Problems should use the Courier font. Why? Every Courier font character uses the same amount of space. A comma is the same width as the number 5. This means that all of the numbers line up perfectly for carrying during addition and bringing the zero down in division. Are the problems too close together? Make sure you can distinguish between the problem number and the actual problems. The problem numbers should be less obtrusive. Students with and without ADD and ADHD can become distracted by too many distractions!? Are there too many problems on the page? Some authors attempt to pack in the problems, leaving little room for students to show their work. The opposite can also be the case. Maybe there are not enough problems to accurately assess student knowledge.
I have said "Don't Use Worksheets" about every way there is to say it, and each time I have included solid brain_based, researched reasons for this statement; and yet, I know that many people will ignore the science in favor of the convenience. It is very difficult to fight the tide when there are so many internet sites pushing worksheets at parents, and so many reputable textbook companies doing likewise. It is difficult to remember the reasons to avoid them when one has very little time to devote to working with math. Worksheets just seem so much easier than doing things any other way. Can they really cause harm?
