In February I came across a great new app called TeachMe: Kindergarten. It focuses on addition, subtraction, sight words and spelling. The app is completely customizable. You can add each student in your class, choose which area to target, set the difficulty level and choose specific questions. You can review their work and progress. Students stay engaged with a reward system. They earn coins for correct answers and can do various things with these coins. My kindergarteners were able to use this app independently and they love it! It is well worth the $0.99. There is also a TeachMe: 1st Grade and TeachMe: 2nd Grade.
