These are the 5 centers I use in my classroom. Students are on a 15 minute station rotation. If you have a longer class, of course, you can make your centers longer.
We are a 1:1 laptop school so each student has their own computer, which works well for some of the stations, but they do not necessarily need their own computers for this; however, you will need classroom computers.
I have included an example with each center idea.
