I keep having to re-do someone else's work

One of the reasons I decided to try the ENY materials was that I figured someone else had done the heavy lifting on planning and designing lessons etc. To an extent I was right. What I didn't figure on was blatant errors in their materials, such as "Who's help does so and so ask for when he can't do the work" and worksheets that just don't work for kids. They are too small, they are on multiple pages, or they simply don't make sense. I have had to rework a sixth grade "graphic organizer" and one for seventh grade as well just for this week, and it's only Monday.
