I also tried hard to create them in a printer friendly way. There are three problem solving tasks per sheet of paper. So, you copy that sheet of paper times however many students you have, then cut in three pieces. You could just have them do each slip each day and turn in or take home, etc. But, I have them glue it into their math journals to have a kind of diary of all of them. Just my preference.
I like how the ones that I have made have been working so far this month, so I plan to continue to create them monthly for my class!
If you are interested in trying them out, here they are in my store: January Math Problem Solving Tasks
