Sumdog's educational games are used in thousands of schools worldwide. They motivate children to learn! As children play, they answer questions - each one personalized to that child's needs. Meanwhile, Sumdog's adaptive learning engine guides their progress. It gets to know each child, guiding his or her learning, while reporting back to parents on progress through the standards. Sumdog is unusual, in that your child can practice any skill with any game. It's great for motivation: when you move on to a new skill, you can still use your favorite game to work on it.
