The LINK System is excellent, I could not function without it, especially for the primary grades. The feature that benefits me the most is to be able to control each individual computer and also to be able to demonstrate procedures to the class on their individual computer. I use the system all the time to show students how to do different projects step by step. One of the biggest benefits is it is much quicker to be at the computer and help students with questions than to walk around and help students.
