The Khan Kids app has a couple of games to help young children learn to tell time. In one game, kids move the hands on the clock to the time asked of them.
In another game, kids learn about AM and PM using a number line. Then they set the clock to the time asked. The character describes activities they do during that time of day.
The app is ad free and available for Apple and Android devices. It’s a truly outstanding app for early reading, math and science skills.
