I recently received your unit study on Ancient China, I was wonderfully surprised. It was so detailed, so complete, so full of suggestions, resources, and links. My 8th and 9th grader have chosen Mandarin Chinese as their foreign language for the next 4 years. I decided to turn our foreign language time into a full unit study on China. YOU MADE THIS SO EASY!. I could even stretch out the work for almost a full year. Thank you for all of the time and work you put into this book. I have something to be excited about for the coming school year.
