I have transitioned all of our morning work (first 1/2 hour or so) to iPads.
When students arrive they use Socrative to let me know they're present and whether they're buying lunch or not. Next they move to an iPad activity that was formally completed on paper.
Monday--Showbie activity to review 2nd grade concepts (I'm working on transferring 1st grade material to Showbie as well)
Tuesday--math fact test and daily sentence edit
Wednesday--Socrative math and grammar questions
Thursday--math fact test and daily sentence edit
Friday--spelling test and Showbie logic/problems solving activity
After 2 weeks my students know the routine, understand the work flow, and I find they are completing the activities so much faster than when they were doing the same thing on paper. I also love the way it frees up my time to meet individually or in small groups to quickly review topics from the previous day or check in with students who were absent.
