The Toys Train app, by 22learn, LLC, rewards children with stickers. Need I say more? Preschoolers will love this app! Children love positive reinforcement when it comes to learning, and this app allows children to select a sticker to place in the provided "virtual sticker album" when objects are correctly identified and each level is completed.
Not only does the app provide incentives for correct toy identification, the word of each object is also identified and spoken, so that children can see the object, as well as see and hear the actual word. Also, as the child progress through the app, the level of difficulty increases, allowing the child to be constantly challenged.
This app is a wonderful tool for early-aged preschoolers. Many toddlers are exposed to technology, and this app provides both learning and fun! I highly recommend this app to anyone with young children!
