I've had iPods, Macbooks and netbooks in my class for several years. I use the laptops as stations during math rotations. iPods are sometimes used this way as well, depending on the lesson. The laptops are also used by students without access to computers at home so that they can access Edmodo.
In this upcoming year, I'll be receiving iPads and I'd like students to use apps like ShowMe to record and share their answers or explanations to questions. They could even create their own word problems to share with the class.
Select students in each class are in charge of caring for equipment.
