I am having no problem getting my son to use this book. We recently switched from unschooling and would have done it sooner if we knew of this series. It takes the guess work out for me. I now feel like I am providing a thorough education. My son & I are both feeling good about this choice of curriculum.
This textbook has really helped to show my 10 year old granddaughter why she needs to care for her body by eating healthy foods, balancing her exercise and rest, and listening to God's Word in how she treats her mind as well.
I used this book for my 6th grade son with ADHD. He loved it and the workbook. I highly recommend the lab kit, most everything is included, it makes it so easy. Repetition of concepts in multiple ways cause the child to learn without knowing it because they are having fun with all of the hands-on activities.
