Proabably a compromise is in order in the sense of some pages have 3 shapes to trace and that is it. Others you simply circle the correct answer and move on. Neither takes enough time to warrant the printing unless you are going to have the children do the work and then turn the page over and draw/scribble what they want. For the ages we deal with the worksheets are only minimally useful anyways. You could accomplish just as much using a magnet chalkboard or whiteboard. Put two seasonal pictures on the board and have the child draw a line from one to the other or from what in row one matches row two. Erase and let next child have a turn. You can also do the same with file folder type games. From the amount of artwork I see crushed in the bottom of backpacks I find it hard to believe that the parents are appreciative of the what you are printing. I would be inclined to rethink it's usefulness. If nothing else print in draft mode which will use the least amount of ink but still be dark enough to serve the purpose.
