Ive downloaded dozens of learning games for my kids and the Teach Me group outshines all of them. My kids started playing them before they could even speak, and now at 4 and 5 years old they are miles ahead of any of their classmates. They can both read, spell and do math that other kids years ahead of them cant do. The careful, and gradual steps it takes to teach difficult concepts are genius and they have tons of fun doing it. Even the coin reward system helps to teach them the value of saving money. Fantastic learning tool. If I had one criticism though, I would suggest altering the way the programs let the kids know theyve given a wrong answer. The negative sound effect and red X have become something they both dread, to the point that it turns them off the game if they get one. My eldest refuses to even be in the room when my youngest plays for fear hell hear the sound. I think a better way would be a voice that just says "try again" or an option to turn the sound off, or provide your own sounds, or something along those lines.
