After copying a class set, I cut all of them on the lines and send home the appropriate strip. I've considered sending the entire sheet home on Monday, but I worry they'll do it ALL on Monday and do nothing the rest of the week. I want them to practice a little bit a day.
By the way, I give my spelling tests on Thursdays so I can correct and record them so they're ready to go home in their Friday Folders.
I pretest on Mondays and assign them the appropriate list. I had three different lists per week. I've attached a copy of the homework for one of my "easy" lists.
