Fun and simple. My little one liked BarWhat? 5000+ Trivia app and I do too. Though he hasn't played as much as I do (I'm a music buff-love the Grammy awards trivia) but he seems to stay interested when he does. Which is good for us. Beforehand I have been trying to train him Spanish days of the week (bilingual family). And there it was the days of the week in Spanish and English in BarWhat? 5000+. We tried to pronounce the names of days together as we chose an answer. Not only Spanish but other languages too - harder for us I admit. We learned about the Presidents of the United States too. I think it was worth 99 cents for my little one alone and the kick we both have gotten out of BarWhat? 5000+. I highly recommend.
