I don’t like creating, printing, and then storing computation worksheets, especially when I have students who need to practice addition, subtraction, multiplication, or division in the same room.

What if they roll a die, write down the numbers on their own lined paper, solve the problem, and then check the answer with a calculator? It’s fun when they roll a lot of ones and are able to quickly solve a problem.
This strategy saves me from having to make sure to have adequate worksheets labeled in file folders that I hope my students keep organized while avoiding printing worksheets that are rarely used by my students. What if you spent a few minutes every day practicing computation skills before your class learns about other math concepts? You could walk around the room noting who needs support and meet in small groups to discuss strategies for finding sums, differences, products, and quotients. 
Your ideas about students rolling dice to create computation problems is so helpful! Thank you for your creativity and encouragement in my teaching. I find it helpful in tutoring one on one also.
Thanks for these ideas.
