My boys unanimously agree that they like the Complete-A-Sketch workbooks from Insight Technical Education.
These have been a great tool for both my sons as part of their drawing skills curriculum. The workbook is set up so there is a small completed sketch in one corner and then there are several guides marks on the larger portion of the page where the child will duplicate the sketch from the top. The back of the book describes it as “complex dot-to-dot”, but I have found them to be challenging for my very technically apt middle and high school age boys.
They have learned to use a straight edge and circle template with these workbooks. I have expected neat and careful work. Even so, these assignments are considered “fun” by my boys.
We will be ordering and completing the Advanced Complete-A-Sketch program later this year. One aspect of this program that I especially like is that now you can purchase the books as an ebook. The ebook version allows me to print a page for my son on demand which will be very handy.
I would recommend these workbooks for middle school age students and above. I purchased my Complete-A-Sketch curriculum from Rainbow Resource. If you purchase the print edition, I would recommend getting one workbook for each child since this is something you can not share.
