We purchased the set, which was quite an expense for us and were pleasantly suprised to see the parent/teachers guide included. The product desciption could have been much clearer.

My daughter now asks for these math books more than workbooks/worksheets which I think were too busy and distracting for her. I think the story problems are excellent and though the language is antiquated our homeschooler finds that an interesting charm rather than a problem.
