Answer: ten past ten

Clock 2 (Yellow wall clock):
- The hour hand is just past 1.
- The minute hand is on 1 → 5 minutes past.
- So, the time is 1:05 → "five past one".

✔ Answer: five past one

Clock 3 (Green analog clock):
- Hour hand is between 6 and 7.
- Minute hand is on 8 → 40 minutes past.
- So, the time is 6:40 → "twenty to seven" (since 60 - 40 = 20 minutes before 7).

✔ Answer: twenty to seven

Clock 4 (Cuckoo clock):
- Hour hand is pointing to 3.
- Minute hand is on 12 → 0 minutes.
- So, the time is 3:00 → "three o'clock".

✔ Answer: three o'clock
