"100 Childcare Practices: Sandbox Play" Publisher: Seibundo Shinkosha Price: 980 yen I purchased this book intending to use it for sandbox play when I worked at a kindergarten. It was very helpful, as I wanted to effectively utilize the children's favorite activity, sandbox play. In particular, it describes approaches for different age groups, making it a very easy-to-read book. I keep it carefully on the bookshelf when not in use, so it's in good condition. However, please note that I have written my name on the last page.
