During the dry spell of summer, when our favorite TV shows were in their off season, my 10-year-old daughter and I got hooked on a fun Korean high-school drama series. But while we watched I noticed something I didn’t expect: her reading skills improved. And then I figured it out. Since the show is spoken in Korean, we had to watch with subtitles. She had to read fast to keep up with the plot.

For the first couple episodes, we did a lot of pausing and hitting the 10-seconds-back button to re-read what they were saying. But about 4-5 episodes in, she could keep up without having to stop and start. Without even realizing it, she was boosting those reading skills.

If you’re looking for a creative way to help your own kid’s reading skills, here’s how to turn on subtitles on your devices.
