Compared to Merriam Webster, it has more words, but the ads are more prominent. This makes it easier for them to find the words they need.ĭ: it is also free, with option to download the non-ad version. Since many time, kids know how to say the word, but don’t know the spelling. But if you don’t like the ad, you have option to buy the non-ad version via In-App Purchase. The free version has ads in it, but the ads mostly stay at the bottom of screen. Merriam Webster Dictionary: it is free to download. Since we first introduced dictionary apps, I have found some more good dictionary apps for kids, some are even free. With these apps, kids don’t have to carry those big heavy dictionaries with them, and they can not only check for spelling and meaning of the words, but also hear the pronunciations of the words. Children’s dictionary apps are great proof of how technology can help kids’ learning. One big advantage of mobile devices in education is the convenience it brings.
