I did not read this book in its entirety. Although I like the idea of the book, I don't find it particularly attractive and the style is very reminiscent of the early 90s. This book is all about measurement and it provides detailed projects to create your own measurement tools and also describes a variety of activities and experiments children can perform. The directions seem easy to follow and the images don't muddle the text. This book could be useful for an elementary teacher or parent for teaching children 7-10 years old. ( )
