It was really great using the i-Pod Touch in class today to give students an opportunity for instant feedback when working with integers. One of the apps (Signed…Lite) gives various levels of quizzes offering excellent differentiation and immediate feedback for the students and the teacher. Other games like Pearl Diver and Zeroes offer learning in a fun game so students hardly realize they are learning. But, they really want to make the high score board so they do their best. This is great. I hope one day I can have the opportunity to see how apps are made.
