In my low-beginner listening class students learn how to recognize numbers in different contexts. One of the contexts is time. In addition to the practice provided by the textbook (“Skillful Listening & Speaking”), I use a map of world times zones to practice telling the time.
<< https://www.worldtimezone.com/ >>
It is a world map which shows current times in major cities. I simply zoom and scroll around the map while asking the class to tell the current time in a city. On this map minutes are the same, only hours change which allows students to practice a particular number again and again while I may also correct the pronunciation (the times do not change unless you refresh the page).
Also, you can use this tool to teach/practice telling the time:
<< http://www.visnos.com/demos/clock >>
It’s an interactive clock which allows you to move clock hands.
