The way the new New York State IEP's are, I have to probe (assess) my students progress frequently. For my students who have a goal of solving # of basic facts in x minutes, I assess every 2 weeks. Some of the students only need 40 addition facts, some need 100. I don't want to have to make different probes for every student, especially when I have 37 now! I figured the easiest thing to do was print 20 different 5 minute drills (100 problems). Some of my students, however, are overwhelmed by seeing 100 problems at once. I make a quick template for them that only shows one row of problems at a time.
